Geosynthesis — Modern Origin of Hydrocarbons and Practical Use of This Phenomenon Aspects in Oil and Gas Development

Abstract

Theoretical and experemental research of hydrocarbon's origin gave us consideration, that the origin of oil and gas is not only long geological process, but also a modern phenomenon (biosphere concept), which is closely associated with the geochemical cycling of carbon in carbon dioxide CO₂ through the Earth's surface with meteogenic waters. One of the main in this phenomenon is the process (unknown earlier) of decomposition of carbonated water on the surface of mechanically activated matrix of rocks, which occurs with formation of hydrogen and low temperature synthesis of hydrocarbons (geosynthesis - geological synthesis) from CO₂ and water. These assumptions are confirmed by our experiments on author's and certified laboratory facilities in stationary and dynamic modes. In the experiments, in a role of rock's “activator” we used an iron shaving. The experiments were performed at room temperature and atmospheric pressure. In both modes, the physical and chemical processes in porous media filled with carbonated water has been researched. In the dynamic mode the carbonated water was pumped at the different rate through the model. In both modes the composition of arising gases has been studied, using the chromatograph. The results of research are directly related to the technology of oil field development to maintain reservoir pressure through the CO₂ use as working fluid, as well as CO₂ disposal technology in depleted layers of oil and gas fields, and in the tertiary oil recovery in exhaustible fields, and in oil development in low permiability reservoirs. Problems of energy and environmental crises may be really reduce by using the results of this research, specifically by utilizing CO₂ as working agent.
