HOUSTON, Oct. 17 /PRNewswire-FirstCall/ -- The Board of Directors of Particle Drilling Technologies, Inc. (Nasdaq: PDRT - News; "Particle" or "Company") today announced that its Chief Financial Officer, J. Chris Boswell, will assume the additional responsibilities of interim President and Chief Executive Officer on November 15, 2005, when the current interim President and CEO, John D. Schiller, Jr., steps down. Schiller will now devote full time to the leadership of Energy XXI (AIM: EGY), an oil and gas asset acquisition company that will begin trading on London's Alternative Investment Market (AIM) Exchange on October 20, 2005. Particle's board has engaged Preng & Associates, a leading talent search firm that specializes in the energy industry, to identify a qualified candidate to assume the full-time President and CEO position for Particle with a target completion date of March 1, 2006.

"We would like to thank John for leading the efforts toward bringing our technology to this stage," stated Particle's Chairman Ken LeSuer. "Although he will be stepping away from the Company's day-to-day operations, he will remain on our Board of Directors and continue to add significant value going forward. We wish him and Energy XXI the greatest success as they look to build an exciting oil and gas company."

Schiller added, "I believe that we have accomplished a great deal during the past eleven months and I believe the Company is in very capable hands. I am confident that with Chris in charge until we identify the right full-time candidate, we will not miss a beat as we continue to move toward our goal of bringing the Particle Impact Drilling ("PID") technology to market."

Boswell, age 44, has over 20 years experience in financial management focused in the energy industry and began his career at Arthur Andersen & Co. Later he served in management positions with Price Waterhouse, LLP in Houston, Texas. Boswell was a founding partner in Particle and has served as a Director and as CFO of the company since August 2003. Prior to that, he served as Senior Vice President and Chief Financial Officer of Petroleum Geo- Services. During Boswell's tenure at PGS, it grew from a small enterprise in 1994 to a large integrated oil service company with over $1 billion in revenue. While at PGS, Boswell and other senior executives at PGS developed the concept to create a unique oil and gas company using PGS' seismic data library as seed capital. This company became Spinnaker Exploration Company and was recently sold for $2.5 billion. Boswell is a 1984 graduate of the University of Texas at Austin.

Additionally, Particle has mobilized its PID system to the GTI Catoosa facility to begin the next round of development testing. The Company is currently on location and expects to drill several hard rock intervals during the next two weeks. Once Particle has logged sufficient hours on the PID system and evaluated the results of this drilling program, a press release will be issued to discuss the results.

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.
