• RIGFOAM-3 may be used in coil tubing operations to remove sand or other solids which have created a flow restriction or plugging. RIGFOAM-3 is an excellent choice for gravel pack removal. Extensive field tests have proven that RIGFOAM-3 keeps the hole clean and free of cuttings while maintaining low standpipe pressure.
• As a flow enhancer for low pressured wells, RIGFOAM-3 is used as a foaming agent to lighten the fluid column, thereby assisting in lifting and encouraging flow.

Typical concentrations of RIGFOAM-3 range from 0.1% to 0.5%, depending on the formation and injection fluid, injection rates, compressor equipment, etc. Usually 10 to 20 gallons of RIGFOAM-3 are batched down the tubing, followed by two barrels of produced water as a flush. Formation gas perking through the liquid generates foam throughout the column and assists many weak wells in overcoming hydrostatic pressure. For fresh water, KCl and NaCl brines, the typical concentration of RIGFOAM-3 is 2 to 6 gallons per 10 bbl fluid. Please consult a RIG-CHEM representative for a specific RIGFOAM-3 application recommendation.
