WAB® for Well Abandonment
Future-proof wells for CAPEX effective P&A
Our WAB for Well Abandonment range, when incorporated within the cased hole as a life of well IS014310 V0* annular barrier or within the open hole, for life of well IS014310 V3 isolation, across the cap rock during well construction phase, will provide significant future value as the foundation for critical placement of P&A cement plug, significantly reducing the future complexity and CAPEX & OPEX cost associated with P&A.
A Mumbai based NOC, required a solution to provide permanent isolation of a depleted reservoir (if encountered) during the drilling phase on a 3 x well...
An IOC had an appraisal well application that required a number of solutions, to allow them to construct and complete the well to their high standards. The list...
Globally, operators are faced with a large volume of wells, that require Plug & Abandonment, and they are now realising that these wells have not been constructed to accommodate Risk Free, CAPEX effective P&A. Couple this to ever stringent local regulations, operator P&A costs have significantly increased and can range from $4Mio for a single platform well and up to $11Mio for a single sub sea well.
This realisation has driven is a paradigm shift in drilling and well 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 e.g. combine cement with mechanical barriers and resins to construct wells now, planning for the future.
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.
