۲D Simulation of Shale Gas Reservoir through Z-Axis Tipper Electromagnetic Data

Shale gas, an unconventional natural gas resource abundant in organic matter, has gained significant attention in global natural gas exploration as a crucial supplement and alternative to conventional natural gas sources. Due to higher electrical resistivity of oil traps in conductive sedimentary backgrounds, shale gas reservoirs are ideal targets for geophysical studies to be explored, whereby the Z-axis tipper electromagnetic method (ZTEM) can be employed to simulate and model their geoelectrical responses. The study conducted involved the utilization of an airborne method, a tool that relies on natural source transmitter, to simulate shale gas reservoirs. Initially, geoelectrical models of shallow shale gas reservoirs were constructed for three different simple geological scenarios, followed by the generation of responses through an airborne geophysical survey. The assumed electrical resistivity models were effectively reconstructed by applying an inversion algorithm to the data. This process proved to be successful in accurately representing the physical characteristics of shale gas reservoirs. As a result, this innovative tool offers the capability to rapidly explore vast areas with high potential for shale gas reserves, enabling the identification of valuable targets efficiently. The combination of advanced technology, numerical modeling and geological expertise allows for the expedited discovery of significant resources in the field of shale gas exploration.
