Production Analysis in Resource Plays

Reservoir Descriptions and Dynamics


Methods to assess and compare the performance of resource play multi-stage vertical and horizontal oil and gas wells will be the focus of this 2-day course. The course will use the Reciprocal Productivity Index Method® as the interpretive framework and examine flowback and longer-term production histories provided both by the instructor and participants.

Upon completion of this course, attendees can expect to be able to identify and evaluate:

  • Reservoir quality (transmissibility)
  • Stimulation effectiveness (Effective or apparent fracture length)
  • Flow geometry (radial, linear, transitions, bounded)
  • Quantify degree of anisotropy
  • Damage mechanisms
  • Time-related changes in the above

Topics include:

  • Technical basis for the RPI® methodology
    • Comparison to numerical simulation
    • The graphical presentation
    • Production signatures in the RPI® setting
    • Anisotropy and Linear systems
  • Performance comparison methods
    • Evaluation of well performance
      • Simple radial flow, stimulated well signatures
      • Early-time Flowback assessment
      • Damage event assessment
      • Anisotropic examples
      • Horizontal well examples
      • Natural fracture signatures
    • Performance comparison tools
      • Data set adequacy
      • Data set comparisons
    • Participant-provided data set evaluations

Why Attend?

This course will provide the participants with an investigative framework to engage the causative issues for maximizing well performance, subject to established goals and expectations.

Who Should Attend

Engineers and geologists who desire to find additional tools to understand well and reservoir system behavior and ways to mitigate and manage those behaviors.

James W. Crafton formed Performance Sciences in 1991, a consulting business focusing on analysis of production data to assess well operating problems. Prior to that he received the Outstanding Faculty Award at the Colorado School of Mines, where he taught for over ten years. He was awarded the Honorary Professional Degree from the University of Missouri, Rolla for his contributions to petroleum production engineering. He has received the Matson Award for technology development in water drive reservoir management. Most recently he has been recognized as a Society of Petroleum Engineers Distinguished Member. He also received the SPE Production and Completions Engineering Award for his work in hydraulic fracturing technology. In another arena, he was granted the unusual privilege of naming rights for the discovery of a previously unknown geologic formation. He has chaired the SPE Distinguished Lecture Program by SPE Board appointment, for two years. He holds several US and international patents, including letters of commendation from the US Patent Office for those patents.

Crafton graduated from Missouri School of Mines in mining engineering, petroleum option. He received his MS in petroleum engineering from the University of Oklahoma and his PhD from the University of Tulsa.
