POLYCORRECT
ToR 2458-130-97457491-2015
Polycorrect process fluid is intended for use in testing, developing, and killing oil wells bored using both, water-based and water-free solutions. The PF is prepared using the concentrate of Polycorrect and process water. The recommended concentration is 28 % (vol.). Polycorrect concenrate has a low freezing point (down to -50°Ñ), whereas water-based fluids reduce the hydrate formation temperature by 10 to 15°Ñ. The Polycorrect-based PFs are ecofriendly and have a high flashing point (more than 200°Ñ in open crucible). Polycorrect compound has no solid phase in solutions and manifestts weak boundary tension, which allows retaining the initial porosity and permeability of reservoir rock.
