Discover how Welltec’s technologies help address the critical challenge of Sustained Casing Pressure
Sustained Casing Pressure (SCP) continues to be one of the most persistent and costly well integrity challenges faced by operators globally. If left unresolved, SCP can lead to safety risks, regulatory non-compliance, and the need for expensive interventions. In this on-demand webinar, Welltec’s Global Solutions Director, Paul Hazel, shares technical insight into the root causes of SCP, supported by real-world data and case-based examples.
The session introduces advanced, field-proven solutions that enhance long-term well reliability and reduce operational uncertainty. Whether you are managing well completions, integrity, or production, this webinar offers practical knowledge to help mitigate SCP more proactively and efficiently.
To complement the discussion, a SPE technical paper on “Evolution of a Well Annular Barrier for Mitigation on SCP” (SPE-180020-MS) is linked below. This technical paper outlines the development of a novel zonal isolation packer, Welltec’s Well Annular Barrier (WAB), and highlights its capability to deliver pressure-tested sealing integrity through direct downhole measurement. The paper also explores how integrated monitoring enhances confidence in SCP barrier performance, offering operators a qualified, validated solution to this critical issue.
A novel, Well Annular Barrier (WAB) was introduced back in 2011 as an open-hole, zonal isolation packer. Its strength, ruggedness and pressure capacity over the past four years has proven it a valuable solution. Especially for ensuring the successful cementing of casing strings which were required to be run through challenging environments such as overburden, depleted zones, water bearing sands or unconsolidated zones.
Work is in progress to develop a verification system for WAB expansion and integrity, further growing its capabilities and the operating envelope in which it can be deployed. This will in turn increase the WAB’s potential applications, and use as a stand-alone, open-hole barrier.
The newly developed system consists of pressure and temperature sensors either mounted independently from, or integrated with, the WAB. Annular sealing integrity will be confirmed by direct pressure measurement down-hole.
With a career spanning 35 years and global knowledge in well integrity and lower completion well design, Paul delivers exceptional value to clients - focusing on risk mitigation and production optimization over the life of a well.
