WELLTEC AND CLIENT COLLABORATIONUpgraded qualification enables flexible deployment
Conventional solutions considered would result in increasing cement volume:
Under reaming to 7 1/8” = extra rig time.
Shoe track extended = breakthrough into the oil / water contact.
Within this challenging application, zonal isolation was critical to optimizing acid stimulation pre-flush.
WAB installed and expanded on a single trip with liner hanger.
WAB for slim hole cement assurance prevents water production.
Through its versatility in application and robustness in design, the WAB® (Welltec® Annular Barrier) for well completions can be utilized to provide solutions, to many requirements throughout the completion phase of a well.
