Abstract Diminishing hydrocarbon reserves in oil reservoirs and the need to sustain continuous production have prompted researchers further investigate Enhanced Oil Recovery (EOR) techniques. Researchers also test run these processes before EOR fluid injection into reservoir maximise whilst minimising damage loss. This study aims simulate displacement during of two different types fluid, namely...

Microbial Enhanced Oil Recovery (MEOR) is a potential technology for residual heavy oil recovery. Many heavy oil fields in Oman and elsewhere have difficulty in crude oil recovery because it is expensive due to its high viscosity. Indigenous microbes are capable of improving the fluidity of heavy oil, by changing its high viscosity and producing lighter oil fractions. Many spore-forming bacteri...

Gas injection into a naturally fractured oil reservoir keeps the pressure and increments initial recovery from reservoir. The main aim of this work was to develop numerical model calculate mass transfer (molecular diffusion convection) between gas injected in fracture residual fluid (gas oil) matrix block. dual continuum is applied describe flow behaviour porous media. Finally, validated by com...

For the thick sandstone reservoir, due to gravity differentiation, water drive mainly uses bottom oil of while gas drives along top reservoir. Water-alternating (WAG) injection can effectively combine advantages flooding and injection, so that work in synergy, thus further expanding swept volume enhancing recovery. Over past half century, technology has been successfully applied more than 60 oi...

In many oil-recovery systems, relative permeabilities (kr) are essential flow factors that affect fluid dispersion and output from petroleum resources. Traditionally, taking rock samples the reservoir performing suitable laboratory studies is required to get these crucial properties. Despite fact kr a function of saturation, it now well established pore shape distribution, absolute permeability...

in this paper, the role of molecular diffusion in mobilization of waterflood residual oil is examined. a moving mesh method is applied to solve the moving interface problem of residual oil blobs swelling by co2 diffusion through a blocking water phase. the results of this modeling are compared with experimental results of a 2d glass micromodel experiment. although, the solution method is applie...

In this paper, a new model based on the thevenin equivalent circuit for investigating the ultra-saturation phenomenon during the energization of a loaded power transformer is presented and its effect on the differential protection of the transformer is considered. The ultra-saturation phenomenon causes the mal-operation of the power transformer differential protection. So, the description a...

OBJECTIVE The objective of this study was to evaluate the intake and nutrient digestibility, nitrogen balance and ruminal ammonia nitrogen in lambs of diets containing different levels of residual frying oil. METHODS Levels of 0, 20, 40, 60, and 80 g/kg dry matter (DM) base of residual frying oil in the diets of lambs were evaluated. Five castrated lambs with initial body weights of 36.8±3.3 ...

PURPOSE To evaluate safety and efficacy of using Siluron2000 silicone oil in the treatment of full-thickness macular hole by comparing its propensity to emulsify with emulsification of the "gold standard" Siluron5000, and to assess safety and efficacy of F4H5 (perfluorobutylpentane) in removing emulsified oil droplets from the eye. METHODS A single-center, randomized controlled parallel group...
