Assignee:

Halliburton Energy Services, Inc. - Houston TX

International Classification:

E21B 33/16

US Classification:

166291, 166294, 166295

Abstract:

A method of controlling the physical interface between two wellbore servicing fluids during the displacement of one wellbore servicing fluid by another, the method comprising selecting a liquid plug having a viscosity greater than the viscosity of the two wellbore servicing fluids, introducing a first wellbore servicing fluid into the wellbore, introducing a volume of the liquid plug into the wellbore, and introducing a second wellbore servicing fluid into the wellbore, wherein the liquid plug is selected such that the mixing between the two wellbore servicing fluids is minimized.

International Classification:

E21B 33/12

US Classification:

166386

Abstract:

A method of servicing a wellbore comprising preparing a liquid plug, allowing the liquid plug to polymerize into a highly deformable elastic plug, and placing the highly deformable elastic plug into a wellbore. A method of servicing a wellbore comprising preparing a liquid plug, allowing the liquid plug to polymerize into a highly deformable elastic plug, combining the highly deformable elastic plug with at least one conventional plug to form plug combination, and placing the plug combination into a wellbore. A method of servicing a wellbore comprising preparing a liquid plug, allowing the liquid plug to polymerize into a highly deformable elastic plug, placing the highly deformable elastic plug into a wellbore, and deforming the highly deformable elastic plug.
