History

ROC farmed in to a Production Sharing Contract which includes the three fields, effective 1 January 2014 until December 2034.  The PSC terms are designed for field redevelopment and enhanced oil recovery to commercially encourage progressive incremental oil development.

The first phase of redevelopment activities was completed in 2015/16 with 4 wells drilled, well interventions and facility debottlenecking projects completed.

The next phase of redevelopment included four infill production wells in D21 and seismic acquisition in  in 2017.

Redevelopment activities continued in 2018 with completion of three wells at J4.  A D35 drilling campaign of 10 wells was successfully completed from August 2018 to August 2019.  A 4-well drilling project at D35-B platform was completed from November 2019 to April 2020.

A D21 redevelopment project of 6 wells was completed from October 2020 to April 2021. To accommodate the new wells, a deck extension with 3 new conductor slots was completed in 2019.

Currently pursuing further drilling opportunities.

Geologically, the Fields lie within the western Balingian province of the Sarawak Basin.
