Advantageous Reservoir Characterization Technology in Extra Low Permeability Oil Reservoirs

Study on Stochastic Flow in Low Permeability Sandstone Oil Reservoir

Reservoir porous medium is random, in terms of oil and gas for low permeability reservoirs. Consider the random nature of the reservoir will enable to improve the accuracy of numerical reservoir simulation. Based on extensive research, for the stochastic nature of the reservoir from the two aspects of physical simulation, numerical simulation, the relevant international studies were reviewed. T...

Reservoir Characterization of Pennsylvanian Sandstone Reservoirs

Analysis of bacterial diversity in two oil blocks from two low-permeability reservoirs with high salinities

The community diversities of two oil reservoirs with low permeability of 1.81 × 10(-3) and 2.29 × 10(-3) μm(2) in Changqing, China, were investigated using a high throughput sequencing technique to analyze the influence of biostimulation with a nutrient activator on the bacterial communities. These two blocks differed significantly in salinity (average 17,500 vs 40,900 mg/L). A core simulation ...

A new investigation on modeling of permeability reduction during CO2 flooding processes in sandstone oil reservoirs

Permeability reduction in oil reservoirs during primary oil recovery and using the enhanced oil recovery methods are complicated problem which most of the oil field in worlds has encountered. In this work, a modified model based on four phase black oil model (oil, water, gas, and asphaltene) was developed to account permeability reduction during CO2 flooding in cylindrical coordinates around a ...

Technical and Economic Evaluation of Oil reservoirs in The Form of Optimal Management of Reservoir Development (Case Study of Asmari reservoir in One of Iranian southwest Oil Fields)

Technical and economic evaluations in an oil field means that by different technologies and correct planning, maximize the amount of extraction of hydrocarbons and minimize risks and costs. The current research includes technical evaluation and economic analysis on one of the undeveloped reservoirs in the southwest of Iran. The amount of recoverable hydrocarbon was estimated using the Monte Car...
