Product Description
Surface active reagents were generally used in aqueous-based stimulation fluids to lower the interfacial tension that restricts fluid flow in the rock matrix. JKN-ZP-1 surfactant lowers the capillary pressure by both improving the wettability of the pore throat and reducing the interfacial tension. Both laboratory testing and field results have shown that JKN-ZP-1 can provide superior cleanup due to the wetting properties and surface tension reduction that lead to lower capillary pressures. The use of JKN-ZP-1 results in less swabbing time, faster cleanup, and more complete recovery of the stimulation fluids.
Technical & Engineering Information
JKN-ZP-1 promotes the cleanup of the fluid from the rock matrix because the contact angles resulting from the use of JKN-ZP-1 are higher than those for other conventional cleanup surfactants. In addition, the surface and interfacial tension values from the use of JKN-ZP-1 are also lower than most conventional surfactants used. This leads to significantly lower capillary pressures which reduces the force required to initiate flow of the stimulation fluid and therefore, JKN-ZP-1 should provide better and quicker fluid recovery following a stimulation treatment.
JKN-ZP-1 is compatible with most additives used in most matrix stimulation and acid fracturing fluids. Lab testing indicates that JKN-ZP-1 can be used for temperature applications up to 350℉ (177℃). JKN-ZP-1 can reduce the surface tension to as low as 19 Dynes/cm.
