Bittern B4Y intervention
In Q2 2019 the Bittern B4Y well was re-entered through use of a Light Well Intervention Vessel (LWIV). The planned work scope saw the shut off of water influx from a deeper part of the reservoir and perforation of the upper section to access undrained reserves. The operation was very successful being delivered safely on time and within budget.
Results from this intervention were at the upper end of expectations with a gross incremental production uplift to the Bittern field of approximately 5 kb/d. In collaboration with our joint venture partners, we are pursuing similar high value, low cost opportunities to maximise recovery from Bittern.
