Keynote Presentation: Blind Testing Refrac Simulation Predictions - Results and Lessons Learned
Mark McClure, ResFrac

Chairs: Neil Modeland, Halliburton; Kevin Eichinger, BKV

Understanding a well's refrac potential is a critical exercise in evaluating well candidates, determining a valuation for an asset, and estimate reserves for a well.  This session will explore the current methods being applied in these areas by both operators and financial institutions to appropriately de-risk and determine a well's potential for refracturing.

Communication between hydraulic fractures in the same or in adjacent wells have diverse consequences such as uneven production distribution within a well and/or production interference between neighboring wells. This session showcases presentations that facilitate understanding the nature, cause and effect of these interactions as it’s critical for optimizing various production operations, including re-fracturing. Types of intra- and inter-well communications, how to identify them, and attempts to reduce their negative effects will be discussed

This session will focus on modern completion techniques and coiled tubing technologies directly involved in refrac applications. The advancement of modern completion techniques continues to expand candidate selection while reducing operational risks through lessons learned.  CT technologies are further advanced to assist in well prep, targeted treatments, and post-refrac wellbore cleanouts.
With a growing number of operators running comprehensive refrac campaigns across multiple basins, the demand for reliable and cost-effective refrac solutions is increasing as operators look to maximize value from their under-stimulated well stock.

New methods and associated technologies continue to evolve over time as operators seek to add production beyond drilling and initial well completing. This session will discuss new technologies and approaches being used and developed to improve restimulation recovery and economics and topics span from fluids and additives, downhole tools, to innovative use of legislative tax incentives.

The session aims to explore advancements made in historically proven zonal isolation techniques (cementing, ball sealers, and solid diversion materials) as well as advancing technology. Isolation of the primary completion remains a key component in driving refrac/recompletion success.

Designing a refrac job requires a holistic understanding of reservoir geomechanics, well production data, wellbore integrity, and initial completion design. Operators rely on economic modeling to appraise candidates and benchmark different designs, to determine probability of success. This session focuses on the workflow for selecting candidates, techniques, and designing effective stimulation plans for refracturing projects.

Presenters: 
Jon McKenna, Microseismic

Chairs: Dick Leonard, ProTechnics; David Traugott, Consultant

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 (including AI/Data Science solutions) and refrac case histories that help enable the sub-surface insight needed to optimize horizontal fracturing.

Many different methods of Refracturing have been utilized with some successful and some not.  This session will focus on lessons learned and a discussion of what changes could be made going forward.  This session is intended to help others learn from the mistakes and successes of others, and to learn how to progress Refracturing technologies and procedures.
