Cequence gauges Alberta Falher gas-liquids discovery

Cequence Energy Ltd., Calgary, has gauged a gas-liquids discovery in northwestern Alberta that the company said validates a 20-section geological prospect previously defined by well control and confirmed by 3D seismic on company lands.

The Cequence operated 16-18-61-01w6 well at Simonette/Resthaven, southeast of Grande Prairie, Alta., went to 4,550 m measured total depth including 1,589 m of horizontal section in the Falher formation.

The well flowed on clean-up for 119 hr at a final rate of 14 MMcfd with 1,850 psi flowing tubing pressure through a 15.9-mm choke after fifteen 55-tonne fracs placed using a frac port system and slick water. Natural gas liquids yield is expected to be 20 bbl/MMcf.

The discovery, flow tested to sales through the Cequence-owned Simonette gathering system, was drilled as a farm-in commitment well, and Cequence retains a 65% working interest.

Based on publicly available data, the analog pool at Musreau/Kakwa 20 miles to the northwest is estimated to be producing more than 60 MMcfd of gas from 21 horizontal wells drilled on a typical spacing of two wells per section. Cequence believes that the Simonette/Resthaven pool is likely similar to the Musreau/Kakwa pool in terms of reservoir quality, thickness, and pressure and may provide a model for expected results once more production history is available.

The 16-18 well cost $6.6 million to drill and complete, and well costs are expected to decrease as the pool is developed.

Cequence noted that the Falher potential adds to the already extensive Montney, Wilrich, and Dunvegan resource opportunities identified on Cequence’s 220-section Simonette land base.
