Session I: Foundation: Scope and Frame Up Session Manager: Don Whitfill, Halliburton Depending on the root cause, there are several different engineering approaches that may be taken for the prevention and treatment of lost circulation. The key to determining the approach required is an understanding of the root cause and possible mechanisms of both the loss and the treatment. A common language with common understanding of these terms and mechanisms from both the rock mechanics and drilling fluids perspective is imperative to enable effective discussion throughout the Forum. This session will identify and discuss these basic principles to set the stage for more in-depth discussion in the remaining sessions. |
1300-1630 |
Session II: Foundation: Maintain Borehole Stress Session Manager: Mohammed Azeemuddin, Chevron This session will discuss how to maintain borehole stress in cases where borehole irregularities cause losses. It will cover:

Session III: Foundation: Create Borehole Stress Session Manager: Dave Clark, Baker Hughes This session will focus on how to create or build borehole stress beyond what naturally exists. Discrete stress building treatments and continuous stress building treatments theories, as well as water-based mud (WBM) and non-aqueous fluid (NAF) will be discussed. This session is key to this forum and appears at its beginning so discussion threads can continue throughout the forum. |
1830-2200 |
Session IV: Diagnostics Session Manager: Fred Dupriest, ExxonMobil Diagnostic practices are used in the field to determine the specific loss mechanism and to ensure the treatment with the greatest likelihood of success is selected. These practices and field practices for measuring the wellbore integrity directly and logging techniques to identify in-situ or induced fractures and estimate the stress field indirectly will be discussed in this session. |

Session V: Vugs, Natural Fractures, and Other Formations Session Manager: Weldon Nance, Hess This session will showcase the discussion of case histories of losses and treatments in the environment of naturally-conductive fractures and vugular formations. Current operator practices as well as new technology either from operators or service companies will be considered. Impacts of pressured formations open in the same wellbore section will be reviewed. The session will be used to identify gaps that new or unconventional solutions could bridge. |
1830-2200 |
Session VI: Laboratory Methods for Assessing Fracture Sealing and Loss Circulation Control Session Manager: Jim Friedheim, MiSWACO This session will be dedicated to reviewing the current lab methods for assessing fracture sealing, controlling downhole losses, and evaluating wellbore strengthening as they relate to field applications. The focus of the ensuing discussion will be directed to determining what areas of loss circulation we simulate well and the areas where we need improvement. Where does this expertise in testing need to reside: operators, service companies, or universities? Ideas for improved or new facilities will be proposed. |

Session VII: Field Application Needs Session Manager: Gary Young, OXY Oil and Gas This session is designed to encourage discussions on lost circulation material (LCM) and wellbore strengthening field applications. These applications involve optimum placement procedures that include remote monitoring and particle size distribution measurements. Downhole placement equipment and surface recovery and mixing equipment requirements will be discussed. |
1300-1630 |
Session VIII: Session Issues/Topics Session Manager: Fersheed Mody, Apache Corporation This session is dedicated to elaborate on the innovative ideas that have been raised by the participants during the earlier sessions. They will strive to build on these ideas incorporating a multi-discipline mindset. The session could incorporate a discussion of out-of-the-box ideas not uncovered in the earlier sessions. |
