Paul Graham Drilling wins contract for Sacgasco’s Dempsey 1-15 well


Paul Graham Drilling has secured a contract to drill Australian-based natural gas developer and producer Sacgasco’s Dempsey 1-15 well on the Dempsey appraisal and exploration project.

As part of the contract, signed with Sacgasco’s wholly owned US subsidiary Peoco, Paul Graham will deploy Graham Rig No 9 for drilling the well, which is scheduled to intersect seven or more conventional sandstone gas reservoir targets with a planned total depth of 3200m.

With a depth rating of up to 16,500ft, Rig 9 is a conventional, full view, box on box, triple drilling rig and has a 4.5in drillpipe.

Sacgasco operations vice-president Dero Parker said: “The Dempsey 1-15 well will be one of the most watched wells in the history of drilling in the prolific Sacramento Basin California.”

The drilling equipment is to be combined with a 10,000 psi well head and stack and expected to allow a wide range of outcomes from the under-explored primary sandstone targets in Dempsey.

"The Dempsey 1-15 well will be one of the most watched wells in the history of drilling in the prolific Sacramento Basin California."

Spudding on the Dempsey 1-15 well is scheduled later this month.

Comprising seven stacked conventional reservoir targets, Dempsey is a 1+ Tcf natural gas appraisal and exploration project.

Sacgasco expects to award additional drilling service and material supply contracts in the near future.

The company operates the well with a 50% working interest, while other stakeholders include Empyrean Energy with 30%, Xstate Resources with 10%, and Bombora with 10%.
