Barite scalings are a common cause of permanent formation damage to deep geothermal reservoirs. Well injectivity can be impaired because the ooling saline fluids reduces solubility barite, and continuous re-injection supersaturated forces barite precipitate in host rock. Stimulated reservoirs Upper Rhine Graben often have multiple relevant flow paths porous matrix fracture zones, sometimes span...

In this paper, decline curve analysis is used for estimating different parameters of bounded naturally fractured reservoirs. This analysis technique is based on rate transient technique, and it is shown that if production rate is plotted against time on a semi-log graph, straight lines are obtained that can be used to determine important parameters of the closed fractured reservoirs. The equati...

hydraulic fracturing in the fractured reservoirs plays a significant impact on the production rate. in this study, the hydrostatic condition is taken into account, the hydraulic fracturing operation was applied in every direction usinga written distinct element code. in each direction the hydraulic fracture is applied with different lengths and in each level the amount of production is predicte...

we use a multi-resolution analysis based on a wavelet transform to upscale a 3d fractured reservoir. this paper describes a 3d, single-phase, and black-oil geological model (gm) that is used to simulate naturally-fractured reservoirs. the absolute permeability and porosity of gm is upscaled by all the possible combinations of haar, bior1.3, and db4 wavelets in three levels of coarsening. the ap...

stimulated wells completed in commingled reservoirs, i.e., This paper examines tic transient pressure response from slug reservoirs in which the layers communicate only at the wellbore tests in wells completed in multiple, hy&aulically fractured coal and not in the fractures or reservoir. Under these conditions, our seams. We developed a model for stimulated wells producing model is applicablee...
