Sacramento Basin-focused natural gas developer and producer, Sacgasco Limited has advised that the Dempsey 1-15 well in the Sacramento Basin in California is drilling ahead in the 8 ½ in. vertical hole.
During drilling, well-mud weights have been increased regularly to 13.5 ppg to control increasing levels of background gas. Multiple zones of significantly higher than background gas shows have been encountered while drilling.
The best zone of gas shows had a gas level of over 500 times the background gas.
Shareholders and investors are advised that the significance of these shows will become more apparent when the next wireline logs are run to full evaluate the intersected gas shows and reservoirs. This is planned after reaching the proposed total drilling depth of approximately 3200 m.
The Dempsey 1-15 well is currently drilling ahead at 2070 m (~6800 ft) to the highly under-explored deeper targeted reservoirs in the remaining 1000 m (~3200 ft) of section to be drilled.
Sacgasco is drilling the largest undrilled mapped structural closure in the northeastern part of the prolific Sacramento Gas Basin and is interpreted to be optimally located to trap gas migrating out of gas generating areas located to the west and south.
After Farm-in Working Interests in the Dempsey Gas Project:
- Sacgasco Limited (operator): 50%
- Empyrean Energy PLC: 30%
- Pancontinental Oil and Gas NL: 10%
- Xstate Resources Limited: 10%
Sacgasco Managing Director Gary Jeffery commented:
“We are very pleased with the execution of the drilling to date. The results have been broadly consistent with prognoses. Further updates will be provided on meaningful results from the evaluation of the target sandstone reservoirs spread across the interval to be drilled.”
