Calliope is a patented, breakthrough technology that removes liquids from "loaded-up" gas wells. Calliope is differentiated from other fluid lift technologies because it does not rely on reservoir pressure and has only one down-hole moving part. In many wells, Calliope can reduce reservoir pressure far below that achievable by other fluid lift technologies, thereby recovering substantial amounts of stranded gas reserves.
James T. Huffman, President, said, "Our Calliope technology has brought many totally dead gas wells back to life after they were given up on by other operators. Based on Calliope production alone, the previously dead Carroll well now ranks in the top 20% of all onshore U.S. gas wells. The Carroll well is just one example where Calliope brought a dead well back to life, creating significant value for our company."
"Calliope is a low cost, low risk technology that creates significant economic value," Huffman said. "Calliope has already created $7,000,000 to $8,000,000 of value on the Carroll well at today's natural gas prices, and it creates more value every day. Our average non-prototype Calliope installation is projected to recover about 1.0 Bcfg at an 'all in' (finding and lifting) cost of $0.95 to $1.00 per Mcfe. With Calliope's superb economics, it only takes a handful of wells to create $50,000,000 to $100,000,000 of incremental value."
The 11,800-foot Carroll well is located in Canadian County, Oklahoma and, together with a sister well, produced from the Morrow formation. In their prime, both were excellent wells. However, reservoir pressure eventually declined to the point where the Carroll well "loaded-up" with fluids and died. Other operators tried unsuccessfully to revive the well using conventional technologies such as compression, plunger lifts and siphon strings.
CREDO identified the Carroll well as a candidate for its Calliope system from public data. The Morrow formation had been dead for five years. A review of the records indicated that the sister well was a better Calliope candidate because the Carroll well had been subjected to a "parting shot" when the previous operator attempted to plug-off the Morrow formation and open a lower zone.
After an unsuccessful attempt to acquire the sister well for Calliope, CREDO purchased the Carroll well in 1999 for $25,000. Calliope was installed and it immediately returned the Carroll to production, making 650 Mcfd. In subsequent years, Calliope has made about 15,000 cycles to unload fluids from the Carroll wellbore. The well has responded by producing over 1.0 Bcfg to date, and is still producing about 200 Mcf per day. Total estimated Calliope reserves for the Carroll are 1.5 to 1.7 Bcf. By comparison, without Calliope, the sister well has produced only one-tenth as much gas in the same time frame.
Huffman further stated, "The Carroll well proves the technical and economic efficacy of Calliope. We have installed Calliope on many other wells that will also produce very significant amounts of natural gas. We estimate that there are thousands of wells that could benefit from Calliope today and thousands that will benefit in the future."
"We have three strategies to fully monetize our Calliope technology," Huffman said. "One is to drill new wells into old depleted fields and then use Calliope to recover the stranded gas. A separate press release will discuss our first such well. The second strategy is to purchase dead and uneconomic wells from outside parties. The third entails entering into joint ventures with outside parties that already own Calliope candidate wells. We are pursuing all of these strategies, and we are seeing increasing interest in Calliope from third parties."
"CREDO is a top performing company, making Forbes' list of the 'Best 200 Small Companies' for three out of the past six years; Fortune Small Business Magazine's list of the 'Fastest Growing Small Companies' in each of the last four years; USA Today's list of the '25 Best Companies of the Past 25 Years'; and John S. Herold's list of the most profitable oil and gas companies on a unit of production basis," Huffman said. "Our success with Calliope has made a very significant contribution to this record of excellence by generating about 25% of our proved developed reserves in only five years."
