The DO-STIM™ 700-AR Series is a new line of environmentally friendly acid replacement solutions for use in acidizing treatments, which have ultra-low corrosion to tubulars, and removes the need for multiple additives. Ultimately, this new and innovative single solution product range reduces operational complexity and footprint, while increasing production benefits seen after treatments.
The DO-STIM™ 700-A line of acidizing treatments are formulated such that they have a slower reaction rate than Hydrochloric Acid (HCl), and therefore able to reach further into the formation and achieve better worm holing effects and reach deeper penetration into the reservoir, and remove the risk of face dissolution. The chemistry of the fluid also means that is has ultra-low corrosion effects, reducing the risk of damage to casing, tubing, and other downhole components, and is significantly safer to transport and handle given its low fuming nature. It has superior crude compatibility, resulting in the significant decrease in post-treatment damage, and rarely needs additional additives (pending laboratory testing).
This is a single additive solution, and can arrive as a concentrate (to be diluted either by batch mixing, or on the fly) or in a ready to pump solution at concentrations up to 50%, depending on the intended application.
