Reservoir Engineering for Petroleum Production Engineers
This seminar represents the core of reservoir engineering and the foundation for all future studies in this subject. A 5-day, in-depth study of the subject is presented. Numerous engineering practices are covered ranging from fluid and rock properties to simulation and field development planning. Reservoir engineering is also presented in the context of a modern, multi-disciplinary team effort using up to date technology.
An extensive manual and set of references is included. This seminar has been taught for many years on a worldwide basis. It has been continuously updated and improved by a well qualified and experienced consultants.
Participants will gain the experience in learning reservoir engineering calculations through the use of many practical examples. This course is intended to provide an understanding of the fundamental principles of petroleum reservoir engineering. Course participants will examine: Critical properties of reservoir rocks Fluid (oil, water, and gas) PVT relationships Methods to calculate hydrocarbons initially in place Dynamic techniques to assess reservoir performance Parameters that impact well/reservoir performance over time Well testing principles and techniques Aquifer characterization Reservoir drive mechanisms for both Oil and Gas reservoirs Reservoir simulation techniques Oil and gas field development planning principles Forecasting production decline Enhanced oil recovery processes.
The seminar is intended for petroleum engineers, geologists and others interested in the behaviour and performance of Oil & gas reservoirs, Exploration specialists, geologist, drilling engineers who want to learn the basics of reservoir engineering and the procedures required to properly manage a reservoir's development.
