Description
Course Overview: This course provides a comprehensive overview of Plug and Abandonment (PnA) practices and challenges, with a particular focus on failure diagnostics and remediation strategies employed by operators based on diagnostic results. The primary emphasis is on current trends in identifying failures, restoring zonal isolation, and evaluating the efficiency of established barriers.
Participants will gain insights into modern PnA practices, guidelines, and regulations followed in the USA and globally for well decommissioning.
Agenda:
- Global and US Regulations, and Operator Guidelines for Plug and Abandonment
- Overview of NORSOK , ISO and API guidelines for well integrity and PnA.
- Common trends in barrier verification.
- Recommendations and local requirements for PnA operations.
- Current Practices and Concepts in Plug and Abandonment
- Establishing robust barriers to effectively isolate zones with flow potential.
- Strategic placement of cement plugs and mechanical barriers.
- Overview of verification methods to ensure barrier integrity.
- Advances in rigless and partially rigless operations to enhance operational efficiency.
- Ensuring Barrier Integrity Before and During PnA
- Enhancing diagnostics with acoustic testing methods, including spectral acoustics and the development of noise logging for PnA applications.
- Overview of remediation techniques commonly used to restore isolation, including unconventional approaches.
- Verification and testing of newly established barriers to ensure their effectiveness.
This course equips attendees with the necessary knowledge and skills to address key challenges in Plug and Abandonment operations, ensuring compliance with industry standards while enhancing operational efficiency and safety.
