Material properties is one of the most significant variables in terms efficiency. The sediment layer a coal pit mine has possibility sticking to equipment bucket and reducing its productivity, especially disposal area. Consequently, stickiness close definition adhesivity level; thus it may be associated with geomechanical properties. Various soil classification area was investigated identify re...

Conventional petroleum reservoir simulators use constant rock compressibility to denote deformation. However, due the stress-sensitive nature of shale formations, using in does not accurately capture pressure diffusion reservoir, leading a higher error margin flow rate estimation. Fluid coupling with geomechanics is used account for such phenomenon numerically. Such an approach important numeri...

Evaluating top seal integrity is crucial for successful subsurface CO2 storage. Caprock shale geomechanical properties are complex and influenced by various parameters processes. It challenging to understand the role of factors affecting properties; therefore, an integrated approach required evaluate shales. In this study, we investigated caprock Early Jurassic shaly Drake Formation overlying r...

The oil and gas industry has been an integral fundamental sector of the Russian economy for past few years. main problems this have traditionally deteriorating structure reserves; depreciation assets; slowdown decline in production. Recently these complicated by a number new negative trends related to underinvestment, limited financial resources, access equipment technologies. task research is ...

the cold climate is a favorable parameter for the development of tension cracks and decrease of rock brittleness. therefore, this paper attempts to investigate the hamekasi porous limestone in order to predict the brittleness indices during freeze-thaw cycles. the freeze–thaw test was executed for one cycle including 16 h of freezing, and 8 h of thawing. the geo mechanical properties and brittl...

This paper investigates the consequences of time-dependent deformation on stress changes and resulting geomechanical risks from injection CO2 into geologic reservoirs. Using 3D fully coupled fluid flow-geomechanics simulations, it is shown that when occurs in caprock, shear decreases caprock but increases reservoir. The magnitude this transfer to reservoir affected by characteristic time scale ...
