As the oil field enters medium and high water cut stage, difficulty of measures to explore potential is increasing, geological conditions new production wells are getting worse, it more difficult select layers, effect increase gradually worse. In order improve increase, necessary refine potential, expand space well layer selection, optimize fracturing process. Therefore, we drew on successful e...

Abstract Attributed to the opacity of soil and rock mass, seepage visualization is a thorny problem in model test around diaphragm wall leakage, which has played an increasingly significant role deep excavation engineering recently. Enlightened by geoelectrical field response method, electrical potential method was proposed this study. By means experiment, applicability verified approaches for ...

We investigate erosion patterns observed in a horizontal granular bed resulting from seepage of water motivated by observation of beach rills and channel growth in larger scale land forms. Our experimental apparatus consists of a wide rectangular box filled with glass beads with a narrow opening in one of the side walls from which eroded grains can exit. Quantitative data on the shape of the pa...

the subsoil and groundwater were suspected to be polluted by leakage from underground tanks around the oil storage facility in Dhanbad, Jharkhand, India. to delineate the seepage zone, integrated geophysical methods comprising Ground Penetrating Radar (GPR) and 2D electrical Resistivity Imaging (eRI) methods were employed over the suspected zone and in the close vicinity. the studies were condu...

To determine the seepage parameters of surrounding rock during excavation of tunnels, a program of groundwater seepage (SEEP) was developed. Then finite element models are established in SEEP with the consideration of seepage equations for continuous medium, and the correctness was verified by the comparison of FLAC. Moreover, seepage back analysis program (SBAP) was developed in C++ language b...

Existing fractured gas reservoir development techniques are mainly based on dual medium numerical-simulation models, which can, to a certain extent, effectively simulate natural fractures with high fracture density; however, these models have some limitations, particularly in terms of simulating the morphology and distribution. Considering carbonate reservoirs complex fractures, this paper, we ...
