investigation of underground gas storage in a partially depleted naturally fractured gas reservoir

Investigation of Underground Gas Storage in a Partially Depleted Naturally Fractured Gas Reservoir

In this work, studies of underground gas storage (UGS) were performed on a partially depleted, naturally fractured gas reservoir through compositional simulation. Reservoir dynamic model was calibrated by history matching of about 20 years of researvoir production. Effects of fracture parameters, i.e. fracture shape factor, fracture permeability and porosity were studied. Results show...

Underground Storage of Natural Gas in Indiana

Underground gas storage is the practical means of making available the increased supplies of natural gas that are needed in Indiana in winter periods of peak demand. To date, 21 gas storage projects providing an estimated storage capacity of 48 billion cubic feet have been initiated. Expansion of storage capacity is anticipated. Basic geologic factors and availability of subsurface information ...

Immiscible Gas Injection to Improve Recovery from an Iranian Naturally Fractured Reservoir: a Case Study with Emphasis on Uncertain Parameters

A Numerical Investigation into the Effect of Controllable Parameters on the Natural Gas Storage in a Weak Reservoir-type Aquifer

Natural gas storage process in aquifer, due to fluid flow behavior of gas and water in the porous medium and because of their contact with each other under reservoir conditions, faces several challenges. Therefore, there should be a clear understanding of the injected gas behavior before and after the injection into the reservoir. This research simulates the natural gas storage in aquifer by us...

Reservoir characterization in an underground gas storage field using joint inversion of flow and geodetic data

Characterization of reservoir properties like porosity and permeability in reservoir models typically relies on history matching of production data, well pressure data, and possibly other fluid-dynamical data. Calibrated (history-matched) reservoir models are then used for forecasting production and designing effective strategies for improved oil and gas recovery. Here, we perform assimilation ...

Critical Parameters Affecting Water Alternating Gas (WAG) Injection in an Iranian Fractured Reservoir

Microscopic oil displacement of water flooding and sweep efficiency of continuous gas injection could be improved by water alternating gas (WAG) injection. The WAG injection process aims to squeeze more oil out of the reservoirs; in this method, water and gas are alternatively injected into the reservoir. Also, availability of hydrocarbon or CO2 gases in the field makes it attractive for gas-ba...
