Divalent brine system secondary viscosifier
Enhances low-shear-rate viscosity.
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.
Generate elevated LSRV without the need for additional viscosifiers.
A customized DIPRO high-density divalent reservoir drill-in fluid and a zinc-bromide-brine-based filtercake breaker featuring D-STRUCTOR HD organic acid precursor were designed to clean up the RDF filtercake.
