Conoco winter well results under review
ConocoPhillips says it drilled eight exploration and appraisal wells on the North Slope during this past winter’s off-road drilling season and tested six of those. The Alaska Oil and Gas Conservation Commission (and therefore Petroleum News) classifies all the wells as exploratory.
The two wells that were not tested was “due to end of winter season timing constraints,” company spokeswoman Natalie Lowman told Petroleum News June 3.
Interestingly, AOGCC shows a total of 11 exploration wells drilled this past winter by the company; completed between November and the end of the winter season in early May, with the first well in the Colville River unit’s Putu prospect from drillsite CD-4. That well was mentioned by ConocoPhillips Chairman and CEO Ryan Lance in an earnings strategy presentation last year.
When asked how soon well results would be released, Lowman said, “We will be evaluating results of the exploration season in the coming months. This winter we drilled eight exploration wells (two re-entries). … We also laid gravel for the GMT2 drilling pad.”
Last winter seven wellsIn last winter’s off-road season, ConocoPhillips conducted the largest exploration season on the North Slope to that point since 2002.
The company said four wells of its seven wells were drilled in and near ConocoPhillips’ behemoth Willow discovery at the western end of its recent finds and one slant and vertical well at the Putu prospect, directly south of the Colville unit.
A well was also drilled at the Stony Hill prospect, straight south of Putu 2.
The Putu wells successfully targeted two distinctive seismic amplitude anomalies, Scott Jepsen, ConocoPhillips Alaska vice president, said in September. There was a third anomaly in the Putu prospect, he said, immediately west of the two tested anomalies - that anomaly was drilled this winter from CD-4.
