Course Description

A reservoir’s life begins with exploration that leads to discovery, which is followed by delineation of the reservoir, development of the field, production by primary, secondary, and tertiary means, and finally to abandonment. Integrated, sound reservoir management is the key to a successful operation throughout a reservoir’s life. Further, the need to enhance recovery from the vast amount of remaining oil and gas-in-place, plus the global competition, requires better reservoir management practices. Reservoir management is the application of scientific principles to solve issues arising during the development and production of oil and gas reservoirs.

This course is designed to provide many tools and techniques to help address the challenges of providing a more reliable and sound reservoir engineering & management. Participants can learn a wealth of classic information on the concepts and processes involved in reservoir engineering and management. The course presents insights about data acquisition, reservoir performance analysis & forecast, field development planning, reservoir management economics and improved recovery processes.

Objectives

• Use appropriate approaches in reservoir engineering and management.
• Be familiar with the appropriate data collection, analysis, validation and integration process.
• Illustrate the points of integration between the different disciplines (geoscience, engineering etc.) during the applications of the reservoir management concepts

Applications.

• Ensure the appropriate execution of the reservoir management process.
• Use the Interdisciplinary Synergistic approach to efficient reservoir management.
• Include each reservoir management component and the importance of timing and cost/benefit analysis.
• Apply the different methods of reservoir performance analysis and forecast & give emphasis on the integration of production/injection data, pressure data and any subsurface data.
• Acquire an up to date knowledge on the improved recovery processes related to water flooding, thermal methods, chemical methods and EOR screening guidelines.

Training Method

A highly interactive combination of lecture and discussion sessions will be managed to maximize the amount and quality of information, knowledge, and experience transfer. The sessions will start by raising the most relevant questions and motivating everybody to find the right answers. The attendants will also be encouraged to raise more of their questions and to share developing the right answers using their analysis and experience. Course material through power point equipped with necessary animation, learning videos, and general discussion to provide the participant with full understanding concerning the subject course will be provided.
