From hydrocarbon reservoirs, brine is produced as a waste material, which may be injected into the ground or discharged at the surface. When the wastewater is injected into the ground, it may be mixed with fresh-water sources by several processes. Groundwater contamination from leakage, spills, or the injection of hazardous or toxic materials is widely regarded as one of the leading environmental problems. This study presents the use of genetic algorithms (GAs) as a viable means of estimating the transport parameters such as dispersivity, retardation factor, and diffusion coefficient of water-saturated porous media. The unknown transport parameters of advective-dispersive contaminant equations for homogeneous, linear, radial, and fractured systems are predicted by the use of GAs coupled with the experimental data. The parameter estimation study is considered as a constrained optimisation problem by minimising the total error between the calculated and the measured effluent concentrations satisfying state equations, boundary conditions, and limits on parameters.

The application of artificial neural networks for the prediction of water quality of polluted aquifer Gumrah, F; Oz, B; Guler, B; Evin, S (2000-04-01) From hydrocarbon reservoirs, beside of oil and natural gas, the brine is also produced as a waste material, which may be discharged at the surface or re-injected into the ground. When the wastewater is injected into the ground, it may be mixed with fresh water source due to to several reasons. Forecasting the pollutant concentrations by knowing the historical data at several locations on a field has a great importance to take the necessary precautions before the undesired situations are happened.
Pollution of an aquifer by produced oil field water Okandan, E; Gumrah, F; Demiral, B (2001-05-01) Brine is produced from reservoirs as a waste material from crude oil and gas after processing. Waste water may be discharged at the surface or reinjected underground. When it is reinjected, it may be mixed with an underground fresh water source for several reasons. From this point of view, forecasting the pollutant concentrations by knowing the historical data at several locations on a field has great importance when planning the necessary precautions for environmental safety.
Development of expert system for artificial lift selection Aliyev, Elshan; Sınayuç, Çağlar; Department of Petroleum and Natural Gas Engineering (2013) During the reservoir production life reservoir pressure will decline. Also after water breakthrough the fluid column weight will increase as hydrostatic pressure will increase because of increased water and oil mixture density. In this case, reservoir pressure may not be enough to lift up the fluid from bottom to the surface. These reasons decrease or even may cause to stop flowing of fluids from the well. Some techniques must be applied to prevent the production decline. Artificial lift techniques are appl...
Dynamic response analysis of the machine foundations on a nonhomogeneous soil layer Aşık, Mehmet Zülfü (1999-01-01) Real modulus of elasticity of the soil usually increases with the depth of the soil due to the increase in overburden pressure. Therefore, incorporation of the effect of the soil inhomogeneity in the formulation to obtain the response of the machine foundations is an important and a necessary step. In this paper, equations that govern the dynamic behavior of the machine foundations and consider the inhomogeneity of the elastic foundation, particularly for Gibson type soil are derived by using variational pr...
An Experimental study on steam distillation of heavy oils during thermal recovery Tavakkoli Osgouel, Yashar; Parlaktuna, Mahmut; Department of Petroleum and Natural Gas Engineering (2013) Thermal recovery methods are frequently used to enhance the production of heavy crude oils. Steam-based processes are the most economically popular and effective methods for heavy oil recovery for several decades. In general, there are various mechanisms over steam injection to enhance and have additional oil recovery. However, among these mechanisms, steam distillation plays pivotal role in the recovery of crude oil during thermal recovery process. In this study, an experimental investigation was carried o...
