Fluid loss pill for well completion.

To prevent fluid filtration during well completion, a fluid loss pill Plastirox is injected into the filter interval. A low-permeability filter cake forms on the inner surface. The filter cake prevents the loss of fluids into the formation, eliminates well control problems and preserves the reservoir properties for the required time.

After completing the operation, the filter cake and fluid loss pill are easily removed from the filter surface with minimal depression caused by the formation fluid. Removing the filter cake does not require any breakers (but possible, if necessary).
