THIXATROL^® DW 100

THIXATROL DW 100 is a unique proprietary organic polymer that has an OECD306 biodegradability of 43% and PARCOM classification of D. THIXATROL DW 100 generates an efficient rheological profile in synthetic based invert emulsion drilling fluids while having a minimal viscosity increase when subjected to reduced temperatures. This highly desirable flat rheological property is stable through 350ºF and can be extended to applications beyond deep water drilling.

THIXATROL DW 100 has a greater impact on increasing LSRR as compared to HSRR. This low shear rate rheology enhancement decreases the ratio of PV:YP to maximize hole cleaning and ROPs.

The combination of maintaining a consistent or flat rheological profile from 40ºF through 350ºF, coupled with being biodegradable and not toxic to marine life, allows for the global application of THIXATROL DW 100.

THIXATROL DW 100 exhibits an excellent balance of dispersibility for initial viscosity build, efficiency for cost effectiveness and tolerance to adverse conditions for reduced depletion rates. Control of ECD is significantly improved as compared to drilling fluids incorporating only conventional rheological additives. 

Key properties

• “Flat” rheological profile from 40ºF through 350ºF for reduced low temperature viscosity build and improved ECD control for the elimination or reduction of mud losses. 35% reduction of 40ºF HSRR
• Stable to bottom hole temperatures in excess of 350ºF
• Reduction in HSRR for a given LSRR or a reduced PV:YP ratio.
• PARCOM (Class D) / OECD 306 Biodegradation (43%) compliant for global offshore applications
• Maintains HTHP fluid loss control above and below use limits.
• Shear thinning rheological profile for improved ROP
• Compatible with conventional invert emulsion drilling fluid additives and contaminants
• Builds viscosity in clay free systems or with organoclays
• Efficient hole cleaning and suspension properties for sag control
