The aim of the course is to introduce basic concepts in geomechanics and demonstrate its application in fractured reservoir evaluation and borehole stability. These calculation of horizontal maximum minimum stress, use of borehole images and acoustic logs in geomechanics and the fluid flow potential of critically stressed fractures.
The course will be conducted in a class with a pc or laptop for each student with Excel. A working knowledge of Excel and Powerpoint is required.
Stress conditions of fracturing. Shear and tensile fractures
Elastic, plastic and viscous materials, rock strength, rigidity
Fracture prone weak brittle rocks such as chalk and limestone
Drilling induced fractures and breakouts on image logs
Estimation of minimum and maximum horizontal stress
Slippage, dilatation and leakage tendency of fractures
Sait Ismail Ozkaya is a structural geologist with a Ph. D. degree from the University of Missouri USA. He also has an M.Sc, degree in Computer Science and strong background mathematics and computer programming. He was a professor at Kuwait University before he joined Baker Atlas in 1996. He has been working an independent consultant since 2003. His specialty is fractured reservoir characterization. He has worked on a vast number of fractured carbonate and clastic reservoirs in the Middle East. His work covers full spectrum from borehole image interpretation to fracture data generation for single or dual porosity reservoir simulation. He has been particularly successful in evaluating fracture flow patterns by integrating petroleum engineering data with geological fault/fracture information. He has used a wide range of software and techniques such as 2D and 3D Discrete fracture network modeling and prediction with Neural Networks. He has written several software packages for fracture analysis and has many publications in structural geology, computer applications and fracture analysis.
