Sustained Casing Pressure (SCP) is excessive casing pressure in wells that persistently rebuilds after bleed-down. It is defined as a pressure in any well annulus that is measurable at the wellhead and rebuilds when bled down, not caused solely by temperature fluctuations or imposed by the operator. SCP is caused by gas migration from a high-pressured subsurface formation through the leaking cement sheath in one of the well’s casing annuli.
At Welltec®, we design and test our WAB® (Welltec® Annular Barrier) range in accordance to IS0 14310, the industry standard which defines packer design validation grades.
Our V0* WAB range for cased hole SCP barrier has been tested to IS01410 V0*, the highest validation level within this industry standard, and provides, a verifiable, life of well barrier against SCP (Sustained Casing Pressure).
An IOC, had an appraisal well application, in the Norwegian Barents Sea, that required a number of solutions, to allow them to construct and complete the well to their high standards.
The steel packer expandable sleeve is expanded between the casing and the borehole by applying pressure in the casing. It conforms to the actual wellbore shape. Primary sealing with the borehole is achieved through a patented series of V3 rated elastomer seals, optimized along the length of the steel sleeve, backed up by a series of metal fins that provide metal to rock contact, and high strength anchoring capability.
Backed by 25 years of innovation, Welltec’s comprehensive WAB® Solutions Portfolio of tools and services enhances well construction through its entire lifecycle—reducing CAPEX and negating SCP, and increasing NPV—all from a single provider. From early planning and construction to zonal isolation and completion, Welltec is your one-stop-shop.

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.
The programmable Welltec Data Monitoring (WDM) solution measures and records pressure and temperature (data) within the liner or casing annulus onto which it is mounted.
The WLP (Welltec Light Packer) is our tiered offering to the zonal isolation and well construction & Integrity markets, developed specifically for less hazardous environment’s & lower tertiary markets.
The Welltec Isolation Valve (WIV) design, when incorporated to lower completions or liners, enables circulation & wash down or annulus fluid displacement during deployment and provides bi-directional sealing.
