APIS – Assessment of production induced stresses

PhD thesis C. Haug

Numerical modelling of production-induced stress changes

Dea Logo

The withdrawal of fluids from reservoir rocks at depth is accompanied by a decrease in pore fluid pressure in the reservoir. These changes in pore pressure result in compaction of the reservoir and in changes of the effective stress state within the deposit and its surroundings which can possibly lead to induced seismicity.

In the framework of a bilateral research project with DEA (Deutsche Erdoel AG) numerical geomechanical modelling studies are being conducted to systematically investigate the stress changes at depth associated with production of natural gas. These studies aim at identifying those influencing factors that can have relevant impact on the reactivation of faults. Special focus is on reservoirs that are sub-structured in individual compartments. By means of parameter studies the role of geometrical factors, hydraulic and mechanical rock properties, state variables, fault properties and production parameters is examined.
