Seismic Stimulation: An Eco-Friendly, Effective EOR

Jul 31, 2018 Results show that the seismic stimulation approach has been proven in carbonate, sandstone, and diatomite formations. The method is most effective in mature oil fields with a gas/oil ratio of less than 2,000 scf/bbl; an API gravity higher than 13°, and that display a high degree of heterogeneity and bypassed oil.

Reservoir Simulation Used to Plan Diatomite Development in

Diatomite reservoirs have a large concentration of oil per acre due to a high porosity, reservoir thickness and oil saturation. High viscosity at reservoir temperatures and 1-10 md permeability prevent the formation from being produced by conventional means, and operators have started producing by cyclic steam stimulation (CSS).

Thermo-Hydro-Mechanical Responses of Fractured Diatomite

ABSTRACT: We developed a numerical model to simulate steam-water injection into fractured diatomite formations. To mitigate the high nonlinearity in both the EOS of the water substance and the behavior of a fracture-matrix system, our formulations are simplified from actual system behavior but preserves the most fundamental behaviors of the steam-water fracture-matrix system.
