Effective Transmitter Amplifier Design for Detection of Off-Shore Scaled Oil Reservoirs

摘要

Sea Bed Logging (SBL) is a use of the marine controlled source electromagnetic (CSEM) technique that is utilized to recognize potential nearness of hydrocarbon by utilizing a Horizontal Electric Dipole (HED) reception apparatus. It is liable to produce EM waves and accepting them through batch of sea floor electric field receivers. This method sometime has been vastly opted to diminish the element of inaccurate mapping that leads to false drilling at locations causing massive amount of capital loss and time. Marine EM equipment development continues to be an active research and development area for both industry and academia. In order for the miniaturization of such circumstances several modifications can be made to the instrumentation for the improved and more efficient outcomes. Along with other elements involved in the process, amplifier specially has its own relevance and yet can be enhanced further for the better propagation and improved performance of transmitters. After careful calculations, the seabed model has been mimicked in lab scale tank comprising of under-burden layer, over-burden layer, hydrocarbon reservoirs and sea water. An amplifier system is designed especially for the current experimental setup. The effect was studied under application of multiple frequencies upon which various gains were also obtained. The promising response reveals that by concentrating on the amplifier system, potential oil reservoirs can be explore more efficiently.
