Swell type packers were not considered a viable solution due to ∆p requirements and the associated down time for swell along with the poor life of well characteristics of the swell type material. Furthermore, ECP type solutions were not considered as they require to be set with cement to safeguard against the thermal fluctuations within the application.
RIH with 812WAB on toe valve + float shoe – ran on drill-pipe coupled to a hydraulic release running tool. TD – p/up to neutral and apply hydraulic pressure down DP to set WAB above / across the fault drop ball and then apply release pressure liner running tool.
The set 812WAB then became the sump of the well, permanently isolating the fault and facilitating the completion of a GP lower completion above.
812WAB fault isolation solution allowed client to realize 50% CAPEX reductions, when compared with previous LCM mitigation methods, along with risk reduction for the subsequent gravel pack completion, resulting in complete pack placement.
Isolation of total losses allowed for deployment of single zone gravel pack completion.
WAB open hole isolation plug, enables CAPEX effective and reduced risk gravel pack completion via isolation of total losses.
Our WAB® for Well Abandonment range, when incorporated within a cased or open hole across the cap rock will provide significant future value as the foundation for critical placement of P&A cement plug.
