... show that fast injection prevents significant compaction in the reservoir. Besides, the calculated shear deformation in the overburden is utilised to study wellbore stability during storage. The results indicate that the accurate characterisation of the porosity distribution in the reservoir as well...

... be amplified by the gravitational loading of the weak underlying shale. We use two-dimensional plane-strain, finite element code to investigate the mechanics of growth of a shale-cored fold in the South Caspian Sea Basin, where c.10 km of sediment was deposited in the last 6 Myr. The overburden and syn...

... ABSTRACT The isotropic homogenous assumption in the conventional Geertsma model is often contradicted by reality because the rock properties in the overburden are typically anisotropic and often can be quite different from the reservoir. Thus, we present an analytical solution that extends...

.... The present study evaluates a single tunnel with an overburden of 1000 m and an in-situ stress ratio ranging from 0.25 to 3 to prepare a training and validation set. The results show that with an acceptable 0.1% error, the Levenberg-Marquardt Back-Propagation Method (LMBP) of Artificial Neural Network (ANN...

.... The objective of this work is to present the tests results, how they were performed and the operational problems faced, always seeking the shortest rig time. These results favored the understanding of the reservoir and cap rock behavior. structural geology aperture overburden pressure Upstream Oil...

For planning of hydraulic fracture stimulation treatments and for the safe operation of injection wells in fracture modus, the Holy Grail is thus to obtain a continuous stress profile through the overburden and the reservoir. Equinor has put...

... ABSTRACT: Multi-scale numerical geomechanical models for reservoir and overburden deformation in the Tyra chalk field (Denmark) were made, and calibrated by laboratory deformation tests and field data. The mechanical interaction between the compacting and deforming formation, cement...

... ABSTRACT: A multi-scenario geomechanical modeling approach is presented to investigate the potential mechanisms that lead to a series of observed well deformation incidents in the deep overburden overlying a depleting and compacting chalk reservoir in the North Sea. Complementary...

... ABSTRACT: Fluid production from or injection into a subsurface reservoir leads to stress pressure changes inside and outside the reservoir. The overburden often consists of low permeability shale, and the undrained pore pressure response may be estimated from Skempton’s empirical equations...
