Dual 1214WAB® Deliver Critical Cement Assurance in Sidetrack
WELL TYPEHydrocarbon producer
PRODUCT / PLACEMENTWithin 12 1/4" open hole
ISOLATION OF WATER BREAKTHROUGHVia dual WAB placement within open hole
WAB FULLBORE ID ENABLES SIDETRACKWithout changes to the lower completion design
WELL PRODUCTION REINSTATEDAs a direct result of dual WAB solution
As a result, the subsequent sidetrack well incorporated two 1214WAB within the 12 1/4" open hole section, in combination with cement to provide a permanent barrier to flow of scaling waters.
The primary cement operation was conducted and the dual 1214WABs were expanded within green cement against the bumped cement plug. The 1214WABs set in 12 ¼” section at 10,273 ft and 10,199 ft, effectively straddling the scaling water producing zone.
First deployment WABs through a milled out window in a sidetrack application.
Provide reliable production for the operator.
Avoid cost of drilling a new well.
Production data confirming no scaling water produced
WAB seal verified in open hole.
The WAB’s robust design, allows for deployment through a milled window to prevent scaling water flow across a thin shale.
Our ISO 14310 rated, steel expandable WAB® (Welltec Annular Barrier) is expanded between the base pipe and the casing or the borehole by applying pressure in the casing. It conforms to the actual well bore geometry.
