Hydrocarbons exploration rebounds

1 March 2023

MEED's upstream oil & gas report also includes: Energy security facilitates upstream spending

 

The world, and particularly countries in the Middle East and North Africa (Mena) region, remains undeterred in its quest to find more oil and gas resources, despite headwinds from energy transition activity and falling long-term hydrocarbons demand forecasts.

Last year, the global oil and gas exploration sector had its strongest year in more than a decade. In its effort to improve portfolios by adding lower-carbon, lower-cost advantaged hydrocarbons, the sector created at least $33bn of value and achieved full-cycle returns of 22 per cent, at $60-a-barrel Brent prices, according to a recent report from Wood Mackenzie.

Julie Wilson, director of global exploration research at Wood Mackenzie, says 2022 was “a standout year for exploration”. 

“Volumes were good, but not stellar. However, explorers were able to drive very high value through strategic selection and by focusing on the best and largest prospects. 

“The discoveries bring higher-quality hydrocarbons into companies’ portfolios, allowing them to reduce carbon by displacing less advantaged oil and gas supplies while also meeting the world’s energy needs.

“The highest value came from world-class discoveries in a new deepwater play in Namibia, as well as resource additions in Algeria and several new deepwater discoveries in Guyana and Brazil, where the latest wave of pre-salt exploration finally met with success,” she says.

“The average discovery last year was over 150 million barrels of oil equivalent, more than double the average of the previous decade,” she adds.

The exploration sector continues to be dominated by national oil companies (NOCs) and majors, with QatarEnergy, France-headquartered TotalEnergies and Brazil’s Petrobras leading the way in net new discovered resources in 2022, according to Wood Mackenzie. In total, NOCs and majors accounted for almost three-quarters of new resources discovered, the research consultancy said.

Qatar’s overseas footprint

In addition to raising gas production capacity from the North Field gas reserve and carrying out a liquefied natural gas (LNG) output expansion programme, QatarEnergy has been pursuing an overseas offshore oil and gas exploration and production (E&P) campaign in recent years.

The state enterprise has been investing in expanding its international upstream footprint, particularly in the gas space. In the past five years, QatarEnergy has acquired interests in gas-rich offshore blocks in Angola, Guyana, Kenya, Egypt, South Africa, Argentina, Mozambique, Morocco, Cyprus, Mexico, Brazil, Oman, Suriname and Canada.

In December, QatarEnergy won an offshore exploration block in Brazil in a consortium with TotalEnergies and Malaysia’s Petronas. QatarEnergy will hold a 20 per cent working interest in the Agua-Marinha production sharing contract, with TotalEnergies holding 30 per cent and Petronas Petroleo Brasil holding 20 per cent. Brazil’s state energy producer ANP will be the operator of the block, with a 30 per cent interest.

QatarEnergy also recently acquired a 30 per cent interest in exploration blocks four and nine off the coast of Lebanon. TotalEnergies is the operator of the blocks, holding a 35 per cent interest, with Italy’s Eni owning the remaining 35 per cent.

Oman E&P arena

Oman hosts the most foreign hydrocarbons E&P companies in the GCC. Majors such as BP, Shell and TotalEnergies have been present in the sultanate since the early 20th century, while smaller international upstream players have also been looking for – and producing – oil and gas for the past three decades.

The majority state-owned Petroleum Development Oman (PDO) operates the sultanate’s biggest and most prolific hydrocarbons concession, block six. The smaller oil and gas concession areas are operated by firms headquartered overseas such as Eni, Occidental Petroleum, Tethys Oil and Maha Energy, as well as by local firms such as ARA Petroleum, Majan Energy & Petroleum and Musandam Oil & Gas Company.

Oman’s Energy & Minerals Ministry signed a concession agreement in December 2021 with a consortium led by Shell’s Oman subsidiary, Shell Integrated Gas Oman, to develop and produce natural gas from block 10 of the Saih Rawl gas field.

The consortium comprises Omani state energy enterprise OQ and Marsa LNG, a joint venture of France’s TotalEnergies and OQ. The concession agreement established Shell as the operator of block 10.

By late January, Shell had started producing gas from the Mabrouk North East field located in block 10.

In September last year, the Omani energy ministry signed another E&P agreement with Shell and France’s TotalEnergies to develop block 11, which is located adjacent to block 10 and is understood to be rich in natural gas reserves.

Shell and TotalEnergies will own 67.5 per cent and 22.5 per cent stakes in block 11, respectively, with OQ holding the other 10 per cent. Shell is the operator with the majority stake in the concession.

UAE makes strides

Abu Dhabi National Oil Company (Adnoc) has completed two upstream concession licensing rounds in the past

four years, attracting oil and gas producing companies from the US, Italy, Pakistan, India, Thailand and Japan to explore for resources.

Offshore block two, which is operated by Italian energy major Eni with Thailand’s state-owned PTT Exploration & Production Public Company (PTTEP), has so far yielded two discoveries with combined estimated reserves of up to 3 trillion cubic feet (tcf) of gas.

In addition, in May last year, Adnoc announced the discovery of 650 million barrels of onshore crude oil reserves in Abu Dhabi, which increased the UAE’s hydrocarbons reserves base to 111 billion stock tank barrels of oil and 289 tcf of gas.

Adnoc also awarded Malaysia’s Petronas a six-year concession agreement in December to explore and appraise oil in unconventional onshore block one, deemed to be the Middle East’s first unconventional oil concession.

In Sharjah, Eni won stakes in all three upstream concession areas offered by Sharjah National Oil Company (SNOC) to international investors in the emirate’s first competitive hydrocarbons block bidding round, launched in June 2018. 

In January 2019, Eni successfully secured 75 per cent, 50 per cent and 75 per cent stakes in SNOC’s concession areas A, B and C, respectively.

Then, in October last year, PTTEP acquired a 25 per cent stake from Eni in area A, as a result of which Eni’s share in all three concession zones is now at 50 per cent.

Sharjah’s oil and gas fortunes reversed in January 2021, when SNOC, together with its partner Eni, announced the start-up of the Mahani 1 gas well. This marked the commencement of gas production from the Mahani field, located in area B, the first such onshore hydrocarbons discovery made in Sharjah in 37 years.

Energy security facilitates upstream spending

Bahrain labours on

Bahrain announced the discovery of the large Khalij al-Bahrain offshore hydrocarbons basin – estimated to contain 80 billion barrels of oil and 10-20 trillion cubic feet of gas – in April 2018.

Nearly five years later, Manama has been unable to make significant progress on the commercial appraisal of the oil and gas resources base. However, the lack of success with Khalij al-Bahrain has not deterred the country from continuing its exploration elsewhere.

In November, state energy conglomerate Nogaholding announced the discovery of natural gas in the two reservoirs of Al-Jawf and Al-Juba. The gas deposits are unconventional and situated in the Khuff and Unayzah geological formations.

Mena players make progress

Iraq, Opec’s second-largest oil producer, continues to seek more hydrocarbons resources in its territory. As recently as in February, the Oil Ministry awarded six oil concessions as part of the country’s fifth licensing round.

Three E&P concessions – one in Basra and two in Diyala governorates – were awarded to UAE-based Crescent Petroleum. Three others, also in Basra and Diyala, were awarded to China’s Geo-Jade Petroleum.

Eni’s discovery of the large Zohr gas field in the Mediterranean waters in 2015 elevated Egypt’s status as a significant upstream market globally, and the country’s government intends to continue to attract more E&P players on the back of this success.

Egypt’s hydrocarbons reserves spiked in 2022 with 53 new oil and gas discoveries: 42 oil wells and 11 gas wells, according to the Petroleum & Mineral Resources Ministry. The discoveries were made in Egypt’s Western Desert region, the Suez Gulf, the Mediterranean Sea and the Nile Delta.

So far in 2023, US-based Chevron, which operates the Nargis offshore concession in the East Mediterranean, together with its partners Eni and Egypt’s Tharwa Petroleum, has announced a discovery of Miocene and Oligocene gas-bearing sandstones.

At the start of this year, Egypt also launched an international licensing round for exploration rights in the Nile Delta and the Mediterranean, comprising 12 onshore and offshore blocks.

“There is a lot of uncertainty in future long-term demand scenarios for oil,” says Wilson. 

“Explorers are accelerating oil exploration to meet near- and mid-term demand, while gas exploration was focused in geographies that can supply the gas-hungry European market. In some cases, major leases are approaching the expiration of the exploration term and companies are pushing to optimise their value.”

She concludes: “By 2030, fast-tracked development of these new discoveries could deliver 1 million barrels a day in oil and half a million barrels a day of equivalent gas production, generating $15bn in free cash flow.”

  • Egypt raises gas prices by 30% amid Iran war

    11 March 2026

    Register for MEED’s 14-day trial access 

    Egypt’s Petroleum & Mineral Resources Ministry increased the price of several petroleum products and natural gas for vehicles on 9 March, according to official statements.

    The price of natural gas for vehicles has been put up by 30% to E£13 ($0.25) a cubic metre.

    The price of diesel has gone up by 17% to E£20.5 a litre, while 95-octane petrol has been put up by 14.2% to E£24 a litre.

    The new prices were put into effect early on 10 March and come amid soaring global energy prices in the wake of the US and Israel attacking Iran on 28 February.

    Egypt’s Petroleum & Mineral Resources Ministry said: “This comes in light of exceptional circumstances resulting from geopolitical developments in the Middle East and their direct impact on global energy markets, which have led to a significant increase in import and domestic production costs.

    “Disruptions in supply chains, increased risk levels and higher shipping and insurance costs have resulted in a substantial surge in global crude oil and petroleum product prices, levels not seen in energy markets for years.”

    The statement also said that Egypt is continuing efforts to boost domestic production and reduce the country’s import bill.

    Egypt, the Middle East and North Africa region’s biggest liquefied natural gas (LNG) importer, is facing uncertainty over its LNG supplies in coming months.

    Between March 2025 and February 2026, Egypt imported 9,440 kilotonnes of LNG, with the majority of its imports purchased through short-term agreements, mainly with third parties like trading houses.

    Last year, it was reported that Egypt had signed deals for around 150 cargoes through to the summer of 2026.

    While much of Egypt’s LNG is likely to come from the US, and will not be directly impacted by the effective closure of the Strait of Hormuz, the recent surge in LNG prices could mean that the North African country will struggle to afford shipments.

    Exacerbating the need for increased LNG imports, on 28 February, Israel shut down production from its offshore gas fields due to security concerns, cutting pipeline exports to Egypt.

    Prior to the fields being taken offline, Egypt was importing about 1.1 billion cubic feet a day from the Tamar and Leviathan fields.

    On 4 March, addressing concerns about energy supplies in the country, Prime Minister of Egypt Mostafa Madbouly said that Egypt had just concluded “several contracts” to procure gas shipments at “preferential prices”, in cooperation with several countries and international companies.

    However, he did not provide details about the exact pricing of the deals.

    On top of the LNG deals Egypt has with trading houses, in January, Cairo signed a memorandum of understanding with Qatar related to 2026 LNG imports.

    The preliminary deal included plans for 24 LNG deliveries through the summer of this year, when energy demand typically peaks.

    Now, the shuttering of Qatar’s export terminals and the effective closure of the Strait of Hormuz are casting a shadow over the deal and there is increased uncertainty over whether these deliveries will be executed.

  • Delays expected to $3.3bn Kuwait gas project due to Iran war

    11 March 2026

    Register for MEED’s 14-day trial access 

    Significant delays are now expected for state-owned Kuwait Gulf Oil Company's (KGOC's) planned tender for the development of an onshore gas plant next to the Al-Zour refinery, according to industry sources.

    The project budget is estimated to be $3.3bn and the last meeting with contractors to discuss the project took place in Kuwait on 10 February.

    In February, contractors were told to expect the invitation to bid to be issued in late March, but this schedule is now expected to be extended significantly due to uncertainties created by the US and Israel attacking Iran on 28 February

    Under current plans, the plant will have the capacity to process up to 632 million cubic feet a day (cf/d) of gas and 88.9 million barrels a day of condensates from the Dorra offshore field, located in Gulf waters in the Saudi-Kuwait Neutral Zone.

    Ownership of the field is disputed by Iran, which refers to the field as Arash.

    Iran claims the field partially extends into Iranian territory and asserts that Tehran should be a stakeholder in its development.

    One source said: “Developing this gas field in the waters so close to Iran will be impossible in the current security environment.

    “Everyone is expecting extended delays to progress on this project and all related projects, such as the planned onshore processing facility in Kuwait.

    “The offshore elements of the project would be especially vulnerable to attacks from Iran and there are likely to be security concerns over the development of this field for some time to come.”

    In July last year, MEED reported that KGOC had initiated the project by launching an early engagement process with contractors for the main engineering, procurement and construction tender.

    France-based Technip Energies completed the contract for the front-end engineering and design.

  • Sharakat plan signals next phase of Saudi water expansion

    10 March 2026

     

    Sharakat, formerly Saudi Water Partnership Company, released its latest seven-year statement in March, outlining the next phase of the kingdom’s water infrastructure plans.

    According to the document, desalination capacity from Sharakat-procured projects is expected to rise from about 3.88 million cubic metres a day (cm/d) in 2025 to roughly 7.18 million cm/d by 2031, reflecting the continued reliance on desalinated water to meet rising urban demand.

    The expansion will be supported by seven additional independent water plants (IWPs) with a combined capacity of about 2.8 million cm/d, alongside projects already operating, under construction or in procurement.

    Against this backdrop, 2025 proved to be the busiest year for desalination awards since before the Covid-19 pandemic. Total water infrastructure awards also remained strong at $10bn, despite dipping on the two previous years.

    Desalination projects accounted for $2.2bn across four schemes. The largest award was the $700m Shoaiba 6 seawater reverse osmosis (SWRO) desalination plant, which will have a capacity of 500,000 cm/d.

    Another key development came when Sharakat awarded the contract to develop the Ras Mohaisen IWP on the Red Sea coast.

    The project will treat 300,000 cm/d of seawater using reverse osmosis technology and will supply areas including Mecca and Al-Bahah. The developer consortium is led by Acwa Power, which holds a 45% stake, alongside Haji Abdullah Ali Reza & Partners with 35% and Al-Kifah Holding with 20%.

    Transmission projects

    Large transmission infrastructure continues to move forwards, with new contracts reaching $6.2bn in 2025, more than 60% of total awards.

    This includes a contract with Sharakat to develop and operate the kingdom’s second independent water transmission pipeline (IWTP) project. The winning consortium comprises local firms Aljomaih Energy & Water, Nesma Company and Buhur for Investment Company.

    The 587-kilometre (km) pipeline, capable of transporting 650,000 cm/d of water, will link Jubail in the Eastern Province with Buraydah in the Qassim region. Construction is expected to begin in the second quarter of 2026.

    In December, local firm Vision Invest was named as the preferred bidder to develop and operate the 859km Riyadh-Qassim IWTP, Sharakat’s third IWTP project.

    Vision Invest’s offer to develop the project with a levelised tariff of SR2.627 ($0.70) a cubic metre was almost 20% lower than the next nearest bidder

    Further transmission projects are also advancing through Saudi Arabia’s Water Transmission Company (WTCO). 

    Bidding opened in September for the Jubail-Buraydah transmission scheme and the Ras Mohaisen-Baha-Mecca independent water transmission system, which together will deliver more than 1.38 million cm/d of water across central and western Saudi Arabia. An initial deadline was set for the end of the year, although this has been extended several times.

    WTCO has also issued a tender for the construction of a $700m IWTP project in Qassim, including a 350km water transmission pipeline and 11 storage tanks. The main contract bids are expected in the coming weeks.

    Storage and wastewater treatment

    Saudi Arabia’s national water strategy aims to build reserves equivalent to seven days of municipal demand, requiring more than 115 million cubic metres of storage capacity by 2030.

    Alongside this, Sharakat’s seven-year plan envisages wastewater treatment capacity rising from 1.79 million cm/d to about 3.19 million cm/d.

    In February, a consortium of Saudi utilities provider Marafiq, the regional business of France’s Veolia and Bahrain/Saudi Arabia-based Lamar Holding reached financial close on a $500m wastewater treatment plant in Jubail Industrial City 2

    The project will be developed under a concession-style model similar to a public-private partnership, with the developer consortium responsible for building and operating the plant over a 30-year period.

    Some developers have also started to return to the Saudi water market, with Metito CEO, Rami Ghandour, explaining: “We took a break for a few years from bidding for municipal projects in the kingdom as we felt the market was overheating.”

    A consortium of Metito, Etihad Water & Electricity (EtihadWE) and SkyBridge was named the preferred bidder for the Hadda independent sewage treatment (ISTP) in December with a levelised tariff of SR2.354 ($0.63) a cubic metre.

    Meanwhile, a group comprising Miahona, Marafiq and Buhur for Investment Company was selected as the preferred bidder for the Arana ISTP with a levelised tariff of SR1.35 ($0.36) a cubic metre. Both the Hadda and Arana ISTP projects in Mecca Province are set to reach financial close this year.

    Outlook

    The project pipeline suggests that large transmission projects will continue drive contract activity. About $9.3bn of projects are currently under bid evaluation, with water pipeline schemes accounting for more than half, while a further $12bn of projects are in prequalification.

    The request for proposals has already been issued for the Riyadh East ISTP, which will have a treatment capacity of 200,000 cm/d in its first phase, expanding to 400,000 cm/d in the second phase. The bid submission deadline is 2 April.

    On the desalination front, IWP schemes at Ras Al-Khair, Tabuk, Shuqaiq and Jizan, have seen shifts in expected procurement timelines following earlier prequalification rounds.

    The largest of these is phase two of the Ras Al-Khair IWP, which has been in development for more than a decade and involves the construction of a 600,000 cm/d reverse osmosis desalination plant.

    According to the revised timeline, the $400m Al-Shuqaiq 4 IWP project will be the first of seven planned IWPs to reach commercial operations in 2029. The main contract is set to be tendered later this year.

  • Ruwais industrial complex struck by drones

    10 March 2026

    Register for MEED’s 14-day trial access 

    Abu Dhabi authorities are responding to a fire that has broken out at a facility in Ruwais industrial complex, caused by a drone attack.

    The Ruwais industrial complex, located in Abu Dhabi's Al-Dhafra region, houses the world's fourth-largest single-site oil refinery and is operated by Abu Dhabi National Oil Company (Adnoc).

    No injuries have been reported at this time, the Abu Dhabi Media Office said.

    The UAE continues to intercept drones and missiles fired from Iran, as attacks on the Gulf countries continue for a 11th day in the ongoing regional conflict.

    Apart from the Ruwais refining complex, which has a capacity of 922,000 barrels a day (b/d) of crude oil and condensates, Ruwais industrial complex is also home to petrochemicals producer Borouge’s main production complex.

    Additionally, Adnoc is in an advanced stage of engineering, procurement and construction (EPC) on a liquefied natural gas (LNG) project within the Ruwais industrial complex, which will have the capacity to produce about 9.6 million tonnes a year (t/y) of LNG from two processing trains, each with a capacity of 4.8 million t/y. When the project is commissioned, which is due to take place in 2028, Adnoc’s LNG production capacity will more than double to about 15 million t/y.

    Separately, Taziz – a 60:40 joint venture of Adnoc Group and Abu Dhabi’s industrial holding company ADQ – is overseeing the development of at least seven specialty chemicals plants in its planned derivatives zone in Ruwais Industrial City.

  • Contractors submit bids for Dorra offshore gas project packages

    10 March 2026

     

    Contractors have submitted bids to Al-Khafji Joint Operations (KJO) for engineering, procurement and construction (EPC) works on a project to develop natural gas from the Dorra gas field, located in the waters of the Saudi-Kuwait Neutral Zone.

    KJO, which is jointly owned by Saudi Aramco subsidiary Aramco Gulf Operations Company and Kuwait Petroleum Corporation (KPC) subsidiary Kuwait Gulf Oil Company (KGOC), has divided the project’s scope of work into four EPC packages – three offshore and one onshore.

    Indian contractor Larsen & Toubro Energy Hydrocarbon (L&TEH) has won package one of the Dorra facilities project, which covers the EPC of seven offshore jackets and the laying of intra-field pipelines. The contract awarded by KJO to L&TEH is estimated to be valued at $140m-$150m, MEED reported in October.

    Contractors submitted bids for the remaining three packages – offshore packages 2A and 2B and onshore package three by the final deadline of 9 March, according to sources.

    Two consortiums of contractors submitted bids for the packages, sources told MEED:

    • NMDC Energy (UAE) / Hyundai Heavy Industries (South Korea)
    • Saipem (Italy) / Larsen and Toubro Energy Hydrocarbon (India)

    KJO had extended the bid submission deadlines for these packages several times since last year.

    The EPC scope of work for package 2A includes Dorra gas field wellhead topsides, flowlines and umbilicals. Package 2B involves the central gathering platform complex, export pipelines and cables. Package three includes the EPC of onshore gas processing facilities.

    Saudi Arabia and Kuwait are pressing ahead with their plan to jointly produce 1 billion cubic feet a day (cf/d) of gas from the Dorra gas field.

    The two countries have been producing oil from the Neutral Zone – primarily from the onshore Wafra field and offshore Khafji field – since at least the 1950s. With a growing need to increase natural gas production, they have been working to exploit the Dorra offshore field, understood to be the only gas field in the Neutral Zone.

    Discovered in 1965, the Dorra gas field is estimated to hold 20 trillion cubic metres of gas and 310 million barrels of oil.

    The Dorra facilities scheme is one of three multibillion-dollar projects launched by subsidiaries of Saudi Aramco and KPC to produce and process gas from the Dorra field that has advanced in the past few months.

    AGOC onshore Khafji gas plant

    AGOC has set a current bid submission deadline of 22 April for seven EPC packages as part of a project to construct the Khafji gas plant, which will process gas from the Dorra field onshore Saudi Arabia.

    MEED previously reported that AGOC issued main tenders for the seven EPC packages in 2025. Contractors were initially set deadlines of 24 October for technical bid submissions and 9 November for the submission of commercial bids, which was then extended by AGOC until 22 December.

    The seven EPC packages cover a range of works, including open-art and licensed process facilities, pipelines, industrial support infrastructure, site preparation, overhead transmission lines, power supply systems and main operational and administrative buildings.

    France-based Technip Energies has carried out a concept study and front-end engineering and design (feed) work on the entire Dorra gas field development programme.

    Progress has been hampered by a geopolitical dispute over ownership of the Dorra gas field. Iran, which refers to the field as Arash, claims it partially extends into Iranian territory and asserts that Tehran should be a stakeholder in its development. Kuwait and Saudi Arabia maintain that the field lies entirely within their jointly administered Neutral Zone – also known as the Divided Zone – and that Iran has no legal basis for its claim.

    In February 2024, Kuwait and Saudi Arabia reiterated their claim to the Dorra field in a joint statement issued during an official meeting in Riyadh of Kuwaiti Emir Sheikh Mishal Al-Ahmad Al-Jaber Al-Sabah and Saudi Crown Prince and Prime Minister Mohammed Bin Salman Bin Abdulaziz Al-Saud.

    Since that show of strength and unity, projects targeting the production and processing of gas from the Dorra field have gained momentum.

    KGOC onshore processing facilities

    KGOC has initiated early engagement with contractors for the main EPC tendering process for a planned Dorra onshore gas processing facility, which is to be located in Kuwait.

    KGOC is at the feed stage of the project, which is estimated to be valued at up to $3.3bn. The firm is now expected to issue the main EPC tender within the first quarter of this year, MEED recently reported.

    The proposed facility will receive gas from a pipeline from the Dorra offshore field, which is being separately developed by KJO. The complex will have the capacity to process up to 632 million cf/d of gas and 88.9 million barrels a day of condensates from the Dorra field.

    The facility will be located near the Al-Zour refinery, owned by another KPC subsidiary, Kuwait Integrated Petroleum Industries Company.

    A 700,000-square-metre plot has been allocated next to the Al-Zour refinery for the gas processing facility and discussions regarding survey work are ongoing. The site could require shoring, backfilling and dewatering.

    The onshore gas processing plant will also supply surplus gas to KPC’s upstream business, Kuwait Oil Company, for possible injection into its oil fields.

    Additionally, KGOC plans to award licensed technology contracts to US-based Honeywell UOP and Shell subsidiary Shell Catalysts & Technologies for the plant’s acid gas removal unit and sulphur recovery unit, respectively.
