It is used in conjunction with an encapsulating polymer (PHPA) and brine phase KCL. It can meet various drilling challenges, ideal for use in high-angle drilling, and deep and sub-salt applications.
Glycol HC is a high cloud point glycol designed for a salinity range. It can provide significant reductions in mud dilution rates, reduced friction coefficients, fewer mud-related drilling problems, and enhanced rates of penetration. It is particularly effective with common salts used in drilling fluids.
Glycol HC is compatible with most aqueous systems.
When clouded out the glycol at the surface of the troublesome Swelling shales forming a water-repellent barrier, thus minimizing the effects of troublesome water-sensitive shales on the drilling process and mud properties.
Excellent inhibition is observed in the presence of potassium ions which are recommended for optimum performance.
Glycol HC has application in poly-glycol systems in fresh to medium or high salinity make-up water and can be used in wells with moderate formation of temperature. When used properly, this medium cloud point additive helps to stabilize troublesome shales by plugging shale pores, preventing the equalization of hydrostatic pressure away from the wellbore.
Glycol HC store in a dry, well-ventilated area. Keep the container closed. Keep away from heat, sparks, and flames. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, Shrink-wrapping, and/or stacking.
Glycol HC is packaged in 200 kg net weight. polyethylene or steel drum.
Glycol HC shelf life of at least one year from the date of manufacture when stored in the original sealed containers in a cool and dry place.
Glycol HC must be handled as an industrial chemical, wearing protective equipment and observing the precautions as mentioned in the MSDS.
Cloud Point: The temperature at which a solution of a surfactant or glycol starts to form micelles (molecular ag- glomerates), thus becoming cloudy. This behavior is characteristic of nonionic surfactants, which are often soluble at low temperatures but “cloud out “at some point as the temperature is raised. Glycols demonstrating this behavior are known as “cloud-point glycols” and are used as shale inhibitors. The cloud point is affected by salinity, being generally lower in more saline fluids. The purported mechanism is that the glycol clouds out at higher downhole temperatures, coating the surface of clays and preventing hydration. Cloud point glycol exhibits clouding behavior when used in salt solutions. Clouding behavior results from changes in water or brine solubility of the glycol with temperature. Cloud formation is dependent upon salt concentration and the concentration of the glycol itself, as well as temperature and pressure. The cloud point glycol series covers a range of low, medium, and high cloud point temperatures suitable for brine salines of seawater, from the most common 15 percent NaCl-based fluids to saturated salts.
Glycol HC is a water-soluble high cloud point glycol of lox toxicity and a multifunctional additive for drilling fluids. It is used in water-based drilling fluids to improve lubricity and shale stability and extend the temperature stability. It can meet various drilling challenges and is ideal for use in high-angle drilling, extended rich drilling, and deep and sub-salt applications.
Glycol HC is a low toxic. Versatile, high cloud point additive designed for medium to high salinity water level systems and can be used in wells with moderate formation temperature. It can provide improved wellbore stability, lubricity, high-temperature filtration control, and reduce dilution rates and bit balling
This shale inhibitor intercalates and reduces the space between clay platelets so that water molecules will not penetrate and cause swelling the Manufactures the full range of cloud point glycols used as high-performance shale stabilizers for drilling applications.
Glycol HC is zero foam.
