08:30 - 10:00
Session 1: Detailed, Global Case Histories: What, Where, When and How Much
Session Chairpersons Alberto Casero, BP; Roy Hathcock, Devon Energy; Martin Rylance, BP Russia

Casing deformation of multi-fractured horizontal wells is not a new phenomenon. However, the more recent increase in worldwide unconventional activity has demonstrated that it's occurrence and cadence is likely basin-specific. This session will attempt to frame the discussion, and demonstrate the range, variety, and severity of such occurrences, through a suite of global case histories.

Session 2: Geomechanical Causes - Role and Effects
Session Chairpersons Neal Nagel, OilField Geomechanics; Roy Hathcock, Devon Energy

A significant percentage of casing deformations appear to have an underlying geomechanics cause. During completion and early production operations from long horizontals, there is a combination of sufficient changes in in-situ stresses, pressures and perhaps mechanical properties that lead to formation failures. These failures lead to deformations of the wellbore within the lateral or build-section of the well. This session will develop and characterize these geomechanical-related causes for casing deformation during completion operations and early production.

Session 3: Well Construction, Casing, Cementing Causes - Role and Effects
Session Chairpersons Alex Crabtree, Oceaneering International, Inc.; George King, Viking Engineering

This initial well construction session will address how drilling actions, casing design, and installation, as well as cementing application during operations, can increase or decrease the potential for casing deformation. Presentations in this session will:

Identify shortfalls in static well design approaches 
Suggest linkages between types of deformation and the direct or indirect causes within the rock fabric, directional drilling problems and completions issues.

Session 4: Prediction and Monitoring - How to See It Before It Happens
Session Chairpersons Adam Aylor, ExxonMobil; Eric Davis, ConocoPhillips Global Wells; Terry Palisch, Carbo Ceramics

This session will discuss the observations that can be designed and applied to predict the possibility of deformation issues.  The session will cover means to monitor for issues that may provide early identification of a problem.  These means may include distributed acoustic (DAS), temperature (DTS), and strain (DSS) sensing, micro-seismic, stage-over-stage and annulus pressure monitoring, calipers, cameras, and operational trends.

Session 5: Management and Remediation - Fixing After-the-Fact
Session Chairpersons Alberto Casero, BP; Eric Davis, ConocoPhillips Global Wells; Martin Rylance, BP Russia

While designing without undesirable deformations is a key objective, often the deformations are first identified during the pilot or appraisal phases. In all cases, the desire is to achieve an effectively stimulated well and the associated production and data. To effectively achieve these goals, it is important that options, contingencies, and plans are available and in place to cope with and alleviate the issues.  This session will explore these options and plans.

Session 6: Discussion of Way Forward
Session Chairpersons George King, Viking Engineering; Neal Nagel, OilField Geomechanic

This final session of the summit will focus on reviewing and summarizing the previous sessions of the summit, with a goal to capture, prioritize, and offer a final review of the most significant issues and findings. In addition, an important part of the session will be to discuss potential paths forward for additional study, collaboration, or review efforts such as workshops, webinars, or panel discussions
