Course & Workshop

April 21-25, 2024

Instructor: M. El Khawaga, Ph.D., P.Eng.

Who Should Attend

This course is aimed at reservoir, petroleum and exploitation engineers/technologists, and development geologists.

Course Objectives

The course provides understanding the fundamentals of the pore pressure, wellbore instability and applications in the oil and gas industry. This concepts and methods of pore pressure in different rocks, techniques and methods of assessment using well’s data. It also gives good understanding of elastic and strength (mechanical) properties of the rocks, with an introduction to the basics of experimental rock mechanics. The course also examines the main approaches of construction of Mechanical Earth Model (MEM) and the further application of these models to solve the most important issues of exploration and development of oil and gas fields. The course including examples of wellbore stability, modeling and forecasting abnormally high formation pressures. This course is designed for anyone involved in petroleum related exploration or well planning without detailed geomechanical experience.

Instructor Profile

Dr. Eng M. El Khawaga obtained his Ph.D. on Rock Mechanics in 2017. He is a senior reservoir geomechanics geologist with reservoir management and geological operations background. Mohamed’s work has centred on 3D Geomechanical modelling to support the fault seal analysis including the mechanical properties distribution through fault plane and extends to reservoir production profiles to control the fault leakage through reservoir life. In addition, he proceed sand production studies for different fields in the Gulf of Suez with supporting critical drawdown pressures along the different reservoir pressures in its whole life. As a geomechanics specialist in GUPCO, he is responsible for pore pressure prediction, detection, wellbore stability, mud weight design and selecting casing criteria in the Gulf of Suez, which considered one of the most complex rift basins structure in the world. In addition, his experience is extended to the Nile delta and western desert basins. He has the following Publications:

Project Experience:
• 3D Geomechanical modeling for fault seal analysis projects including prediction of complete lithological facies in the different wells in the project, properties distribution along the different formations and faults, distribute the mechanical properties and the stresses through the fault plane and the adjacent areas
• Pore Pressure and Geomechanical studies for more than 20 models (high pressure and highly deviated wells) in different provinces in Gulf of Suez.
• Pore Pressure and Geomechanical studies for 20 wells in East Mediterranean, Egypt.
• Sand Management studies for more than 10 fields in the Gulf of Suez which helped in sustaining the production during the reservoir life
• Maintain the production in highly week sand by applying oriented perforation techniques.
• Developing a new approach for UCS measurements of sand and shale. Two hundreds core samples measured to remodel the results and creating a strong relationship between the lab results and well logs. These results directly affected the 3D sand failure and 3D geomechanics models.
