ay-Ionizing technology is a short intense bursts of electromagnetic energy with enough penetration power. Shale’s contain much radioactive material while sandstone, limestone and dolomite contains very little. The borehole only potential old bearing well is traversed with a sensing device that can detect and measure the intensity of Gamma Ray and plot them on a continual basis vertically.The formations with high radioactive are shale’s and those with a low radioactive, are maybe potential oil bearing zones. Gamma radiation survey uses a sensing device that can delineate a high to low radioactive from a horizontal attitude on the surface.
The interpolation between adjacent data allows the definition of a section of electrical resistivity (exactly as in the case of a geoelectric resistivity section). The magnetotelluric surveys reach great depths in confined spaces. They are used in general to define the geological and hydrogeological setting for the following applications: Definition of structures of deep gravitational instability; definition of geological and tectonic structures; definition of geothermal, hydro‐geological and hydrocarbonmodels for the optimal location of wells.
Passive Seismic Tomography (PST) inversion utilize P and S-wave travel times from natural micro-earthquakes, to accurately estimate 3D Vp (structural) and Vp/Vs (lithologic) information of the subsurface and its potential starting from a monodimentional input velocity model. Passive Seismic Tomography PST has been used in the past for seismological reasons on a different and certainly larger scale than that of hydrocarbon or geothermal exploration. The quality of results and the advantages over conventional seismic, clearly indicate the benefits of this method, in oil, gas and geothermal exploration, delineation and even better during production when the input velocity model is well known.
Near-vertical fault or interface seismic signal is typically scattered by these interfaces. In contrast, gravity, MT and AMT have their best imaging at vertical interfaces across which lateral density or magnetic susceptibility contrasts exist. Different exploration methods are vital for helping operators providing independent corroboration of total volume and shape hydrocarbon potential. Seismic data quality can be significantly improved with gravity, MT, AMT, passive seismic and micro seismic tomography results to improve and refine the seismic velocity model. Without constraining information, a gravity model can be modified in an infinite number of ways in order to match the observed gravity signal.
