Understanding and Optimizing Hydraulic Fracturing
(PTRT2015)

Description:
Hydraulic fractures are the key to development of most low permeability reservoirs, yet fractures are frequently mischaracterized and poorly optimized.  This course will focus on practical techniques to investigate and optimize fracture treatments.  Instead of relying solely on theory and model forecasts, this course challenges conventional wisdom by focusing on irrefutable field evidence demonstrating fracture deficiencies.  Participants in this course will have access to over 200 published field studies in which the productivity and profitability of fields have been improved by altering the treatment design.  Participants are encouraged to bring frac designs from their fields for brainstorming throughout the seminar. 

Although it is mathematically convenient to describe fractures as simple, vertical, planar features of predictable width and hydraulic continuity – this oversimplified mindset often prevents operators from designing optimal well completions.  Fracture geometry is frequently complex, with imperfect lateral continuity.  Fluid flow regimes are complex – often causing pressure losses 100-times higher than predicted from published conductivity data.  Reservoirs contain heterogeneities such as boundaries, laminations and anisotropic permeability that influence frac growth and performance.  This seminar will help participants gain an understanding of the simplifications made by many industry models and the required design changes to accommodate real-world complexities. 

Highly focused on field results, this course will examine fracture mapping and production results from numerous fields.  Opportunities to incorporate real-data feedback into the fracture engineering process will be described.  Case studies and topics are customized to the audience; questions and discussion will be encouraged throughout the course. 

This course DOES NOT include fracture simulator training.  Participants WILL NOT have hands-on training with a fracture propagation model necessary to generate a pump schedule for specific wells.  Instead, this course is designed to help participants understand the application and limitations of existing simulators and production models, and develop an understanding of techniques to improve productivity.  Additional training focusing on fracture propagation simulation can be completed before or after this course with equal effectiveness.

Mike Vincent is a consulting engineer with more than 20 years of experience in economic optimization of hydraulic fractures. After completing his degree at the Colorado School of Mines, he worked with Amoco in Denver, and with ARCO in Anchorage, Kuparuk, and Denver. Mike started Insight Consulting in 1996, specializing in fracture design and reservoir analyses.

Mike has also provided technical support to CARBO Ceramics since 1997, allowing him to analyze frac treatments in reservoirs around the world. He has written more than 25 technical papers, has been awarded two patents, and has instructed more than 100 seminars on fluid flow, fracture design, and practical production optimization. Mike presents fracturing schools to numerous companies and organizations, and recently served as a Distinguished Lecturer and Distinguished Author for SPE.
