This 5-day course is designed for technical professionals involved in evaluating or developing unconventional gas reservoirs. For many years the oil & gas industry knew unconventional reservoirs held a tremendous volume of natural gas but only recently has the industry developed the techniques to properly evaluate and develop this resource. The reason for this delay was that most gas development technology, and most course material taught in Universities, was developed over many decades for conventional reservoirs and these methods simply are not adequate for unconventional reservoirs.

Following the advances in technology and reservoir characterization for unconventional reservoirs, the development of this resource has taken center stage in North America and Australia. For example, the United States is now the largest producer and consumer of natural gas and since 2010 most of their gas is being produced from unconventional reservoirs. The industry is now aware most of the unconventional gas resource in the world is outside North America so, in just the past few years, a tremendous amount of attention has swung to the numerous untapped unconventional gas prospects in dozens of countries. Many in the industry now understand that unconventional reservoirs will continue to grow in importance and the success of companies and individuals will depend on how quickly they can learn and adapt to the unique terms and concepts involved in evaluating and developing unconventional reservoirs.

The first three days of the course will focus primarily on gas development from Coal (CBM, CSG, CSM) and the final two days will focus on developing Shale Gas. In addition, the evaluation methods for Shale Gas combine methods from Coal and Tight reservoir development and so attendees will also gain a good understanding of various different ongoing plays.

Class exercises will be completed each day and so attendees will need to bring a calculator to solve simple equations. Case studies and class examples will present the steps to determining; resource volumes, maximum allowable investments, recovery factors, specific well locations, and selecting completion methods. Data for the example problems will come from actual development projects, primarily those where the instructor has been involved, to help illustrate the quality and types of data commonly available for evaluation.
