Fracture connectivity within fractured granitic basement geothermal reservoirs is an important factor controlling their permeability. This study aims to improve the understanding of fluid–rock interaction processes at low moderate regional strain. The Noble Hills range (Death Valley, CA, USA) was chosen as a naturally exhumed paleo reservoir. A series petrographic, petrophysical, and geochemica...

   In this paper, a new robust approach based on Least Square Support Vector Machine (LSSVM) as a proxy model is used for an automatic fractured reservoir history matching. The proxy model is made to model the history match objective function (mismatch values) based on the history data of the field. This model is then used to minimize the objective function through Particle Swarm Optimization (...

This study presents a general solution for the radial flow of tracers in naturally fractured reservoirs. Continuous and finite step injection of chemical and radioactive tracers are considered. The reservoir is treated as being composed of two regions: a mobile region where longitudinal dispersion and convection take place and a stagnant region where only diffusion and adsorption are a1 1 owed....

In order to simulate the interaction of seismic waves with cavernous/fractured reservoirs, a finite-difference technique based on locally refined time-and-space grids is used. The need to use these grids is due primarily to the differing scale of heterogeneities in the reference medium and the reservoir. Domain Decomposition methods allow for the separation of the target area into subdomains co...

Multistage hydraulic fracturing is one of the most prevalent approaches for shale reservoir development. Due to complexity constructing environments experiments, numerical simulation a vital method study flow behavior under conditions. In this paper, we propose model that considers multistage fractured horizontal well with hilly-terrain trajectory in presence natural fractures. The was construc...

Abstract. Shallow-level igneous intrusions are a common feature of many sedimentary basins, and there is increased recognition the syn-emplacement deformation structures in host rock that help to accommodate this magma addition. However, sub-seismic structure reservoir-scale implications remain poorly understood. The Trachyte Mesa intrusion small (?1.5 km2), NE–SW trending satellite Oligocene-a...

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...
