These analyses are the reservoir compaction, displacement of ground surface, integrity of the caprock and the stability of the natural fractures and faults during the depletion and injection phases of the UGS operation. The targeted storage rocks are stiff with Young's modulus more than 50GPa...

... proposes a fracturing based huff and puff technology. Fracturing huff and puff technology is mainly divided into three stages. The first stage is energy storage, in which low displacement water is injected to supplement formation energy, the second stage is oil washing, in which high displacement water...

... model that incorporate imbibition displacement, as proposed by ( Delshad et al., 2003 )). Imbibition in the matrix arises from capillary pressure variations between channels of different sizes, influenced by gravity and interfacial tension. This study presents the oil-water relative permeability...

... to assess the field-scale geomechanical related risks associated to production. The changes in stresses, strains and displacement induced by the carbonate reservoir depletion are obtained over the entire model at the end of each geomechanical simulation step. These are used to conduct detailed geomechanical...

..., and the oil distribution evolution during gas displacement, could contribute to the development of shale oil. In this study, the one- and two-dimensional NMR spectra were used for the above studies. Two Gulong shale dry cores with different fracture bedding characteristics were tested in the experiments. NMR...

... trapped within the pore space. However, trapping of the intermediate wetting phase (i.e., water in a mixed-wet system during three-phase flow) is also possible and can be quite substantial under certain circumstances. In this work, we have carried out three displacement experiments on mixed-wet Berea...

... Abstract The micro-nano displacement system is a novel flooding system developed in recent years, and has garnered considerable attention of scientists. It can achieve deep fluid diversion and expand the swept volume. Owing to its low cost, we employed the flake nanomaterial laponite...

... Abstract During the primary well cementing operation, when the cement slurry is pumped into the annulus around the outside of the casing string, it is very critical not to over displace and let the displacement fluid enter the annulus. Traditionally, to determine when to stop the cement...

The magnitude and duration of the jet-induced "pressure pulse" in the annular space between the formation wall and the casing are a key to efficient displacement during the wash and cementing processes. Displacement efficiency, in terms of the percentage of mud or cement...
