I am a Licensed Professional Engineer in Texas, <br />Wyoming and California, a member and past officer of the Society of Petroleum <br />Engineers, a member of the Society of Petrophysicists and Well Log Analysts and a <br />member of the Society of Petroleum Evaluation Engineers. A resume of my education <br />and professional petroleum engineering experience is attached hereto as Attachment 1. <br />As part of my practice I routinely review, interpret and advise clients regarding cement <br />bond logs and other cement evaluation logs. During my employment with Schlumberger, <br />from 1987 to 1992, I personally ran hundreds of bond logs and cement evaluation logs, <br />(the predecessor to today's ultra -sonic tools). <br />
