Oil and Gas
This five-day course is designed to introduce technical professionals to the fundamental aspects of reservoir engineering. Theoretical concepts coupled with numerous practical case histories are presented to assist reservoir and exploitation engineers in their primary functions - the determination of oil and gas reserves and the maximization of hydrocarbon recovery under primary, secondary, and tertiary schemes. Field development of unconventional gas reservoirs including shale gas, tight gas and coalbed methane (CBM) will also be covered. The application of horizontal wells and a number of new technologies will also be reviewed. The sessions will include a number of relevant class problems and examples.
Duration and Training Method
Five classroom days providing 4 CEU (Continuing Education Credits) or 40 PDH (Professional Development Hours)
Participants will learn to:
- Basic understanding of petroleum geology; trapping mechanism and rock types
- Review of rock and fluid characteristics and impact on reservoir performance
- The importance of the various reservoir drives and impact on reservoir performance and the expected ultimate recovery3
- Reserves definitions/classification and the industry standard techniques to estimate oil and gas reserves, including the deterministic and probabilistic methods.
- Production optimization by understanding the fundamentals of flow in porous media and the use of Nodal analysis
- The use of well test analysis tool as one of the most effective reservoir management tools to characterize the reservoirs and how to analyze various test types to optimize production and estimate reserves.
- How to minimize water production problems and control fluid coning.
- Provide good understanding of enhanced oil recovery methods with emphasis on waterflooding including how to design, monitor performance, and estimate the expected ultimate oil recovery
- Explain the difference between conventional and unconventional reservoirs, such as coalbed methane, shale gas/oil and tight sands. Illustrate the specialized techniques to evaluate the commerciality and performance of such reservoirs.
- Review the applications and performance of horizontal wells. Also illustrate the various design options of multi-stage fracing of horizontal wells and performance evaluation using both analytical and numerical techniques.
