Energean Oil & Gas PLC confirmed its best estimate of recoverable resources in its Karish North gas discovery offshore Israel with a sidetrack drilled 700 m north of the original hole.
The sidetrack encountered the gas-water contact at 4,791 TVD, 13 m below the gas-down-to depth of the original wellbore. A thin rim of light oil or condensate was identified immediately above the gas-water contact.
The appraisal confirmed a total mapped hydrocarbon column of 310 m.
Energean plans to develop the discovery, in more than 1,700 m of water, as a tie-back to a floating production, storage, and offloading vessel under construction to handle production from Karish and Tanin gas fields (OGJ Online, Apr. 16, 2019).
Energean’s best estimate for the resource is 1.3 tcf of gas initially in place, 900 bcf of recoverable gas, and 34.2 million bbl of recoverable liquids.
The Stena DrillMax drillship will next drill three Karish Main development wells.
