Petroleum engineering has been the discipline of vital importance in meeting the global demand for energy. Geomechanics has evolved to become a critical area in petroleum engineering. Although drilling a well, whether vertical, deviated or horizontal, is the main vehicle to produce oil and gas from deep reservoirs, it also serves reaching for coal, geothermal energy, and gas hydrates. Additionally, drilling a well is needed for waste disposal and CO2 sequestration.
Drilling a well is basically creating a circular hole and introducing drilling and completion fluids that disturb the in situ stress field of an otherwise stable reservoir. This introduces a series of phenomena related to near wellbore on a wellbore scale and later, upon production, on a reservoir scale. The circular hole causes a new stress concentration that extends in the reservoir. This stress concentration, which differs from the far-field original stress field, could exceed formation strength, resulting in failure. The circular hole also creates a free surface that removes natural confinement which can, depending on the mechanical properties of the formation, reduce formation strength and trigger elastic, plastic, and time-dependent deformations. Similarly, introducing foreign fluids to the formation disturbs pore pressure, creating poroelastic and poroplastic deformations due to modified effective stress field within the porous media. Depending on fluid interaction with the rock matrix, the formation cohesive strength and internal friction angle are reduced.
This Special Issue will focus on all geomechanics problems related to drilling a well into reservoirs at depths for all the objectives mentioned above and the processes occurring in the reservoir following well penetration. Therefore, technical papers are invited in all geomechanics-related areas such as wellbore stability, cementing, perforation, hydraulic fracturing, production, reservoir compaction, subsidence, sand production, geothermal reservoir engineering, gas hydrate production, waste disposal, and CO2 sequestration. Papers of multidisciplinary nature that present innovative solutions are highly encouraged. These geomechanics applications can be related to conventional and unconventional reservoirs.
