Bechtel of the United States has been awarded a $1.458 billion (Dh5.35 billion) engineering, procurement and construction (EPC) contract by Abu Dhabi Gas Industries Ltd (Gasco) for its second package in the Onshore Gas Development (OGD-III) scheme.

It is the largest contract awarded this year in Abu Dhabi’s gas sector and paves the way to award the other four packages of the ambitious OGD-III scheme.

Bechtel undertook the front end engineering and design (Feed) for the full OGD scheme earlier.

“The letter of award was issued in Abu Dhabi on November 26 and the project will be managed from Bechtel’s offices in London. The project is scheduled for completion within 40 months including successful test runs,” a statement from Gasco said yesterday.

Package II of OGD-III will process 1,300 million standard cubic feet per day (scfd) of Thammama-F well fluid to produce 125,000 barrels per day (bpd) of condensates, 12,000 tonnes per day of natural gas liquids (NGL) that include about 3,200 tonnes per day of ethane.

It will also recycle an equal volume of produced gas into the reservoir via a high pressure gas injection system.

Foster Wheeler of the United Kingdom will act as project management consultant.
