Nowadays, unconventional resources of gas have been brought into the forefront of the energy future due to the increase in demand of hydrocarbon and decline of production from conventional reservoirs. These energy sources are a fast-growing market and are recognized as having huge future potential for production worldwide.
Due to low permeability of unconventional resources, production at commercial level requires conducting effective hydraulic fracturing and applying horizontal drilling technologies. Therefore, successful production from such complex reservoirs, with a typical poorly-defined gas-water contact, natural fractures, and very low matrix permeability, is heavily dependent on the stress regime requiring sufficient geomechanical analyses.
Geomechanics is an essential component of stimulation of and production from both conventional and unconventional reservoirs. It is because rock deformation and stress caused by drilling and production is very likely to affect permeability and porosity during the whole life of a reservoir. The extraction of hydrocarbons from a reservoir or the injection of fluids changes the in-situ stresses, which potentially leads to compaction and subsidence impacting well and completion integrity, cap-rock and fault-seal integrity, and fractures behavior. However, geomechanics for unconventional resources is to some extent different from conventional reservoirs due to intricacy imposed by inelastic matrix behavior, stress sensitivity, existence of cleats and natural fractures, rock rheology, and different pressure-temperature environments. In addition to the complex geology, petrophysics, and reservoir heterogeneities, unconventional reservoirs provide unique challenges related to hydrocarbon storage and flow in complex rock systems, thus requiring an improved fundamental understanding for effective production.
This presentation discusses the geomechanical aspects of unconventional resources and how it adds value to the development of this type of reservoirs.
