Particle Drilling Technologies Announces Commercial Trial Program With Gasco Energy

HOUSTON, Feb. 21 /PRNewswire-FirstCall/ -- Particle Drilling Technologies, Inc. (Nasdaq: PDRT) ("PDTI" or "Company") today announced that it has entered into an agreement with Gasco Production Company, a subsidiary of Gasco Energy, Inc. (Amex: GSX) ("Gasco"), to deploy PDTI's patented Particle Impact Drilling ("PID") process in Gasco's Riverbend drilling program located in Utah's Uinta Basin. The initial PID operation demonstrating the PID process in its first commercial field application is expected to begin in early to mid April of 2006.

"We believe the Gasco project is an ideal candidate for the initial commercial field application of our PID technology," stated Jim B. Terry, PDTI's President and Chief Executive Officer. "Successful field tests may lead to additional opportunities with Gasco and other operators within the Uinta Basin and throughout the Rocky Mountain region which exhibit similar drilling characteristics."

Drilling to the Uinta Basin's deeper productive objectives at depths of 13,000 feet have typically taken approximately 35 days due to low penetration rates associated with various hard rock intervals. These intervals typically occur below 9,500 feet until reaching the total depth. Testing indicates that penetration rates of three to five-times higher may be achieved using the PID system, potentially reducing the drilling time by 10 to 15 days. The Agreement is structured to compensate PDTI with 50% of the savings realized by Gasco from reduced drilling days. The term of the agreement will be on a well-by- well basis and can be terminated by either party at any time.

John D. Longwell, Gasco's Vice President of Operations, added, "We always seek modern technologies to reduce well investment that can be applied to our large inventory of drilling locations. While Particle Impact drilling technology is early stage, we believe it has the potential to significantly reduce drilling days."

Particle Drilling Technologies, Inc., headquartered in Houston, Texas, is a development stage oilfield service and technology company owning certain patents and pending patents related to the Particle Impact Drilling technology. The Company's technology is designed to enhance the rate-of- penetration function in the drilling process, particularly in hard rock drilling environments.

Certain statements in this press release that are not historical but are forward-looking are subject to known and unknown risks and uncertainties, which may cause PDTI's actual results in future periods to be materially different from any future performance that may be suggested in this press release. Such risks and uncertainties may include, but are not limited to, PDTI's ability to raise equity capital, if necessary, and its ability to obtain equity financing on acceptable terms, if at all, a severe worldwide slowdown in the energy services sector and working capital constraints. Further, PDTI is a development stage company that operates in an industry sector where securities values are highly volatile and may be influenced by economic and other factors beyond PDTI's control such as announcements by competitors and service providers.
