State-upstream operator, Kuwait Oil Company (KOC) has extended the bid deadline by a month for two major upstream oil deals.

The first is an estimated $2bn deal to build three new oil and gas gathering centers in the north of the country. Priced bids are now due on 22 December, instead of 10 November. Twelve engineering, procurement and construction (EPC) firms have been prequalified for the deal:

KOC set the same deadline for another project, which covers the construction of a new effluent water treatment and injection plant, also in northern Kuwait. The original deadline was 17 November. Most of the same firms are prequalified to bid on both projects.

Kuwait’s oil fields are connected to 26 gathering centres, which serve as a collection location for crude oil produced at several wells connected by flowlines, providing initial treatment through the separation of associated gas and removing salt.

The water project aims to provide pressure support for the Sabriya and Raudhatain fields in the north of Kuwait by the end of 2017, by injecting as much as 500,000 barrels a day (b/d) of treated effluent water from four oil-gathering centres in the area.
