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.
