SCP

Pressure in an annulus that

  1. rebuilds after having been bled down;
  2. is not caused solely by temperature fluctuations; and
  3. is not a pressure that has been imposed by the well operator
  • Note: 1 to entry: Sustained casing pressure can be present on wells without annular access.

Sustained casing pressure (SCP)

Sustained casing pressure (SCP) is defined as 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.
