Liberty Oilfield Services provides unsurpassed knowledge regarding fracture growth behavior and its impact on production performance, acquired through a pursuit of real-data analysis and decades of experience with calibrated fracture growth and reservoir modeling.
Liberty’s frac designs focus on how we can help our customers make better wells for less. We consider many factors such as rock mechanics, wellbore design, fluid dynamics and chemistry, past observations of fracture growth behavior from fracture mapping and net pressure history matching, production response in neighboring wells, and the overall requirements for the reservoir for the desired proppant conductivity and placement.
Liberty Oilfield Services can help you to:
Evaluate completion and production trends in a specific area using one of our extensive databases for US liquid-rich basins in conjunction with detailed multi-variate analysis. This provides a useful “big picture” starting point for any frac design.
Review past frac experience to determine critical design issues, problem areas, additional data requirements, and develop a frac design generating a reduction in $/BOE.
Assist in the coordination and evaluation of laboratory and field tests required to support the stimulation program.
Perform analysis of diagnostic data (DFIT’s, mini-frac and other injections) to obtain basic analysis anchor points and to help estimate achieved fracture dimensions.
Conduct fracture model calibration that ties in directly measured fracture dimensions with net pressure history matching, to provide a fracture design tool that is tied to real measurements.
Perform production data analysis and reservoir modeling. Evaluate and reconcile well production response and evaluate production sensitivities to frac design and wellbore placement changes.
At Liberty we live to frac, and frac efficiently. To ensure efficient operations and maximization of pump time versus downtime, Liberty is on the forefront of operational and equipment innovation. We have a strong focus on safely improving efficiencies through our more experienced personnel and redundancies in backup equipment.
While our frac design expertise helps making you better wells, Liberty Oilfield Services superior service quality helps to bring your well on production faster.

Liberty is helping provide a new technical perspective to Bakken completions. We have significantly improved production using our unique insights in fracture growth behavior in unconventional resource plays through our extensive fracture mapping and fracture analysis experience.
In ultra-low permeability shale gas reservoirs as the Barnett shale, the main key to economic production response through hydraulic fracturing was to create fracture complexity. Low-viscosity slickwater treatments encouraged this complex fracture growth in a reservoir where the natural fracture orientation was roughly orthogonal to the preferred fracture plane. In the moderate-permeability liquid-rich Bakken formation, we are not so lucky. Fracture complexity is more driven by the nature of the completion, making it tougher to create a complex network. In addition, the higher permeability of the formation requires that the fracture system comprises sufficient conductivity. Therefore, in the Bakken formation, a focus on complexity and conductivity is key to high production.
