Particle Drilling Technologies Completes Successful GTI-Catoosa Testing Program and Announces Fourth Quarter and Year End Results

• Particle Impact Drilling (“PID”) penetration rates meet expectations
• Shot injection system performs reliably
• PID system ready for commercial field trials

Houston – November 9, 2005 – Particle Drilling Technologies, Inc. (NASDAQ: PDRT) today announced that it has completed its testing program at the GTI Catoosa (Catoosa) drilling facility and also announced its financial results for the fourth fiscal quarter and the year ended September 30, 2005. At Catoosa, the Company was able to successfully run the patented Particle Impact Drilling (PID) system while drilling multiple hard and abrasive intervals. Additionally, the Company was able to evaluate performance and further develop operating procedures for the PID system.

As a result of the tests at Catoosa, the Company accumulated meaningful hours on the PID system and increased its operating knowledge of how it performs under several different operating conditions. The Company also successfully developed and tested procedures for items that did not perform satisfactorily in its prior tests at Catoosa in July of this year, including enhancing the shot injection system, reducing the connection time and developing improvements in the handling of shot in the wellbore and at the surface. The shot injection system was improved and functioned and performed reliably during the test.

The various operating conditions tested include two drill bit (PID bit) designs; two PID bit sizes; both low and high flow rates of drilling fluid ranging from 425 to over 600 gallons per minute, and different shot injection rates. All conditions tested were effective at delivering target level rates of penetration through very hard and abrasive intervals. During testing the Company identified certain engineering and design improvements that will be implemented to make the system more robust. In some instances, the high flow PID bits suffered erosion problems associated with the nozzles. The Company is confident that with minor changes this issue will be overcome, as it was not a prevalent problem with all PID bits tested. More importantly the Company believes that with the existing PID bit it will be able to drill 300 feet a day in its target market thus achieving its stated goal for success. The modifications needed to improve performance can be fully evaluated in the Company’s research facility in Houston, Texas avoiding the need to return to Catoosa or TerraTek.

During the test program, representatives from potential customers visited the test site and witnessed testing. The Company received positive feedback and now believes the system is ready for commercial trials in target application areas. The immediate market for this drilling system will focus on wells that are drilling less than 100 feet per day in a normal pressure environment utilizing a 7 7/8” or 8 ½” bit. Based on current customer inquiries, management estimates the PID system will be deployed in a revenue generating mode by the first calendar quarter of 2006.

In its continuing effort to enhance the PID technology, the Company has retained Beeken TechQuest, Ltd (Beeken) to develop a more efficient and cost effective shot injector system. Beeken is led by Dr. B.N. Murali, formerly the Vice President of Technology for Halliburton Energy Services. During his last 9 years at Halliburton, Dr. Murali was in charge of developing new technology for all product service lines. Beeken is designing a system to replace the existing shot injection system with a simpler, less expensive approach. Once successfully designed and tested, this system has the potential to reduce the cost of the PID system while providing redundant injection capability.

The financial results reflect the Company’s continuing status as a development stage company generating no revenue as well as ongoing planned investment in the Particle Impact Drilling (PID) system. The following is a summary of the quarterly and full year results:

The Company’s interim President and Chief Executive Officer, John Schiller, commented, “The team at Particle Drilling continues to build upon its previous achievements as reflected in the significant progress we made during our recent test at Catoosa. We are confident that our drilling system is robust enough for specific commercial field work. As previously announced, I will be shifting my focus to Energy XXI Acquisition Corporation (AIM:EGY), which recently raised $300 million, through an IPO on the London Stock Exchange AIM market, to acquire oil and gas properties. On November 15, 2005, I will be stepping down from the day-to-day operations of the Company and Chris Boswell will step in as interim CEO until the Board has the opportunity to identify a full time CEO. Due to my confidence in Chris and the rest of the Particle Drilling team, I will remain as an active Board member.”

Chris Boswell, the Company’s current CFO who will assume the interim CEO role on November 15, 2005, commented “We wish John continued success in his new endeavors, but know that we can rely on him for leadership and guidance as we move toward commercialization. In fact, we have already tapped into his network in the industry to assist with operational matters and to further existing conversations with potential customers. We are excited about the market potential of this product, and while we are still in the early stage of development, I believe acceptance of our PID technology will expand rapidly as we commercialize our technology and further demonstrate its compelling value proposition.”
