Enhances the cleanup or dispersion of oil or synthetic-based filtercakes
PEN-X™ breaker surfactant package enhances penetration of nonaqueous filtercakes by destabilizing the emulsion around the calcium carbonate or barite particle. It is 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. Provides thorough and uniform destruction of FAZEPRO™ reversible invert-emulsion reservoir drill-in fluid system or VERSAPRO™ invert-emulsion reservoir drill-in fluid system filtercakes when used with the D-STRUCTOR™ organic-acid precursor breaker.
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
This package is 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.
Slowly release organic acid to minimize losses and achieve uniform filtercake removal. View
