Baku: bp has successfully completed its first pressure coring acquisition in the Azeri-Chirag-Gunashli (ACG) field, marking a significant advancement in core sample collection technology, as reported by Trend News Agency.

According to Trend News Agency, the operation used innovative pressure coring technology for the first time not only in the Caspian region but also across bp’s global operations. The goal of this technology is to obtain core samples under in-situ reservoir conditions, which helps to minimize fluid loss and core damage. The core samples acquired from the ACG Balakhany reservoir will undergo various laboratory tests to reduce uncertainties about residual oil saturation under water flood conditions. This data is crucial as it will guide the enhancement of oil recovery methods and aid in the planning and predictability of future developments in Balakhany reservoirs.

The pressure core acquisition took place in the Balakhany VIII formation via a newly drilled well in West Azeri. During this proc
ess, bp successfully recovered four fully pressurized core samples with all fluids captured and preserved in their original condition. These samples, along with on-site analysis data, have been sent for further laboratory examination. The insights gained from this core and fluid data are expected to enhance the understanding of the subsurface conditions behind the water flood, thereby allowing bp to select the most effective resources development strategies.

The Azeri-Chirag-Gunashli field has been under development since September 20, 1994, with the project slated to continue until December 2049. The field is estimated to contain about 1 billion tons of oil. The current shareholders of ACG include bp with a 30.37 percent stake, SOCAR at 25 percent, MOL Group at 9.57 percent, INPEX at 9.31 percent, Equinor at 7.27 percent, ExxonMobil at 6.79 percent, TPAO at 5.73 percent, ITOCHU at 3.65 percent, and ONGC Videsh Limited (OVL) at 2.31 percent.
