    CAPEX effective P&A & future proof construction
Future-proof wells for CAPEX effective P&A by incorporating Welltec® Metal Expandable Packers technology, and Welltec® Expandable Anchor (WEA) for Casedhole Plug.

A paradigm shift in drilling and well construction

Globally, operators are faced with a large number of wells that require plug & abandonment (P&A). By today’s standards, many of these wells are not constructed to accommodate risk free CAPEX effective P&A.    

The need for safe and effective P&A has driven a paradigm shift in drilling and well construction methodology to implement best practice for the entire life of a well, including design, construction, production, and ultimately its abandonment.

Cement alone is not a reliable barrier, and operators and now planning for the installation of multiple barriers and multi-component barriers i.e., combining cement with mechanical barriers and resins to construct wells in a more proactive approach to abandonment.

Foundation for P&A cement plug

The Welltec® Expandable Anchor (WEA) for Casedhole Plug provides a temporary or permanent abandonment solution with a qualified gas-tight seal. Surface-controlled hydraulic expansion ensures bidirectional anchoring and sealing. The solution is qualified in accordance with the highest-level API and ISO standards.

The design of the WEA for Casedhole Plug minimizes subcomponents, ensuring reliability and efficiency while simplifying well construction. The WEA enables reciprocation, circulation, and/or rotation during deployment.
