Block Energy begins Georgia field redevelopment

Block Energy PLC Project II started its three-project redevelopment of the Patardzeuli Middle Eocene reservoir in Patardzeuli oil field, Block XIB, Georgia.

Well JSR-01DEEP will be drilled by September and will deepen existing well JSR-01 which was drilled by a previous operator in 2013. It is the first of a series of wells that will deepen or side-track the existing 50 legacy wells to develop areas of undrained oil, the company said.

The original JSR-01 well penetrated only the upper 55 m of the Middle Eocene reservoir which is over 600 m thick in Patardzeuli. JSR-01DEEP will target an undrained part of the Middle Eocene reservoir, with placement of the well-path guided by 3D-seismic data attributes that indicate a zone of fracture corridors. This strategy was employed successfully at JKT-01Z in West Rustavi-Krtsanisi field.

Block XIB covers 615 sq km and is Georgia's most productive block, with over 180 million bbl of oil produced from the Middle Eocene, peaking in the mid-1980s at 67,000 b/d (OGJ Online, Dec. 17, 2021). 2C contingent resources are 29 MMboe with 245 MMboe prospective resources.

Materials and equipment required for the drilling of JSR-01DEEP are in Georgia and preparatory operations have commenced.
