OPERATIONAL FOCUS ENSUREDAll objectives met in this challenging application
As no losses were encountered. The WAB was installed to support the formation from shale collapse. The lower completion consisted of a 812WAB mounted on 4-1/2’’ base pipe was made up and x-over to the 7 in liner. The WAB & liner hanger was set simultaneously against the 3-1/2’’ pre-installed HPHT bridge plug.
Due to well changes during drilling i.e. no losses, the setting of the WAB was constantly changing. This was of substantial benefit to the client, due to the versatility of the WAB and being able to set in open hole or cased hole.
The WAB’s application versatility, allows for adaptive changes in well design during milestone exploration well.
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.
