ExxonMobil started production Friday at the $2.5 billion Tapis enhanced oil recovery (EOR) project offshore Terengganu, Malaysia.

ExxonMobil is partnered with Malaysia’s Petronas for the project. Each company holds a 50 percent participating interest.

The Tapis EOR will utilize a water-alternating-gas process to recover the remaining oil reserves from the Tapis field by gradually sweeping the oil to producing wells. The process will increase overall recovery at the field.

Operations began with water-alternating-gas injection into targeted wells on the Tapis A platform from the Tapis R central processing platform Friday.

The facility has 31 miles of in-field pipelines and undersea cables to enable gas and water injection and full well stream production from the existing Tapis platforms and to export production from Tapis R.

The Tapis R central processing platform has a 390 million cubic feet per day gas compression capacity and 270,000 barrels per day water injection facilities.

Modifications and retrofit work on the existing Tapis platforms will continue including upgrades and well-work restoration to expand water-alternating-gas process coverage to the entire Tapis field.
