J. MATTHEW CONRAD, P.G., is Senior Vice President, Oil & Gas Division, Marshall Miller & Associates, Inc., in Kingsport, Tennessee. He received his B.S. and M.S. in Geology (1984 and 1987) from West Virginia University. Mr. Conrad is a petroleum geologist with over 22 years of diverse exploration and development experience in conventional, shale gas and coaled methane (CBM) reservoirs. He has worked in a variety of geologic settings including CBM resource assessment and evaluation in most of the U.S. coal basins, Western Canada, and China. Mr. Conrad has gained significant practical work experience in CBM production and drilling in the central Appalachian Basin. As the project geologist for Equitable Production Company, he was involved in the initiation and development of the Nora CBM Field, Virginia, including the drilling of over 400 CBM wells. Mr. Conrad also has a wide range of work experience mapping conventional oil and gas reservoirs throughout the U.S. in several different basins. He currently oversees the Oil & Gas Division at MM&A. His primary responsibilities include supervising regional CBM evaluations, evaluating conventional oil & gas and shale gas properties, assisting in reserve evaluations, providing due diligence support for company acquisitions and developing new business opportunities. Over the last few years, Mr. Conrad has participated in over 30 Marcellus Shale geologic and reserve evaluations. He has over 25 technical publications and has given several presentations regarding Marcellus Shale development to various organizations. Mr. Conrad is a registered geologist in four states and is a member of the American Association of Petroleum Geologists and the Society of Petroleum Engineers.

Horizontal Drilling Technologies
❖ Recent advancements in drilling and completion practices have helped unlock potential of gas shale plays
❖ Exposes more of the organic shale horizons
❖ Allows more natural fractures to be intersected in wellbore
❖ Enhances initial production rates and ultimate gas recoveries
❖ Requires fewer wells to drain natural gas reserves
