SLB wireline openhole logging delivers reservoir data operators can act on without coring the entire well. Whole core remains the highest-resolution source for guiding and constraining reservoir models, but coring every foot of a well is rarely practical, and seismic data alone does not resolve the detail subsurface teams need.
Wireline openhole logging closes that gap. SLB deploys sensors that measure porosity, lithology, fluids, pressure, and geomechanics in situ and in real time, across the full range of formation conditions, in a single wireline trip. SLB delivers these measurements workflow-ready, so subsurface teams can refine reservoir models and make completion and development decisions with less uncertainty and lower operational risk.
SLB deep transient testing performed with the Ora™ intelligent wireline formation testing platform and Quanta Geo™ photorealistic reservoir geology service delivered more than 10,000 bbl/d in estimated production and cut CO2e by 96% compared with conventional testing.
The Sonic Scanner™ acoustic scanning platform, Quanta Geo service, and 3D far-field sonic service mapped natural fractures up to 40 ft from the wellbore, including fractures that standard microresistivity imaging did not capture. The insight improved the operator’s completion design.
SLB digital workflows performed with the Ora platform delivered actionable reservoir insights in just 48 hours, down from the 2 to 4 weeks required by conventional formation-evaluation methods. The accelerated workflow helped the operator save considerable rig time.
A CCS-focused mechanical earth model, calibrated with the Sonic Scanner™ platform, MDT™ modular formation dynamics tester, and Quanta Geo™ service, supported Class VI CO₂ well permitting for Minnkota Power Cooperative with more than 8,800 ft of core-like microresistivity images.

The SLB MaxPull™ high-pull wireline conveyance system pulls up to 30,000 lbf, enabling operators to log wells deeper than 36,000 ft on wireline instead of resorting to costlier drillpipe or coiled tubing conveyance.
Explore the MaxPull systemSLB wireline openhole logging measures porosity, lithology, fluid properties, formation pressure, and geomechanical properties directly in the reservoir. Sensors are conveyed on wireline and record data in situ and in real time, without requiring a full core of the drilled interval.
Whole core provides the highest-resolution reservoir data, but coring an entire well is rarely practical. Wireline openhole logging captures petrophysical, geomechanical, and fluid data across the full wellbore in a single trip, reducing the time and cost of continuous coring.
Yes. SLB wireline formation testing platforms, including the Ora™ intelligent wireline formation testing platform, combine formation pressure measurement, downhole fluid analysis, fluid sampling, and sidewall coring in a single wireline run.
SLB offers the Platform Express™ integrated wireline logging tool for standard wells, the SlimXtreme™ slimhole logging platform for restricted-diameter wellbores, and the Xtreme™ HPHT well logging platform for high-pressure, high-temperature environments.
Wireline openhole logging delivers workflow-ready porosity, lithology, pressure, and geomechanical data that reduces uncertainty in reservoir models. This supports more informed completion and development decisions and reduces the operational risk of drilling and coring the full well.
