Disposal of concentrate from brackish water desalination plants by deep well injection into oil and gas fields is an attractive option in Texas. Underpressured depleted oil and gas reservoirs cover large areas of the state. Six areas were selected from across Texas for detailed analysis. These sites were characterized by abundant brackish groundwater, a projected shortage of freshwater, deplete...

core flooding experiments were conducted with the objective of evaluating near miscible surfactant alternating co2 injection and the effect of surfactant concentrations on gas-oil and water displacements in porous media. the core samples were provided from a low permeability mixed wet oil reservoir at 156 °f and 1900 psia. in addition, very few studies of surfactant adsorption on carbonate mine...

Injection of gas–liquid sprays into gas–solid fluidized beds finds application in many industries. Effective mixing and distribution liquid feed solid bed material is paramount to ensure an efficient profitable process. Despite its long-term use, the mechanism injection continues raise questions only partially understood. This paper provides a thorough up-to-date review experimental numerical i...

this research presents a mathematical model for oil and gas optimal allocation to different sectors in iran using operations research techniques. sectors are residential and commercial, transportation, industries, agriculture, exports, injection to oil reservoirs and power plans as a secondary energy producer. optimal allocation of energy resources to end-uses from 2011 to 2021 has been done us...

Low-permeability near-critical volatile reservoirs are characterized by light oil, complex fluid phase, and strong reservoir inhomogeneity, etc. Purely injecting CO2 will create a series of problems, such as serious gas channeling, low sweep efficiency, oil recovery. Therefore, in this paper, through combination experiments simulations the process studying problem from simple to complex, we car...

As the technology of enhanced oil recovery by gas injection has already been applied worldwide, the research of the transmit mechanism between injected-gas and oil is important to the optimization of gas injection plan. Diffusion is an important phenomenon during the process of gas injection displacement. Because of diffusion, gas molecules will penetrate into the oil phase, while the oil will ...
