Abstract
A method includes placing, via a bailer, a slurry into a wellbore to deposit a slurry downhole. The slurry includes a solids mixture and a fluid. The method also includes terminating placement of the slurry for a period of time. A viscous pill inhibits settling of the solids mixture, and the slurry displaces the viscous pill in contact with a surface of a screen.
Claims20
A method for depositing a solids slurry in a wellbore, the method comprising:
- depositing a high viscosity fluid at a target location in the wellbore to form a viscous pill;
- and
- depositing, via a bailer, a slurry at the viscous pill, wherein depositing the slurry at the viscous pill displaces the viscous pill from the target location.
A gravel filter installation system, comprising:
- a screen;
- a viscous pill deposited at the screen;
- a solids slurry;
- and
- a bailer configured to deposit the solids slurry at the viscous pill such that the solids slurry displaces the viscous pill.
