This process involves placing barriers, known as plugs, at specific depths within the wellbore.

GLOBAL ETC work closely with you to ensure that your abandonment plans meet all technical and regulatory requirements. On location, our experienced, well-trained personnel execute each job with a focus on safety and quality. engineering assessments.

Changes in technology and regulatory regimes now require operators to follow stricter Plug and Abandonment (P&A) programs which ensure well integrity after abandonment. The permanent well barriers installed as part of the P&A program must extend across the full cross-section of the well such that no fluid or flow is possible through the wellbore. This requires establishing barriers in all annuli, which can be time-consuming and costly.

Re-entering wells for plug and abandonment requires an understanding of the remaining capacity of the well barrier elements: Incomplete well information, well barrier elements degradation and changes in design approach from installation to present day make this challenging.

With extensive practical and hands-on installation knowledge and experience in well decommissioning, including project definition, scope and objectives, environmental objectives, contracting and procurement strategies, logistics and detailed well abandonment procedures, organization and human resource plans, and QA and HSE plans.

GLOBAL ETC can also offer a range of complementary capabilities within the Group, including casing cutting and retrieval tools, marine procedure management, lifting and retrieval services, and facilitation of multi-operator abandonment programmes.
