Cordax's LWT (Logging-While-Tripping) tool gathers openhole formation evaluation (FE) data in the lateral. It adds little risk to drilling operations as data is collected during standard tripping (pulling out of hole) operations and does not require alteration of drilling plans or extra rig time to install a specialized BHA, meaning it can run in vertical, horizontal, and highly deviated wells. It can also be run after a reamer run or a dedicated LWT run as needed.

Cordax's ZoneGrader uses the available drilling and mud-log data together with acquired LWT FE data to calculate petrophysical and geomechanical rock perperties along the wellbore. It provides supplementary information towards developing earth models at relatively low cost.

Cordax's ZoneTuner product is a lateral completion optimization software application that uses mechanical stress calculated from log data to find the points along each stage where the stress is most consistent. The objective is to allow engineers to design the completion of the well with the purpose of allowing the pumped materials to be distributed more evenly at the point of hydraulic fracture inititation.

Price per well

• LWT tools are pumped down drill-string into steel and composite collars after reaching TD
• Memory-based logging data collected while normally tripping up the wellbore
• Tool stay inside drill pipe while measuring, very limited LIH risk. Over > 710 runs zero tools LIH.
• Depth registration is more accurate and smoother than LWD

Three modes of operation:

• LWT in last bit run; LWT collars above the mud motor
• LWT during reamer run; LWT collars below the reamer
• Dedicated LWT run

• Openhole formation evaluation: gamma ray, spectral gamma ray, compensated neutron, compensated density, dual-induction resistivity, laterolog resistivity, propagation resistivity
• Calculated omni-directional caliper log
• Neural-net-based calculated sonic log
• Logs result from API calibrated measurements
• Basic interpretation
• Advanced interpretation for geomechanics evaluation
