MRIL®-WD™- Sensor

Primary applications for Sperry Drilling services' MRIL®-WD™ magnetic resonance imaging logging-while-drilling tools are in high-cost offshore and onshore exploration and development wells. In these wells, breakthroughs in reservoir characterization have been achieved in directly determining hydrocarbon volumes, net permeability feet and hydrocarbon type, thus circumventing the amount of rig time required to obtain wireline data.



  • Real-time identification of free- and bound-fluid volumes
  • Lithology-independent porosity measurement
  • Identification of free-fluid type: gas, oil or water
  • Permeability indication
  • Real-time evaluation of high-cost exploration wells
  • Comprehensive reservoir evaluation from LWD in high-angle and horizontal wells

Summary Summary West Africa: InSite AFR™ Sensor Delivers High-Resolution Images for Reservoir Fracture Characterization Sign in required
Acquire high-resolution borehole images while drilling the wells to characterize the fractures and rock texture in order to predict injector performance.
Summary Summary UAE: First Geo-Pilot® Dirigo Rotary Steerable Run in UAE Lands Complex Sign in required
An operator planned the first fork-type multilateral well design in the United Arab Emirates (UAE) to be drilled from an offshore platform. The complexity of the program would require advanced geosteering capabilities to achieve maximum reservoir contact and precise placement of the forked-shape laterals with full accessibility for well intervention. The target was just 600 feet (183 meters) south of the platform and required a “pregnant lady” well profile through a very challenging shale formation where historically no directional work is recommended. With only one available platform slot, located on the northwest side, the well would first have to be nudged and turned in the 16-inch hole in order to reduce surface collision risk, and would then encounter a channel at the 13-3/8-inch casing point known to cause huge losses. In the 12 ¼-inch hole, a required open-hole sidetrack would present yet another challenge. And furthermore, the 8-½-inch lateral interval would have to be maintained within the reservoir target of just two feet (0.61 meters) in thickness.
Summary Summary Gulf of Mexico: Sperry Drilling Configures MRIL-WD™ Sensor for Logging High Permeability Formations with Shorter Exposure Times Sign in required
In this reservoir evaluation application, Sperry Drilling services was challenged to provide a solution for distinguishing invading fluids of synthetic oil based mud (SOBM) and native hydrocarbons in high permeability formations with high exposure times.
Summary Summary Mexico: Operator Saves Time USD 7.5 Million in Deepwater Rig Time by Acquiring Crucial Formation Evaluation Data in Real Time Sign in required
