... microsphere flow experiment microsphere suspension reservoir enhanced oil recovery Introduction With many oilfields entering the high water cut development stage, a variety of chemical flooding methods have been successfully applied to enhance oil recovery ( Sydansk et al., 2004 ; Sui et al...

..., to simulate oil production in the middle of the reservoir it was concluded that low rate waterflooding is needed in laboratory tests to allow spontaneous imbibition into the matrix to displace oil by positive capillary forces. The combination of using oils that differ in viscosity in different injection...

... The Marrat reservoir consists of mainly oolitic grainstone and packstone and is primarily the uppermost portion of Marrat "C" unit in the south. The rest of the limestone is mainly micritic with scattered packstone, wackestone and some grainstone. The depositional environment of the Marrat "C...

... for injection into reservoirs. Second, fly ash nanoparticles were used to measure the synergy between nanoparticles and surfactants in the creation of oil-in-brine emulsions. Third, the emulsion stability was tested using a microscope and a rheometer with three different surfactants (cationic, nonionic...

... down to the near basement. Reservoir Isochore Generation The C2hl reservoir is very thin, 0-30 m with an average of 10 m, compared to the overall stratigraphy and total model thickness and is also at or below vertical resolution of seismic data in the best case. This makes construction of model...

... Abstract Conventional hydrothermal ("low enthalpy") geothermal reservoirs are already being developed in the Netherlands as a source of heat for greenhouses, district heating. Many of these wells are left with a positive skin after being drilled, and could therefore benefit from stimulation...

...Introduction CO2 can be injected into the reservoir under either miscible or immiscible conditions, depending on the pressure (p), temperature (T) and composition of the system. In a miscible CO 2 flood, gas and oil form one phase which greatly improves displacement efficiency and oil...

... The reservoir injection simulation is performed with a GEM model, which provides the pressure and temperature distributions that are input into the geomechanical model. The injection history requires a number of steps for which the elastic response is computed. The critically stress area...

... the displacement mechanisms by CO 2 injection. Using the geological parameters collected for Karaganda Coal Basin, main factors affecting methane production including different rates of CO 2 injection and different starting times of CO 2 injection were simulated and compared. CO 2 injection into CBM reservoir...

... The polymer flooding technique was improved continuously in the process of industrial applications. Till now, the integrated supporting techniques regarding the reservoir engineering, oil production engineering, surface engineering and dynamic monitoring have been formed based on a series...

...Characterization of reservoir rock and fluids (Thursday) Abstract Smart water injection (SWI) and carbonate water injection (CWI) have been successfully used in enhanced oil recovery (EOR) due to favorable crude oil-brine-rock interactions. In this study, these two EOR methods are combined...

... forecasting, numerical reservoir models and "digital twins" of reservoirs have been used for decades. However, increasing computing power and Artificial Intelligence recently enabled oil and gas companies to generate "digital siblings" of reservoirs (model ensembles) covering the uncertainty range in static...

... Abstract Germik, a mature heavy oil field in Southeast Turkey, has been producing for more than 60 years with a significant decline in pressure and oil production. To predict future performance of this reservoir and explore possible enhanced oil recovery (EOR) scenarios for a better pressure...

... by a homogeneous reservoir model, or numerically by a heterogeneous reservoir model. Results of simulation by a homogeneous model lead to quantitative estimates of reservoir transmissibility σ app and diffusivity χ app in the cross-well space, which are called "apparent". The term "apparent" means...

... TOC effect on CO 2 -rock wettability for the real reservoir sandstone samples with a range of TOC (0.01 wt %, 0.015 wt %, 0.017 wt %, and 0.019 wt % TOC) at various pressures (5 MPa, 10 MPa, 15 MPa, and 20 MPa) and a temperature of 334 K was systematically tested. The results reveal...

..., and hence it helps in improving sweep efficiency. However, one of the critical encounters when using foam in reservoirs is the adsorption of the surfactant on the rock surface. The loss of surfactant to the rock surface will lead to destabilizing the foam and accelerating the collapse rate of foam films...
