The seismoelectric logging method is based on measuring the electric field generated by seismic waves in a fluid-filled borehole. Two kinds of electromagnetic (EM) fields can be generated within the formation and at the interface of formations. One is a stationary or local EM wave and the other is a radiating EM wave. In this paper, we make various fractured borehole models with artificial mate...

The heat transfer characteristics of a downhole heat exchanger (DHE) were studied experimentally in a laboratory scale. The permeable aquifer was simulated by using a rectangular tank filled with glass beads of diameter ranging from 3 to 5 mm. The downhole heat exchanger was modeled by a Ushaped copper tube. We have simulated various configurations of DHE by changing the geometrical parameters ...

In hydrocarbon drilling, mud filtrate penetrates permeable formations and alters the pore fluid characteristics in immediate vicinity of borehole. Typically, prevailing situ fluids are displaced by invading filtrate, which leads to gradually changing distributions electrical properties. Understanding this invasion process is crucial for interpretation logging data associated reservoir evaluatio...

Absence of a permeability log necessary to assess reservoir quality and injectivity for potential CO2 storage in the heterogeneous complex South Georgia Rift (SGR) basin provides motivation this study. The focus study was on Triassic-Jurassic red beds buried, entrenched beneath Cretaceous-Cenozoic Coastal Plain sediments. Moreover, significant cost typically between $10 M $100 associated with d...

Extensive work has been done in the recent years involving use of conventional and passive seismic data for fracture characterization. This is particularly the case with unconventional reservoirs such as shale gas, shale oil and geothermal fields. The purpose of our study is to combine the benefits of conventional seismic data that provides relatively higher resolution reservoir characteristics...

Fluid flow in a dual permeable medium (DPM) is essential solute transport mining and aquifer studies. In this paper, water flushing into contaminated DPM containing fine-grained lenses with different geometries was investigated the Lattice Boltzmann Method (LBM). The LBM model used study D2Q9 relaxation time of 1, cohesion value 3 for fluid density 1 (mu.Lu-3). saturated contaminant that usuall...

Fracture characteristics—such as orientation, type, fluid storage capability, and permeability—are complex yet essential information for understanding fractured reservoirs. Fractures are often perceived as permeable pathways, although many fractures partially or completely inhibit permeability within a reservoir. For example, opening-mode fractures (joints) may be partially or entirely sealed h...

The occurrence of permafrost in a highly permeable catchment has a profound effect on runoff generation. The presence of permafrost effectively makes the subsoil impermeable. Therefore, overland flow can be the dominant runoff-generating process during periglacial conditions. The absence of permafrost will promote subsurface drainage and, therefore, saturation excess overland flow can become th...

The permeability structure of the Sumikawa geothermal field in northern Japan has been the subject of an extensive pressure-transient testing investigation since 1986. In this paper, various pertinent data sets are presented and analyzed, including results showing reservoir heterogeneity (i.e. boundary) effects and apparent double porosity behavior. Interference tests between wells SB-3 and SD-...
