Oman’s PDO receives proposals for planned EPC framework

1 July 2025

Petroleum Development Oman (PDO) has received proposals from contractors for a proposed pool of contractors to which it will tender engineering, procurement and construction (EPC) works on its greenfield and brownfield projects at its Block 6 concession in the sultanate.

Majority state-owned PDO intends to sign framework agreements with selected contractors that will be invited to participate in the tendering process for two categories of projects, known as Wave 1 and Wave 2.

The structure of the proposed contractors’ group will be similar to the Long-Term Agreement pool of EPC service providers that Saudi Aramco operates for its offshore and onshore projects, it was previously reported.

Contractors submitted proposals to PDO for the proposed EPC framework agreement by the deadline of 22 June, sources told MEED.

PDO floated a prequalification document on 17 April, detailing its requirements, criteria, planned projects and other aspects of the EPC framework agreement.

The oil and gas producer set an initial deadline of 8 May for submission of proposals, which it then extended until 15 June, and eventually until 22 June.

The projects earmarked by PDO for the Wave 1 and Wave 2 categories are as follows:

Wave 1:

Al-Ghubar GOGD project – Oil and gas

The Al-Ghubar Gas-Oil Gravity Drainage (GOGD) project is located in Qarn Alam, in the northern area of PDO’s Block 6 concession. The scope of the project is to build a new facility. The production from this facility will be exported to the main oil line. The Al-Ghubar GOGD facility will be designed as a sour facility (hydrogen sulfide) to handle a maximum oil production of 1,800 standard cubic metres a day (cm/d), a maximum total water flow rate of 10,421 standard cm/d and a maximum gas lift of 256,934 standard cm/d.

Raba hub development – Oil

The Raba hub project is part of the Qarn Alam growth development located in the northern area of the PDO concession. The strategy encompasses fields in the nearest surrounding area, the Raba Infill and Raba East fields. The production from Raba Infill will be directed to the existing Raba gathering station (RGS) and the production from the Raba East field will be directed to the newly proposed Raba hub station (RHS). With the additional production from Raba Infill to RGS, some modifications to the RGS are also proposed. For better operational flexibility, interconnection between the existing RGS and the new RHS facility is also proposed, to accelerate an estimated 176 million barrels of unconventional reserves and accelerate production growth by adding an additional 50,400 barrels a day (b/d) of output by 2029.

Rabab Harweel Integrated Project (RHIP) tranche 2 – Oil and gas

The RHIP involves miscible gas injection across multiple fields, subdivided into two tranches. Scheduled to come on-stream starting in 2028, tranche two aims to expand oil production capacity in existing fields and enhance gas injection into these fields. The scope also includes sustaining gas supply from the gas reservoir by installing a depletion compression facility and expanding the off-plot gas supply network.

Wave 2:

Nimr NRPS atmospheric pressure flare recovery – Gas

The EPC of microturbine, gas sweetening and gas compression facilities.

Dulaima carbon dioxide-based enhanced oil recovery – Carbon capture, utilisation and storage (CCUS)

A processing facility to handle the incremental hydrocarbons and carbon dioxide (CO2) volumes, including CO2 recycle injection.

Wadi Umairi development – Oil and gas

Oil and gas processing facilities, such as separators, tanks, water injection pumps, gas sweetening unit, off-plot network and utilities.

Makarem development project – Sour gas

A greenfield sour gas facility involving gas sweetening and sulphur recovery.

Bout full field development project – Oil and gas

RMSs and a gathering station, multiport selector valves, water injection manifolds, separators, hydro-cyclone package, water injection pump and utility units.

Burhan NW depletion compressor – Gas

Inlet separators, air coolers, depletion compression, condensate pumps, electrical infrastructure and utilities.

Makarem full development project – Sour oil

A gathering station, RMSs, water injection, manifold, pumps, separators and utility units.

Therm NMT ALSE development – Sour gas

OTSGs, cyclic steam stimulation wells, manifolds skids, CS production/steam headers, splitter, air coolers and export pumps.

PDO is the operator of the Block 6 hydrocarbons concession in Oman, which is the sultanate’s largest and most prolific concession. Situated onshore and covering an area of 75,119 square kilometres, Block 6 contains 202 oil fields and 43 gas fields.

The Omani government holds a 60% stake in PDO, with the other shareholders being UK-based Shell (34%), France’s TotalEnergies (4%) and Thai state-owned PTTEP (2%).
