DESCRIPTION
C-Pack is a pre-mixed casing pack formulation to recover casing.
C-Pack is a non-weighted, no solids invert emulsion designed for maximum stability and lubricity.
APPLICATION
The hole should be circulated clean around the casing or rods, prior to using C-Pack as a casing lubricator. Rig the pump suction directly to an agitated drum of C-pack and pump into rods/casing as required.
Annular volumes should be calculated with an excess of 20 % allowed for over-size hole. Annular volume between PQ hole and HW casing is 1.8 litres per metre.
Displace C-Pack with mud or water leaving approximately 2 – 3 metres C-Pack inside casing. Set casing to seal and prevent flow-back.
Note: If hole is experiencing lost returns prior to running C-Pack, the C-Pack should be pumped down the outside of the casing, rotating the casing slowly, while pumping to ensure a uniform coating.
RECOMMENDED TREATMENT
One 200 L drum of C-Pack will fill approximately 110 metres of HW casing / PQ hole annulus.
