Summary

This course introduces the concepts required to develop fluid-filled porous reservoirs in subterranean formation for a number of industrial applications. It covers the effects of fluid withdrawal and injection on in-situ rock stresses and deformation, well stimulation, deep drilling etc.

Content

-        Introduction to geo-energy & the different types of subterranean reservoirs

-        Introduction to numerical methods in geomechanics (FE/FD algorithms for hydro-mechanical coupling)

-        Deep well construction

-        Poroelasticity & flow in deformable fractures

-        Extension to thermal effects

-        Fluid flow around a well, pore-pressure diffusion, interference between wells, introduction to reservoir management.

-        Effects induced by fluid withdrawal and/or injection: fault re-activation, induced seismicity, surface deformation, cap-rock integrity, un-controlled fracturing.

-        Introduction to hydraulic fracturing for well stimulation.

-       Applications to conventional and unconventional hydrocarbon resources, deep geothermal systems and CO2 geological storage.

Keywords

good knowledge of continuum mechanics

Learning Outcomes

By the end of the course, the student must be able to:

Transversal skills

Expected student activities

A group project will be assigned mid-october and run through the end of the semester. It will count for 50% of the grade. It will involve the following steps: i) solving anaytically/numerically a simplified configuration linked to a  real engineering problem, ii) discussing order of magnitude via dimensional analysis, iii) and discuss the relevance of the results for practice.
