Aquifers,which play a prominent role as an effective tool to recover hydrocarbon from reservoirs,assist the production of hydrocarbon in various *** so-called water flooding methods,the pressure of the reservoir is intensified by the injection of water into the formation,increasing the capacity of the reservoir to allow for more hydrocarbon *** studies have indicated that oil recovery can be increased by modifying the salinity of the injected brine in water flooding ***,various characteristics of brines are required for different calculations used within the petroleum ***,it is of great significance to acquire the exact information about PVT properties of brine extracted from *** properties of brine that are of great importance are density,enthalpy,and vapor *** this study,radial basis function neural networks assisted with genetic algorithm were utilized to predict the mentioned *** root mean squared error of 0.270810,0.455726,and 1.264687 were obtained for reservoir brine density,enthalpy,and vapor pressure,*** predicted values obtained by the proposed models were in great agreement with experimental *** addition,a comparison between the proposed model in this study and a previously proposed model revealed the superiority of the proposed GA-RBF model.

The Controversial Genesis of Thermogenic Gas-A Polemical Article

Journal of Environmental Science and Engineering(A) 2022年第4期11卷 101-120页

作者： Andrzej Pawuła Institute of Geology Adam Mickiewicz UniversitySenior Academic LecturerPoznań61-712Poland

The article contains a critique of the biogenic theory of natural gas,which incorrectly combines the phenomenon of methane formation in the anaerobic process of decomposition of organic matter with the phenomenon of methane expulsion in the process of pyrolysis and *** view of the organic origin of methane is treated as a paradigm,despite the lack of thermal conditions to induce *** mineralized organic substance for which the name“kerogen”was created undergoes the process of carbonization and this process,under the conditions of the deposit,is a one-way *** paradox of the petroleum geology methodology is the determination of the oil potential from the TOC(Total Organic Carbon)in the *** reservoir conditions,methane is produced by chemical reactions of igneous gases,mainly hydrogen,carbon and *** elements are formed in the process of hot plasma recombination in zone D and the formation of basalt *** change in the structure of matter causes stresses in the rock mass and the formation of igneous *** lowering the temperature of post-igneous solutions,the release of igneous gases and a rapid increase in pressure *** the created dislocation zones tectonic pressure in natural gas deposits is more than twice the hydrostatic *** process of the evolution of igneous gases and reactions between them are,among others,methane explosions in hard coal *** inorganic origin of methane also has a positive aspect,the conclusion is that natural gas resources are renewable and that they are ubiquitous.
