Oil and gas exploration firm PA Resources has hailed the long-term drill stem test at the Diega 1-8ST well in Equatorial Guinea a success.
The firm said the test at the Diega accumulation in the country’s Block 1, which PA Resources has a 5.7% working interest, was now complete and the Atwood Hunter rig had been released.
The firm said the well had encountered a good quality oil pay, establishing the deepest known oil on the Diega accumulation. While, testing of a planned horizontal sidetrack suggested rates up to around 7,300 barrels of oil per day.
PA said the well had been suspended for re-use as a future production well. The firm said submission of a Diega plan of development is expected this year, targeting first oil in 2016 via a subsea tieback to the Aseng FPSO.
“This is an excellent result in every respect; well productivity, reservoir quality, field continuity and the size of the accumulation,” said chief executive Mark McAllister.
“An early Diega development is facilitated by the existing infrastructure in Block 1, and we expect that any development will be expandable to accommodate additional reserves identified during further appraisal drilling.”
