Organic acid precursor
Slowly release organic acid to minimize losses and achieve uniform filtercake removal.
Breaker surfactant package
PEN-X breaker surfactant package enhances penetration of nonaqueous filtercakes by destabilizing the emulsion around the calcium carbonate or barite particle. Usable by itself in a brine to help disperse a barite-laden oil-based filtercake or it can be added to a VERSA-OUT water-based filtercake breaker system to enhance the cleanup of a calcium carbonate by water wetting the filtercake. PEN-X package can also be added to the FAZE-OUT reversible-system water-based filtercake breaker for improved dispersion and water wetting.
PEN-X package is used when bottomhole temperature is below 250 degF [121 degC],† when a faster reaction is desired, or for more tenacious filtercakes.
Typically used in combination with D-STRUCTOR breaker or a VERSA-OUT breaker system to dissolve the soluble material in the oil- or synthetic-based filtercake, leading to full filtercake dissolution over an extended time and depending on the bottomhole temperature.
If the oil- or synthetic-based filtercake is barite laden, PEN-X package can be used to help pull the oil from the barite particle and help disperse the filtercake.
Recommended usage is 5 to 20% by volume. Use with the D-STRUCTOR breaker. PEN-X package is compatible with seawater, potassium chloride, sodium chloride, calcium chloride, sodium bromide, calcium bromide, sodium formate, and potassium formate.
Bioassay information is available upon request. Handle as an industrial chemical, wearing protective equipment and observing the precautions as described in the material safety datasheet (MSDS).
Packaged in 55-galUS drums or cubic-meter totes and is available from all M-I SWACO plant and warehouse locations.
Store in a dry location away from heat or ignition sources, and minimize dust.
