differs from other types of lost circulation materials, in that it
rapidly forms a solid plug within the loss zone, rather than remaining
at or near the face of the well bore. This minimizes the
possibility of the seal being removed during drilling operations,
thereby necessitating repeated remedial treatments of the same
zone. Solving the loss problems as soon as possible after it
occurs prevents excessive mud volume from entering the formation,
further propagating the fractures and compounding the loss problem.
Del Squeeze is a high fluid loss, high solids slurry, and its performance is unique compared
other types of LCM. When placed in and/or across a loss zone, the
liquid phase is squeezed from the slurry, leaving a solid plug behind.
There are two key factors to obtaining a successful Del Squeeze:
First, a slurry with an extremely high solids content and high fluid loss must be prepared.
Second, the slurry must be placed at the proper location in the well bore.

decreased by 0.6 sacks per barrel.
|*Due to variations in oil or synthetic & barite, pilot tests should be made to determine exact formulations. If slurry becomes too thick, add up to 1 lb./bbl. wetting agent to thin.|
