The Turaszówka crude oil field is situated within the borders of Krosno town. The oil resources are nearly depleted. Many of the boreholes have already been liquidated. Currently, only 22 boreholes are being exploited. Eight of them are watered and exploiting oil along with the reservoir water. The boreholes were submitted for producing the geothermal energy, because of their location. They are...

A pilot carbon dioxide (CO2) sequestration experiment was carried out in the Michigan Basin in which 10,000 tonnes of supercritical CO2was injected into the Bass Island Dolomite (BILD) at 1050 mdepth. A passive seismic monitoring (PSM) network was operated before, during and after the 17-day injection period. The seismic monitoring network consisted of two arrays of eight, three-component senso...

The oil in hydropower station catchment wells is a source of water pollution which can cause the downstream river to become polluted. Timely detection effectively prevent expansion leakage and has important significance for protecting sources. However, poor environment insufficient light on surface make difficult, real-time performance poor. To address these problems, this paper proposes well m...

XX oilfield has a total of 10,561 oil and water wells, 6,790 wells were drilled in the oil-water layer, but only 10.3% so development degree same layer is relatively low. In stage cut stable production, geological reserves are considerable. Based on large number data statistics this paper understands developed situation characteristics plane vertical distribution, discusses feasibility to add p...

Abstract Stimulation of unconventional tight oil formations via horizontal wells has seen increasing cases fracturing infill in recent years. The effectiveness such a strategy is mainly dependent on the proper characterization stress evolution and an accurate forecast subsequent fracture propagation region neighboring after considering production performance injection schemes parent wells. In t...

This paper presents new production decline curves for analyzing well production data from radial and vertically fractured oil and gas wells. These curves have been developed by combining decline-curve and type-curve analysis concepts to result in a practical tool which we feel can more easily estimate the gas ~or oil! in place as well as to estimate reservoir permeability, skin effect, fracture...

Water flooding is widely used for oil recovery. However, how the introduction of bacteria via water flooding affects the subsurface ecosystem remains unknown. In the present study, the distinct bacterial communities of an injection well and six adjacent production wells were revealed using denaturing gradient gel electrophoresis (DGGE) and pyrosequencing. All sequences of the variable region 3 ...

In recent years, big data and artificial intelligence technology have developed rapidly are now widely used in fields of geophysics, well logging, test analysis the exploration development oil gas. The shale gas requires a large number production wells, so inherent advantages for evaluating productivity wells analyzing influencing factors whole block. To this end, paper combines BP neural netwo...

In this study, a hybrid intelligent model has been designed to predict groundwater inflow to a mine pit during its advance. Novel hybrid method coupling artificial neural network (ANN) with genetic algorithm (GA) called ANN-GA, was utilised. Ratios of pit depth to aquifer thickness, pit bottom radius to its top radius, inverse of pit advance time and the hydraulic head (HH) in the observation w...

in this paper, a novel hybrid model based on neural network and game theory is proposed to support the analyzers in oil market. in this model, first the neural network is utilized to learn the oil prices associated with opec production level and usa imports level. then the learned neural network is applied by a game model. finally the nash equilibrium points of the game present the optimum deci...
