PRODUCT DESCRIPTION
Rantec HFX provides strong rheology with high Yield Points and good annular suspension capabilities. In today’s market HFX is an economical choice as a viscosifier and provides the best possible suspension of weighting solids.
RHEOLOGY
The Rantec HFX provides excellent rheological properties as shown in the figure below. Rantec GP73™ is shown for comparison to HFX.
| HFX | 1.00 | 1.50 | 2.00 |
|---|---|---|---|
| PV | 12.00 | 13.00 | 19.00 |
| YP | 19.00 | 29.00 | 34.00 |
| n Annulus | 0.41 | 0.27 | 0.24 |
| K Annulus | 2.30 | 6.41 | 10.11 |
| Density | 11 to 20 Lb/Gal |
VISCOSITY
GP Polymers and Rantec HFX require very low doses to produce workable drilling viscosity. The amount of dry product required is low, reducing the labor of handling large volumes of material. Viscosity of GP polymers increases exponentially with dose. Small changes in polymer content may be used to increase or decrease viscosity very efficiently.
| Viscosities | |||

| 600 rpm Apparent Viscosity | |||
| Lb/BBL | 1 | 1.5 | 2 |
| GP91™ | 13 | 23.65 | 36 |
| GP82™ | 15.75 | 25.9 | 38.8 |
| GP73™ | 15.5 | 25.6 | 39.25 |
| HFX | 21.5 | 27.5 | 36 |
PACKAGING
Rantec HFX standard packaging is 25-kg multiwall paper bags stacked 40 per pallet. Other packaging options are available including plastic pails and 2000-lb totes.
SAFETY
Carefully read the SDS sheet and post according to company policy and governmental regulations. GP series polymers are inherently safe when properly handled. These products should not be ingested in significant quantities. Products become extremely slippery when wet. The product should not be allowed to become airborne as it becomes a potential explosion hazard and respiration hazard. Use proper engineering controls to prevent suspended dust.
