Hurricane Energy has shut-in considered one of two wells on the Lancaster Early Production System (EPS), situated within the West of Shetland space, attributable to interference between two producing wells. As a outcome, Hurricane has suspended its full-year manufacturing steerage.
The Hurricane-operated Lancaster area is now in its first part of growth, the EPS, consisting of two wells tied again to the Aoka Mizu FPSO vessel. The first oil was achieved in June 2019.
Hurricane has been finishing up ongoing testing of the 2 Lancaster EPS wells as a way to decide the sustainability of mixed manufacturing charges as much as gross 20,000 bopd.
In an replace on Friday, Hurricane mentioned that attaining this goal price at a sustainable degree has not been doable because the impression of accelerating manufacturing charges resulted in instability within the movement regime on the 205/21a-7Z effectively because of interference between the wells.
This has led to a choice to shut-in the 205/21a-7Z effectively in the meanwhile and return to a interval of testing most sustainable charges from simply the 205/21a-6 effectively.
The water manufacturing from the 205/21a-7Z effectively on the time the instability was skilled was in keeping with the water manufacturing that had been seen over the earlier weeks.
The Lancaster EPS is at present producing from the 205/21a-6 effectively at a price of roughly 10,300 bopd.
The firm plans to extend this price incrementally, to find out its most sustainable degree.
This course of will lead to a interval of manufacturing considerably under ahead steerage of web 18,000 bopd and Hurricane is, subsequently, suspending earlier full-year steerage of web 17,000 bopd.
Production has averaged 15,500 bopd yr thus far.
Dr Robert Trice, Chief Executive of Hurricane, commented: “The outcomes of the current testing of the Lancaster EPS wells at elevated mixed manufacturing charges are disappointing and the diploma of interference encountered is surprising.
“Whilst the wells present excessive productiveness individually, their proximity and related interference behaviour require additional knowledge acquisition earlier than the corporate could be assured about optimum long-term effectively charges. This newest growth reinforces that.
“This knowledge acquisition course of continues, and additional updates can be supplied as soon as we’ve got decided our goal plateau manufacturing price with the present effectively configuration”.
