Well Integrity Challenges From Casing Failures During Fracturing
Ticketed Event
Instructor(s) George E. King

Downhole casing damage is being increasingly recognized as a challenge to well integrity in the active or child well (the well being fractured) and is a distinctly different than the fracture driven incidents that have an impact on passive wells (typically offset wells). This one-day training course will examine the potential causes and possible prevention actions that may be taken during well drilling and completions steps.

Session 1: Selection Process for Refracturing Candidates
Session Chairpersons Dick Leonard, ProTechnics; Luis Castro, Baker Hughes, a GE Company; Matt White, ConocoPhillips; Sheldon Moos, Devon
Speaker(s) Massiel Puentes, Encana; Tarik Abdelfattah, Baker Hughes, a GE Company; Scott Lapierre, Shale Specialists LLC

A rigorous screening process can greatly improve the odds of success. This session will provide insight on how to choose the best refracturing candidates. Presentations will provide attendees with an awareness of the intricacies necessary for well selection required for successful refrac campaigns.

10:10 - 10:30
10:30 - 12:00
Session 2: Intra- and Inter-well Fracture-driven Interactions Between Horizontal Wells
Session Chairpersons Ali Daneshy, Daneshy Consultants; George King; Consultant; Sam French, BP
Speaker(s) Pete Bommer, Abraxas Petroleum Corporation; Lionel Ribeiro, Equinor; Steven Altman, Brown & Borelli, Inc

There is abundant field data pointing to communication between hydraulic fractures created in the same or in adjacent horizontal wells. Important consequences of these interactions include uneven production distribution between fractures in the same well, and, production interference between adjacent wells. Understanding the nature, cause and effect of these interactions is critical for optimizing various production operations, including re-fracturing. This session will discuss the different types of intra- and inter-well communications, their causes, how to identify them, and attempts to reduce their negative effects.

12:00 - 13:30
13:30 - 15:00
Session 3: Completions and Coiled Tubing Intervention
Session Chairpersons David Traugott, National Oilwell Varco; Michael McKown, NCS Multistage LLC; Sam Schroeder, ConocoPhillips
Speaker(s) Juan Vargas, ConocoPhillips; Bob Barba, Enventure GT; Amrut Athavale, Oxy

This session will focus on completion and coiled tubing technologies that are directly involved in refrac applications.  These technologies include but are not limited to: (1) new or improved completion hardware such as, expandable and cemented liners, packers, plugs, sliding sleeves, dissolvables, etc.; (2) innovative implementation of completion and/or coiled tubing systems; (3) new design methodology or tools; (4) case histories, including design and execution of best practices, operations efficiencies and economic considerations.

15:00 - 15:30
15:30 - 17:00
Session 4: Diversion and Zonal Isolation
Session Chairpersons Blake Horton, Encana; Dario Stemberger, Concho; Sam French, BP
Speaker(s) Mary Van Domelen, Well Data Labs; Amit Sharma, Schlumberger; Jamie McEwen, ConocoPhillips

The session will explore diversion and zonal isolation options to assure re-fracture treatments are placed in the targeted locations for optimum results. These techniques have historically included chemical, ball diversion and other solid diversion materials. The session will explore the results of these applications having been deployed. Additionally, new materials and techniques to improve diversion and zonal isolation will be discussed.

17:00 - 18:30
Networking Reception and Poster Session

The Poster Session will be held in conjunction with the Reception on Tuesday evening. The Poster Session will have topics that cover all aspects of technologies and case histories relevant to ReFracturing. The poster owners will be present during the poster session to explain and answer questions about the topics on their posters. We encourage all attendees to interact with each other during the reception, and rotate through the posters with questions and requests.

Interested in presenting a poster?

Session 5: Refrac Design and Economic Modeling
Session Chairpersons Brian Ward, Marathon Oil; Dario Stemberger, Concho; Matt White, ConocoPhilips; Sheldon Moos, Devon
Speaker(s) Roland Cadotte, Halliburton; Dr. Mukul Sharma, University of Texas; Tuba Firincioglu, Nitec

Designing a refrac job requires an operator to have a holistic view of the geomechanics of the reservoir, historical production profiles of the candidate and neighboring wells, initial completion designs, and many other factors prior to pumping the actual field trial. To have a successful design, operators rely on simulation and economic modeling completed prior to the test to assess the risk versus the reward. This session will focus on the types of modeling that give insights for designing a refrac job and add confidence to delivering a positive rate of return project. 

10:00 - 11:30
Session 6: Diagnostics and Surveillance
Session Chairpersons Ali Daneshy, Daneshy Consultants; Blake Horton, Encana; Dick Leonard, ProTechnics; Robert Coon, PetroFrac Oil Tools
Speaker(s) Stephen Robinson, DarkVision; Chad Senters, Core Lab; Jessica Iriarte, Well Data Labs

Common concerns that arise around horizontal well refracturing are often centered around stimulation effectiveness and analyzing the end result: How much lateral length coverage can be achieved? Do the isolation methods work? Has new rock been contacted?  Pairing the proper diagnostic tools with refracturing opportunities can help the industry better address these concerns.  This session will present effective diagnostics solutions and refrac case histories that help enable the sub-surface insight needed to optimize horizontal fracturing.

11:30 - 13:00
13:00 - 14:30
Session 7: Future and Emerging Technologies
Session Chairpersons David Traugott, National Oilwell Varco; Jason Baihly, Schlumberger; Sam Schroeder, ConocoPhillips
Speaker(s) Brad Holms, Comitt Completion Tools; Sam Young, Deep Imaging; Francis Neill, Ziebel

Refracturing technologies continue to evolve over time as more wells are restimulated and operators observe results.  This session will focus on new technologies pushing the envelope in well restimulation.  Furthermore it will focus on new refracturing treatment methodologies being trialed based upon gaps in current refracturing processes.  Lastly, this session will look at various diagnostics being applied to capture more information before, during, and after refracturing treatments in order to push the industry further up the learning curve.  

14:30 - 15:00
15:00 - 16:30
Session 8: If I Could Do It All Over Again
Session Chairpersons Matt White, ConocoPhillips; Mojtaba Shahri, Apache Corporation; Robert Coon, PetroFrac Oil Tools
Speaker(s) Josh Inscore, Devon; Michael Kraynek, Crestone Peak

Many different types of refracturing have been completed: some successful and some not.  This session will focus on lessons learned and to discuss what should be done going forward.  This session should help keep others from making the same mistakes that others have made, and to learn to progress the technologies and practices to further refracturing technologies and procedures.
