Recent advancements in deep and ultra-deep designs and data inversion algorithms have also taken enabled new applications such as 3D fault mapping, 3D fluid and lithology mapping and far-field formation evaluation. The large number...

... Abstract Sensitivity of the electromagnetic (EM) field to resistivity ahead of the bit has been proven for Ultra-Deep Azimuthal Resistivity (UDAR) tools, and is actively being used in near vertical wells along with 1D inversion. Inverting for resistivity ahead in horizontal wells would allow...

... Abstract We put forward a high-resolution seismic inversion workflow to improve vertical resolution, making it possible to identify reservoirs within 10m. We employed this workflow in Ordos Basin for delineating tight gas. Our research is based on improving the vertical resolution...

... in real time to the desired formations. Traditionally a multi-layer 1D geological model is constructed by inversion algorithms utilizing five measurement components of the EM signal. Recent advances in tool designs and computational capabilities enabled the utilization of the full nine EM measurement...
