DIPRO Reservoir Drill-In Fluid | Schlumberger


High-density divalent reservoir drill-in fluid

Protect the reservoir with low filtration rates and a thin filtercake

DIPRO high-density divalent reservoir drill-in fluid is the industry’s first biopolymer-free, brine-based reservoir drill-in fluid formulated for use in divalent brines and engineered to optimize production. DIPRO fluids initiate an interaction of components that produce a nonbiopolymer system with excellent suspension characteristics while maintaining extremely low, high-shear-rate viscosities.

DIPRO fluid utilizes optimal bridging particle distributions and formulations without the need of biopolymers for reservoir drill-in fluids (RDFs) in divalent brines ranging from 11.5 to 17.0 ppg—enabling customized formulations—with ultralow-permeability filtercakes that are easily removed.

DIPRO LD low-density divalent RDF extends the density down to 9.8 ppg in low-density divalent brines.
