Shell calls for bid St Joseph CEOR Pilot Vessel project
The international oil company (IOC) Royal Dutch Shell is calling for bid a three year engineering contract to design and develop a pilot vessel to provide chemical enhanced oil recovery (CEOR) at the St Joseph oil field offshore the State of Sabah in Malaysia.
This quick move comes as the consequence of the decision made by the national oil company (NOC) Petronas to drop its Angsi CEOR Vessel project and consider alternative options.
In January 2012, Shell and Petronas signed two production sharing contracts (PSC) for enhanced oil recovery (EOR) projects offshore the coast of Sabah and Sarawak States in Malaysia.
With $12 billion capital expenditure over the next 30 years, Shell and Petronas are targeting to increase the current 35% recovery rate to 50% in nine fields of the Baram Delta and four other fields offshore Sabah including St Joseph.
In parallel Petronas initiated the Angsi CEOR Vessel project to be moored 160 kilometers offshore Terengganu in the Malaysia Peninsula.
Budgeted to $1 billion capital expenditure, Petronas Angsi CEOR Vessel intended to inject a combination of desalinated water together with an alkali-surfactants-polymers (ASP) mixture.
In this process the oil and gas recovery performances are directly related to the adequate balance between the desalinated soft water and the surfactant additives.
According to Shell and Petronas agreement the vessel developed and used for Angsi CEOR was expected to move to St Joseph after four years operations.
Unfortunately, in moving into execution phase, the last costs estimates for the Angsi CEOR Vessel were exceeding significantly the $1 billion budgeted costs leading Petronas to consider alternative options.
Technip completed St Joseph CEOR conceptual study
In this context, Shell speed up the development of the St Joseph CEOR Vessel project.
Defined as a pilot, St Joseph CEOR Vessel should be far smaller than Angsi.
From the conceptual study performed by Technip Kuala Lumpur, St Joseph CEOR should have 2,500 barrels per day (b/d) injection capacities instead of 150,000 b/d for Angsi.
St Joseph CEOR topsides should not exceed 500 tonnes while Angsi was spiraling up to 7,000 tonnes.
Because of its limited size, Shell intends to develop St Joseph CEOR Pilot project based on a converted barge.
Shell qualified 10 engineering companies to bid on this St Joseph CEOR Pilot project.
The scope of work includes the detailed design of the St Josepth CEOR Pilot project as well as three years engineering contract for process continuous improvement while in operations.
In this scenario,Shell is planning to award St Joseph CEOR Pilot project engineering contract on the first quarter 2014 for a first injection on test offshore Sabah, Malaysia, in 2015.
