Session Managers: Carol Mann and Simon McCulloh
Managing wellbore position survey data is a critical activity with significant consequences if mishandled. As the process for managing survey data has evolved greatly over the past 30 years, directional survey database specialists will present current best practices. A panel session will follow for participants to gain the maximum understanding. Topics covered will include:
Session Managers: Steve Mullin and Harry Wilson
This session will be based on work carried out by the Collision Avoidance Work Group of the SPE Wellbore Positioning Technical Section. The group recently produced a document titled “The Fundamentals of Successful Well Collision Avoidance Management.” This document will be presented and the eight elements of successful collision avoidance will be discussed. Two of the elements will be presented in detail, survey programme design and collision avoidance procedures. These presentations will be followed by an operator representative who will describe the system used by his company to manage all eight elements. The session will close with a panel discussion with questions and answers.
Session Managers: William Allen and Benny Poedjono
In this session, visualisation tools will be presented along with the importance of a robust process management system for safety, consistency in performance, and workable contingencies. Drilling challenges will be highlighted, specifically well position versus well requirements. The session content begins at the point after the transfer of the drilling programme to the directional driller. How drilling constraints, execution methods, and tools are combined to drill the well safely and efficiently will be reviewed. Focus will be on the importance of effective communication and execution performance. Participants will gain familiarity with various tools that enable successful well placement.
Session Managers: Steve Grindod and Angus Jamieson
Although every relief well is unique, this session gives an overview of issues that should be considered when planning and executing a relief well. Participants will be able to experience some of the problems in a “relief well challenge” by using a drilling simulator to drill a relief well to the first ranging point followed by a ranging and steering exercise as the interception point is approached. Delegates will be required to use their laptops during this session.
Session Managers: Ben Hawkinson and Robert Wylie
Commercially available techniques for intercepting wellbores will be presented, along with their applications. These techniques include passive ranging systems, as well as active ranging systems that might involve current injection or deployment of rotating magnets.
Interception applications include well intersections such as relief wells, coal bed methane drilling, wellbore re-entries for remediation, enhanced production, or plug-and-abandon operations, as well as applications where it is desired to maintain separation over a distance, such as steam-assisted gravity drainage (SAGD) well twinning.
Participants will gain practical knowledge by working in small groups to choose techniques applicable to different case studies.
