The Marjan oil and gas field is situated in the Arabian Gulf, off the eastern coast of Saudi Arabia.
Owned and operated through Saudi Arabia’s state-owned oil and gas company Saudi Aramco, the offshore field is currently undergoing spread under the Marjan Crude increase Programme published in 2017.
The detail of programme target to increase the crude production capacity of the field by 300,000 barrels per day (BPD) and output 360,000bpd of ethane and natural gas liquids (NGL) by processing an additional 2.5 billion standard cubic feet per day (Bscfd) of gas generated from the field.
The Marjan Crude Increment Programme is being implemented via multiple work packages, with an estimated entire investment of $12bn. The offshore work packages are valued at $5bn, while the onshore package is estimated to cost up to $7bn.
The Marjan field detailed project forms part of Saudi Aramco’s $18bn investment programme for increase the production capacity of the Marjan and Berri offshore fields, by 550,000BPD of crude oil and 2.5 billion standard cubic feet per day (BSCFD) of gas.
The Marjan field is expected to reach its extended crude oil production capacity of 800,000 BPD in 2022.
Marjan oil field scope:
Marjan Crude oil Increment Programme comprises the development of an offshore GOSP, named Marjan GOSP-4, within 10km of the GOSP-2 and GOSP-3 facilities, and 24 oil, water, and gas injection platforms.
The offshore detail also comprises additional tie-in platforms, production decks, subsea export, and estate pipelines, as well as the replacement of decks of two existing tie-in platforms, the replacement of existing gas turbine generators, and the establishment of two 115kV subsea power and communication cables.
The onshore element of the project involves the elaboration of the Tanajib processing complex, with the addition of a gas plant. It also comprises a new NGL recovery and fractionation facility and additional gas compression facilities.
even, a water desalination facility and a co-generation facility are planned to be constructed as part of the project.
McDermott was awarded two engineerings, procurement, construction and installation contracts for the Marjan field spread project in July 2019.
The first EPCI agreement award for the Marjan GOSP-4 that McDermott got in consortium with China Offshore Oil Engineering Company (COOEC) is worth $3bn.
The second agreement is to value $1.5bn. It was awarded to McDermott and is for three tie-in platforms, seven wellhead platforms, and the installation of subsea trunk lines and in-field pipelines of a total distance of 540km.
Saipem secured the EPCI agreement for new gas treatment and sulfur recovery units at the Tanajib onshore processing facility for the Marjan increment project in July 2019.
In January 2019, Saipem awarded another EPCI contract for the subsea systems of the Marjan oil field expansion, including new platform decks and jackets, as well as the subsea cables and umbilicals.
Sinopec Engineering was an agreement for two pipeline projects for the Marjan field expansion in July 2019.
In the same month, L&T Hydrocarbon Engineering (LTHE) was awarded a contract for four tie-in platforms, one tie platform module, and nine production deck modules, as well as 217km of subsea pipelines and 145km of subsea cables.
WorleyParsons got the front-end engineering and design (FEED) services contract for the project in July 2017.
