The FORM-A-SQUEEZE high-solids slurry is a cost-effective solution to lost circulation in all types of fractures, vugular formations, matrix, and underground blowout events. When placed in and/or across a loss zone, the liquid phase squeezes from the slurry, rapidly leaving a solid plug behind. This process can cure losses instantly, without time or temperature dependency.
The recommended concentration of FORM-A-SQUEEZE slurry is 80 lbm/bbl [228 kg/m³] in either water-, oil-, or synthetic-based fluids. The slurry can be weighted to the desired density with barite or calcium carbonate.
The slurry should be pumped to the annulus, covering at least 50% in excess of the loss zone. The drillstring is then pulled slowly 90 ft [27 m] above the pill. The slurry should be gently squeezed in the range of 100–300 psi [6.9–20.7 bar] to the maximum of the anticipated mud weight required for the interval, holding the pressure for 10 to 20 min.
The FORM-A-SQUEEZE slurry lost-circulation (LC) plug can be used to stop losses occurring in any water-based and nonaqueous-base fluid and can be easily mixed in freshwater, seawater, or oil- or synthetic-based fluids. It was designed to be used as:
Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions described in the safety data sheet (SDS).
The FORM-A-SQUEEZE slurry is packaged in standard 40-lbm [18.18-kg] sacks. Store in a dry, well-ventilated area away from sources of heat or ignition. Avoid generating dust. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping, and stacking.
