Reducing or eliminating SAP (Sustained Annular Pressure)

02 October 2015

We've received this request from a group who would prefer to remain anonymous.

The Operator has wells with Sustained Annular Pressure (SAP) on the "B" annulus on newly drilled and producing wells.

Does anybody in the SPREAD community have experience in reducing or eliminating the B pressure by conducting a Lube and Bleed operation on the B annulus with:

1 - Water

2 - Viscous fluid

3 - Kill Weight Brine

Last resort is a perforate and squeeze operation.

Any feedback would be appreciated. Results can be shared.

Thanks

Dave
