This course provides understanding of necessary geomechanics basics and its applications in the oil and gas industry. This course covers the origin of earth's stress and pore pressure in reservoir rocks, techniques and methods of assessment using well's data; it 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 deals with examples of wellbore stability, modeling and forecasting abnormally high formation pressures, deals with fracturing stimulation optimization and sanding issues; also there would be covered issues of geomechanics application to unconventional, and fractured shale oil and gas.

Nikolay Smirnov is a recognized Russian expert in geomechanics that in 2005 founded this discipline for Russian oil and gas industry. He had successfully solved numerous problems in the industry, such as drilling through “chocolate” clays, problems of horizontal wells on Achimov and Jurasic sediments, also looking at Bazhen-Abalak formation development issues, problems of developing shelf prospects with extended reach wells, problems of multistage fracturing, reservoir issues like sanding and many others. Smirnov started his career in Schlumberger Sedco-Forex in 1997 as a Drilling Engineer, working in West Africa. Throughout his carrier Smirnov was working as senior geomechanics engineer at Holditch-Reservoir Technologies in Houston Texas, which eventually became Data and Consulting services of Schlumberger Technologies. In 2005 Smirnov initiated geomechanics development in Russia as Geomechanics Domain Head for Schlumberger Russia and later expanding to Central Asia. Before coming to Russia Smirnov was developing Geomechanics technology in Beijing, China.
Nikolay Smirnov had authored and co-authored over 20 technical papers and patents. He graduated from Novosibirsk State University with degree in Geology and Geophysics. Currently he is working as a technical director of PetroGM company.
