Schlumberger introduced the Quanta Geo photorealistic reservoir geology service for nonconductive OBM systems. The resolution of its micro-resistivity imaging is as high as leading WBM imagers, while its circumferential coverage is even greater. Field-tested in over 60 wells, it has provided high-resolution images in OBM with oil/water ratios from 60/40 to 90/10, in diverse formations including shales, high-resistivity carbonates and low-resistivity sandstones. A completely new technology has been engineered from the ground up to generate photorealistic images of reservoir geology with core-like detail, covering almost the entire borehole—as much as 98% in 8-in. holes. Due to the sond new design, it can record high-definition image data while running the tool into the hole. No other borehole imaging service today has this unique downlogging capability.
