Comet Ridge (COI) has completed a multi-zone stimulation program at its Albany 2 well as it tests the commercial capability of its two “deeps sandstone” wells in the Galilee Basin.
Three prospective sandstone reservoir zones in the mid to upper portion of the Lake Galilee Sandstone sequence were treated with large volumes of sand and ceramic proppant.
This marks the first-ever attempt to stimulate the specific sandstone in the Galilee Basin and shows that these sands are high-grade stimulation candidates.
The company decided not to place a slightly deeper treatment as an injectivity test showed the treating pressure would go above the pressure rating for the wellhead.
In future Albany wells, a higher pressure rated wellhead can be used.
At this stage, the liquid used to carry the proppant into the reservoir currently being flowed back to storage tanks.
This will be followed by the well being further flowed with the assistance of nitrogen to lift the liquid stream from the well. It’s expected this will occur for the next few days.
During the month of January, a work-over rig will arrive to run a 2-3/8 inch diameter production tubing string into the well. This should set the well up to allow for longer term production testing.
The stimulation equipment has now been moved seven kilometres northwest to the Albany 1 well where it will undertake a planned four stage stimulation following the return of the Condor Energy Services crew after the Christmas and New Year break.
Albany 1 is expected to receive similar sand and ceramic proppant into four sandstone reservoir zones throughout the well and, similarly to Albany 2, will be flowed back to tanks before the work-over rig arrives to run the production tubing string.
Once the wells have been completed with production tubing, the scheduled production testing program will begin.
Shares remain flat and trading for 19 cents each at market close.
