Abstract Hydrocarbon gas flooding/Huff-n-Puff (HNP) can improve the oil recovery in unconventional reservoirs. Here, mechanisms accounting for fluid flow low-permeability and ultra-low permeability reservoirs were experimentally theoretically investigated. Core plugs collected from a typical China oilfield utilized experiments. Additionally, methane was used as injection agent to conduct natural HNP/displacement The results indicated that use of an energy supplement HNP development method...
Abstract This article focuses on the study of identifying quality tight sandstone reservoirs based machine learning. The learning method – Gradient Boosting Decision Tree (GBDT) algorithm is used to design and classify reservoir quality. First, it logging data, core observation, cast thin section, physical statistics. permeability, porosity, resistivity, mud content, sand-to-ground ratio, sand thickness were preferred as evaluation criteria in area, gray correlation was obtain categories...
REV-scale LBM (representative elementary volume scale lattice Boltzmann method) provides a possible way for the unified microscopic simulation of transscale seepage combined with pore-scale LBM. However, shown by numerical results, when simulated fluid flows in tight porous media discrete microfractures or dispersed dissolution pore, nonphysical oscillation phenomenon will occur region relatively greater velocity gradient, due to insufficient computational node caused capability constraints....
Abstract Limited CO2 resources considerably narrow down the field application of EOR for improving oil recovery in tight formation. Considering that CH4 and have similar mechanisms, CH4, as a by-product produced oil, is relatively cost-efficient agent to be injected into formation with CO2. In this work, experimental mathematical methods are proposed probe effect composition on mass transfer between CO2-CH4 gas mixture crude collected from reservoir. Experimentally, pressure-decay tests...
