DRIL-CPG-HC High Cloud Point Glycol

PRODUCT DESCRIPTION

DRILCPG-HC is a high-cloud-point poly glycol designed for high salinity poly glycol systems. It is used to stabilize hydratable and dispersible shale and enhance the lubricating and HT fluid loss control properties of water base drilling fluids. It provides improved wellbore stability and reduces dilution rates and bit balling. DRILCPG-HC is compatible for most applications specifying low toxicity additives and it is environment friendly.

APPLICATION

DRILCPG-HC stabilizes shale by adsorbing onto clay surfaces and preventing the water from entering the clay matrix. Improves the performance of PHPA based mud drilling fluids. It can meet various drilling challenges, ideal for use in high angle drilling, extended rich drilling, deep and sub salt applications.

ADVANTAGES

• Stabilizes reactive formations and helps to increase mud lubricity.

• Improves wellbore stability and shale inhibition, Reduces bit-balling tendencies.

• Improves lubricity and improves high-temperature filtration control

• Reduced dilution rates and mud consumption

• Low toxicity, stable and readily biodegradable

RECOMMENDED TREATMENT

DRILCPG-HC may be used in conjunction with most other common water-based drilling fluid products. Normal dosage ranges from 2 to 5% by volume of the liquid phase or 7 to 17.5 lb/bbl (20 to 50 kg/m3 ). After the initial treatment, periodic treatments should be made to maintain the desired concentration.
