Diverting Agent:
We manufacture a few types of Diverting Agents for Hydraulic Fracturing. PLA based diverting agent is commonly used for higher temperatures. Other diverting agents are based on Phthalic acid, EDTA. BPA etc. It can be broadly classed as Low Temperature and High Temperature Diverting Agent.
DA 355 HT, High Temperature Diverting Agent
Diverting agent DA-355 provides temporary diversion to ensure complete stimulation of all perforation clusters and targeted zones. DA-355 diverting agent is effective in high-temperature hydraulic fracturing and re-fracturing, acid fracturing and matrix acidizing applications, and provides both near-wellbore and far-field diversion in sandstone and carbonate formations. For simplified application and logistics, DA-355 can be pumped in variety of carrier fluids such as slick water, gelled acid, linear gels and viscoelastic surfactants.
DA-355 provides enhanced near-wellbore diversion in both cased-hole and open-hole applications using tri-model particle size distribution. DA-355, is comprised of a mixture of large robust particles as well as smaller particles, is designed to bridge across perforations, wormholes, and fractures, while minimizing the permeability of the diverter pack. A smaller bi-modal distribution of DA-355 can be pumped to provide a far-field diversion.
