Evaluating Shale and Tight Oil & Gas Reservoirs

This 3 to 5 day course provides an extensive introduction to the exploration, appraisal, and development of unconventional reservoirs. It identifies the data that needs to be collected, how to analyze and interpret it, and how to integrate and apply this knowledge to the decision-making process. Participants will develop a broad understanding of the practices and pitfalls in assessing these reservoirs and will reinforce this knowledge by analyzing case study posters as teams.
