Crosgan appraisal well encounters gas
- Exploration & Production
Sterling Resources Ltd., a Canada-headquartered oil and gas company, has announced that the Crosgan gas discovery appraisal well 42/15b-3 in the UK Southern North Sea, will be plugged.
The well, operated by RWE Dea, and drilled by the Ensco 70 jack-up drilling rig, has reached a total depth of 8401 feet measured depth and has encountered gas bearing sands in the Carboniferous Yoredale Formation with 35 feet of pay in the targeted Whitby Sandstone and a further 26 feet of pay in various shallow sands within the overlying upper Carboniferous section.
The well has encountered a gas-down-to (GDT) deeper than the gas-water contact observed in the offset 42/10b-2z well drilled in 1995.
The Whitby formation, however, was encountered 265 feet deep to prognosis and the sand thickness is less than expected for the well.
On completion of logging activities currently in progress, the well will be plugged and abandoned. Sterling Resources UK plc holds a 30% interest in the Crosgan Licence.
