Abstract

Summary

The horizontal well was successfully drilled, and Geosteering objectives were achieved with 100% reservoir contact, delivering 8,000 ft. measured depth (MD) targeting four thin carbonate layers and overcoming the complex geology environment. Real-time high-resolution microresistivity images, along with at-bit resistivity qualitative measurements, assisted with detecting stratigraphic movement within the target layer before approaching the less porous boundaries. Near-bit azimuthal gamma ray helped maintain the wellbore attitude parallel to the geological stratigraphy within the sublayers as well as a smooth transition from one sublayer to the next, minimum borehole tortuosity aided by the point-the-bit RSS, and at-bit inclination.
