Well shut in due to sustained casing pressure (SCP) or the development of future casing vent flow when the cement in the annulus ultimately degrades, causing the development of micro-annuli, can have immediate effects on production. Safety regulators require the elimination of SCP and wel-lok™ TDAP provides a simple, fast and cost-effective solution. These issues traditionally require multiple expensive interventions and have the potential to weaken the casing string and well as restrict your ID.
With considerable cost savings, wel-lok™ TDAP can be activated during the production phase, to prevent shut in due to SCP and can also be activated during abandonment to avoid multiple perf & squeeze attempts or section milling. Preinstalled during completion the TDAP can be activated either immediately or at a later date using a simple wel-lok™ chemical reaction heater.
Installed as part of the original case string, the Thermally Deformable Annular Packer (TDAP) can be used immediately as a primary barrier to seal the annulus or if your workflow demands it, a secondary insurance policy for the likely future failure of primary cement or resin.
