Champagne Creek-3 tests positive but remedial work needed

TESTS of a 570-metre gas zone at Champagne Creek-3 have produced gas flow rate estimates of betwe...

The well has been shut-in with plans for an extended well test and samples have been taken for compositional analysis.

Sunshine said these results were encouraging for the potential development of shallow reservoirs at Champagne Creek, but poor cementing of the casing resulted in water production along with the gas and gas rates could not be accurately measured.

The well released completion fluid without assistance, and gas and water flowed for about four hours before the shut-in for an extended pressure build-up, Sunshine said.

After a shut-in of about 20 hours the wellhead pressure was at 870 psi.

Before the well was completed, logs showed no cement bonding over the target gas zone and this indicated the zone was not isolated, Sunshine said.

A remedial cement job was attempted to isolate the target gas interval from water sources, but follow-up measurements indicated that 100% zonal isolation was not achieved.

Sunshine is now preparing a plan for further well testing to measure gas and water rates and to determine the reservoir’s properties.
