Do you have enough formation information to plan your completion and tailor your stimulation?

Our Solution

With the proliferation of unconventional and horizontal resource drilling, optimizing production has become has become progressively more challenging for operators. Openhole log data is a key component in a successful completions strategy as it facilitates the understanding of important reservoir characteristics such as:

  • variability and composition of reservoir in lateral well bores

  • petrophysical and geomechanical properties of reservoir rock

  • complex geology effects on well completions

  • effects of clays on completion and stimulation

Our Solution (Continued)

Pre-set geometric completions and stimulation designs do not factor in these critical well characteristics. Logging While TrippingTM (LWTTM) services, when combined with Zone GraderTM analysis and interpretation allow you to make informed completion decisions using real openhole data and enhance the producibility of your reservoir. By understanding the petrophysical and mechanical properties of your well a customized completion can be developed to tailor your stimulation program and save costs. This fine tuning of each stage and frack cluster improves effectiveness and saves costs by right-sizing your completion budget. Don't settle for after-the-fact cased hole logs or derived well information from non-logging measurements or offset wells.

Operationally, the safe and economic acquisition of openhole logs is as critical as the data itself. Cordax Evaluation Technologies provides formation evaluation solutions using the Logging While Tripping (LWT) platform. This patented logging technique allows memory based openhole logs to be acquired in a method that is more cost effective, uses less rig time, and has fewer inherent risks than wireline, shuttle (thru-the-bit), or logging-while-drilling (LWD) methods. LWT enables openhole logs to be acquired in vertical, deviated, horizontal and tough logging condition wells where logging was previously considered too risky or too expensive

The real cost of openhole logging is the incremental rig time used in conveyance and acquisition. LWT acquires wireline quality data while essentially eliminating this considerable expense and mitigating operational risk.


'Hundreds of new-generation production logs have been run in geometrically completed unconventional wells. Analyzing these logs indicates that 15-20% of the fracture stages and 35-40% of the perforation clusters do not contribute to production.'
