Summary
Please note this course is offered in partnership with Rose and Associates. They will deliver and provide all logistics for the course.
Business Impact: This course will enable participants to critically assess opportunities, compare them to successful analogs, and invest in those projects whose characteristics are consistent with commercial success.
This class provides an introduction to the exploration, appraisal, and development of oil and gas resource plays. It identifies the data that need to be collected, how to analyze and interpret them, and how to integrate and apply this knowledge to the decision-making process. Case studies from a large number of active plays are presented.
Duration and Training Method
A virtual classroom course divided into 8 four-hour webinar sessions over four days, featuring lectures, discussions, exercises, and case study poster sessions.
Participants will learn to:
- Compare and contrast the rock and fluid characteristics of oil and gas resource play systems, including shales, sandstones, carbonates, and coals.
- Understand what geoscience and engineering data need to be collected, including cores, logs, well tests, and production data.
- Analyze and integrate the acquired data to make good decisions about what the next steps should be, including if and where to drill additional wells.
- Determine the inconsistencies, omissions, and errors associated with analyzing and interpreting acquired data, and take steps to mitigate these problems.
- Compare and contrast the different drilling and completion techniques used in these reservoirs and learn the key factors that control their selection.
- Understand the production characteristics and forecasting tools that can be used for determining rates and ultimate recoveries from these wells.
- Determine the key questions to ask and critical uncertainties to be addressed, and how to resolve these through the integration of various data and disciplines.
- Apply successful industry practices in formulating exploration, appraisal, piloting, and development project strategies.
- Understand the non-technical factors affecting this work, including environmental, leasing, marketing, political, and financial considerations.

Who should attend
This course is intended for geoscientists, petrophysicists, engineers, and managers who are seeking a comprehensive introduction to oil and gas resource plays. It is appropriate for those with no previous experience in these reservoirs, those that have some experience and want to broaden their understanding, and more experienced people who want exposure to some of the most recent technologies and practices. It is not intended as an advanced course for individuals with extensive experience working these reservoirs.
Prerequisites and linking courses
There are no prerequisites for this course.
Additional insight into resource plays at a Basic Application level is presented in N184 (Unconventional Resources: The Main Oil Systems), N259 (From Outcrop to Subsurface: Understanding and Evaluating Shale Resource Plays), and N274 (Unconventional Resource Engineering for Geoscientists).
