Medium Cloud Point Glycol (RXSOL MCPG)
Product code RXSOL-81-8199-210
Medium-Cloud-Point polyglycol for moderate-salinity fluids and high temperatures.
Description
Medium Cloud Point Glycol RXSOL MCPG is a broad cloud-point, wide molecular weight range, additive designed for medium-to-high salinity polyglycol systems. It can provide improved shale stability, lubricity, high-temperature filtration control, plus reduce dilution rates and bit balling.RXSOL MCPG is recommended for freshwater to seawater polyglycol systems. While polyglycols are most effective when used in conjunction with an inhibitive salt in non-dispersed polymer systems, they can be used as additives in most water-base systems.
Application
RXSOL MCPG has application in polyglycol systems in fresh-to-medium salinity makeup water and can be used in wells with low formation temperatures. This medium cloud-point additive helps to stabilize troublesome shales by reducing liquid phase activity and by plugging shale pores, preventing the equalization of hydrostatic pressure away from the wellbore. Polyglycol systems are generally low-to-medium density, nondispersed polymer systems utilizing an electrolyte to activate the cloud-point polyglycol. They have application where troublesome water-sensitive shales are to be drilled, and can be used in lieuof oil-base systems for certain applications. Medium Cloud Point Glycol RXSOL MCPG can be used in Thermally Activated Mud Emulsion(TAME) applications (near the cloud point) or in situations where it is insoluble (above the cloud point).
