Liberty Launches Fracture Diagnostic Service

Read Time: 1 min

Liberty Oilfield Services has launched FracSense, a diagnostic service to help exploration and production acquire more accurate diagnostic well data to optimize hydraulic fracture completions and well spacing.

Launched in partnership with OptaSense, the diagnostics service utilizes real time fiber optic measurements to monitor per stage fracture placement and frac hits in offset wells. Since the technology can be conveyed via wireline, it can also be used to profile production in producing wells.

James Pollard, managing director of OptaSense, said: “The ability to optimize frac design based on reservoir and production response delivers considerable value. OptaSense’s fiber-optic measurements, delivering real-time data and visualization, along with Liberty’s hydraulic fracturing stimulation and completion design expertise, will help operators maximize resource recovery in their reservoirs.”

Capturing high resolution data significantly shortens the learning curve for actionable change for operators. FracSense measurements provide per-stage information about fracture azimuth, stage spacing coverage and perforation cluster design and their impact on cluster efficiency. Fluid and proppant volume to first frac hit response improves fracture length and fracture height model calibration as well as evaluating effective well spacing. The data also allows Liberty to help operators determine diversion techniques or alternate stage spacing, as well as to fine-tune perforation designs for optimal cluster efficiency in real time.
