Weatherford introduced the compact oil-based-mud (OBM) microimager (COI), a slim-profile tool that delivers fullbore, high-definition images in wells drilled with oil-, diesel-, or synthetic-based muds. The tool’s 4.1-in. diameter enables deployment in a wide range of geometries including narrow, horizontal, and highly deviated wells. The COI features eight pads with 72 total measurement electrodes that provide optimum coverage. The images can be enhanced further through Weatherford Reveal 360 image processing. Reveal 360 technology uses structural and textural information in the measured parts of the image to reconstruct any gaps between pads. Through analysis of the COI images, the structural, stratigraphic, and depositional geology around the wellbore can be detailed, even in wells previously deemed too complex for imaging services. Recently, the COI was deployed with other petrophysical-measurement tools in an 8¾-in. OBM well in Latin America. The COI captured superior images of the geology compared with incumbent technology, which enabled detailed fracture analysis and stratigraphic interpretation. As a result of the image and interpretation services, the operator was able to reduce reservoir uncertainty and to optimize the completion design.
