Well abandonment

A paradigm shift in drilling and well construction

Globally, operators are faced with a large volume of wells, that require plug & abandonment, and they are now realizing that these wells have not been constructed to accommodate risk free, CAPEX effective P&A.

Couple this to ever stringent local regulations, operators' P&A costs have significantly increased and can range from USD 4 million for a single platform well and up to USD 12 million for a single subsea well.

This realization has driven a paradigm shift in drilling and well construction methodology, to implement best practice for later well abandonment over the duration of the well life, during design, construction, production and ultimately 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. combine cement with mechanical barriers and resins to construct wells now, planning for the future.

Foundation for P&A cement plug

To support this market shift, our WAB range, when incorporated within the cased hole for IS0 14310 V0 barrier or open hole, for IS0 14310 V3 isolation across the cap rock during well construction phase, will provide added future value as the foundation for placement of P&A cement plug, significantly reducing the future complexity and cost associated with P&A.
