Sustained casing pressure (SCP) is common in many wells globally (>30%) and present within multiple annuli. Since 2009, well integrity has cost operators over $75 billion. This has provided the impetus for the industry to focus on and rework international standards on well integrity management.
Through the incorporation of the WAB (Welltec Annular Barrier) to the well construction phase, Welltec® are facilitating enhanced well integrity via standalone cased hole barriers, open hole isolation and cement assurance.
At Welltec, we design and test our WAB range in accordance to IS014310, the industry standard which defines packer design validation grades.
Our V0 WAB range for cased hole SCP barrier has been tested to IS014310 V0*, the highest validation level within this industry standard, and provides, a verifiable, life of well barrier against SCP.
Our V3 WAB range for open hole isolation, has been validated to IS014310 V3*, the highest fluid validation level within this industry standard. The WAB provides life of well V3 isolation assurance within the open hole section. Additionally, it can be set within cement or used in combination with 2nd stage cement systems to support HP columns of cement to prevent SCP or production of unwanted gas or water.
