The Morris #12-4 well, located in the West Grimes Gas Field, Colusa County, California, was drilled to a depth of 8,007 feet and encountered approximately 115 feet of potential gross gas pay in several intervals in the Forbes formation. Several of these intervals were perforated and tested gas on a 1/4-inch choke at a stabilized flow rate of 500 MCFPD. The shut in tubing and shut in casing pressures were 3,150 psig. Aspen has a 21% operated working interest in this well.
This was the sixteenth successful gas well out of sixteen attempts by Aspen in this field. Aspen is currently drilling the Harlan #1-24 well, also located in this field. Aspen is also in the initial permit phase of a 10 square mile 3-D seismic survey in this area in which Aspen owns a 32% operated working interest.
The Malibu #1, a 4,200-foot Kione gas test, located in Glenn County, CA, was recently drilled and plugged and abandoned.
In the Sacramento Valley, Aspen has drilled 36 successful gas wells out of 39 attempts during the last 3 1/2 years (92% success rate) and drilled 44 successful gas wells out of 51 attempts during the last 5 1/2 years, a success rate of 86%. Aspen currently operates 62 gas wells and has non-operated interests in 21 additional wells in the Sacramento Valley of northern California and has non-operated interests in approximately 33 oil wells in Montana.
