Oil and gas development company Empyrean Energy has confirmed that initial flow testing of the second deepest zone of gas shows in the Dempsey 1-15 well in the Sacramento Basin, onshore California is now complete.
At the time of concluding the test, the zone flowed gas at a rate of around 140mcf/d with about 150 pounds per square inch (psi) of tubing pressure.
Once the test was completed, shut in tubing pressure increased to more than 6,000psi within 32 hours.
The company expects the zone to be a significant gas discovery.
Empyrean Energy CEO Tom Kelly said: “It is very early days in the testing of the Dempsey 1-15 well, and whilst the boom two zones have both flowed clean dry gas with very high down hole pressures, both zones exhibit tight permeability.
“The pressure and potential extent of gas reservoir are significant and every effort is being made to use industry best practices in order to see if we can stimulate the second deepest zone to achieve a much beer flow rate before moving up hole to test the next zones of interest.”

By GlobalDataIn order to improve the permeability in the vicinity of the wellbore and achieve greater connectivity to the zones immediately above and below, the partners are planning to fracture stimulate the zone.
With planning, design and the approval process underway, the well is set to be placed on production until the approvals are obtained and the well is ready to stimulate.
