Highlights
Benefits
- High-density drill-in fluid with densities from 10.5 to 17.5 lb/gal (1.3 to 2.1 sg)
- Minimal impact on rheological profile; Sustains the fluid’s hydraulic performance
- Low-shear rate viscosity with minimal ECD
- Simple formulation compatible with divalent brines
- Filtration control up to 275ºF (135ºC) for reduced leak-off
- Biopolymer-free; easily dispersed, acid-soluble filter cake
- Environmentally preferred system components
Applications
- Reservoir drilling where divalent brine systems are required
- Open-hole completions
Overview
The Baker Hughes DYNAFLOW™ reservoir drill-in fluid is a biopolymer-free system designed for use in divalent brine applications that present challenges for conventional drill-in fluids.
The DYNAFLOW fluid increases low-shear-rate viscosity (LSRV) without significantly impacting the overall fluid viscosity profile, providing better equivalent circulating density (ECD) control and improved drilling performance.
The DYNAFLOW system is free of xanthan gum or other biopolymers, and as such, the protective filter cake produced by DYNAFLOW is easily dispersed and readily dissolved by organic acids.
