Abstract Mechanical properties of petroleum reservoirs can be determined via static techniques based on laboratory triaxial tests under reservoir conditions. Dynamic approaches represent an alternative in cases where such data are unavailable. elastic calculated using ultrasonic wave measurements the or situ well logging. Different relationships have been proposed to estimate from dynamic ones ...

Geomechanical stability issues may arise due to induced thermal stresses because CO2 will generally reach the storage formation at a temperature lower than that of the reservoir. Cold injection will form a cold region around the injection well, which will induce thermal stress reduction. We simulate cold CO2 injection in deep saline formations in a normal faulting stress regime and investigate ...

Permeability an important property plays a key role in reservoir performance, numerical simulation, drilling and production planning. In such reservoirs, stress strain alters induced by extraction injection of fluid may substantially change permeability irreversible manner. With regard to this phenomenon, several reservoirs require consider straindependent permeability, order have accurate perf...

Geological structures are by nature inaccessible to direct observation. This can cause difficulties in applications where a spatially explicit representation of such structures is required, in particular when modelling fluid migration in geological formations. An increasing trend in recent years has been to use analogs to palliate this lack of knowledge, i.e., exploiting the spatial information...

Abstract Several benefits of CO 2 injection are reported in the literature such as its ability to mitigate greenhouse gas emissions and increase oil recovery at a low cost. However, correlated reservoir-engineering problems with low-temperature including formation damage leakage risk still uncertain has not been comprehensively investigated. This research examines effect on lowering breakdown p...
