Fine numerical simulation of deep carbonate gas reservoir in northwest Sichuan

fine grid simulation study of gas injection in one of iranian carbonate reservoirs

a typical iranians carbonate matrix block surrounded by an open fracture was modelled in order to understand the fracture-matrix interaction and how to model the interaction best. this was modelled by using a fine-scaled eclipse model in the single porosity mode . the model was extended to a stack of 6 matrix blocks to understand block-to-block interaction under gas injection scenarios. results...

Numerical modeling of hydraulic fracturing in carbonate rocks of Bangestan reservoir

Hydraulic fracturing is used in the oil industry in order to increase the index of production and processing in the wells whose efficiencies have been dropped due to a long-term harvest or the rocks around the wells are of low permeability. Since the hydraulic fracturing operation is costly, it is of special importance to the project managers to determine the pressure required for hydraulic fra...

AN EXPERIMENTAL INVESTIGATION OF GRAVITY DRAINAGE DURING IMMISCIBLE GAS INJECTION IN CARBONATE ROCKS UNDER RESERVOIR CONDITIONS

Gravity drainage is one of the important recovery mechanisms in fractured carbonate and conventional reservoirs. It occurs due to density difference between the gas in fracture and the oil in matrix as well as in conventional tilted reservoirs. Oil phase will form films which are produced under gravity forces (film flow). Many gas injection experiments have been done on laboratory scales with d...

Genetic Model for Gas Reservoir Simulation

ABSTRACT: A general application model applied to gas reservoir simulation merging elements of the evolutionary and object-oriented paradigms is shown. The model works in three ways: 1. Make an adaptive grid partition of the 3D structure based on a non-linear function. 2. Solve the non-linear algebraic equation systems in each block, which are generated for the gas properties calculation, taking...
