Drilling Fluids Loses – Gunk Squeeze

Drilling Fluids Loses - Gunk Squeeze

If conventional LCM pills prove ineffective, a gunk squeeze may be attempted. The method utilises the swelling property of Bentonite in the presence of water. This method is not to be used for losses in reservoir section. 

Allow four hours for the plug to set. The Bentonite will hydrate after the base oil is squeezed into the formation and it is allowed to come into contact with water from the mud.

1. Flush the cement pump and lines Thoroughly with diesel to remove all traces of water.
