Masterbatch-polyester

Masterbatch (superconcentrate)-polyester is used for drilling fluids processing in the primary opening of productive layers by vertical, directional, horizontal wells drilling, as well as their overhaul (process fluids for perforation, damping, conservation), both on land and sea.


SK-polyester (container: 50 kg, 200 kg, 1000 kg).

"Masterbatch-polyester (SK-polyester)" – surfactant for composing simple polyethers.

"SK-polyether" preserves natural filtration properties of reservoir rocks by reducing the surface tension of the drilling mud filtrate and hydrophobization of the pore surface of the formations. It increases inhibiting activity, helps reduce fluid, improve the rheological properties, and reduce downhole friction.

Application

Used for processing drilling fluids during in the primary opening of productive formations by vertical, directional, horizontal wells drilling, as well as their overhaul (process fluids for perforation, damping, conservation), both on land and sea.

Competitive advantage

  • Does not foam drilling mud
  • In accordance to the effectiveness of reducing the surface tension of the drilling mud filtrate, there are no analogues in Russia
  • Compatible with all materials used for the preparation and regulation of the properties of technological solutions
  • Company’s secret recipe
  • The market price is usually lower in comparison with competitors up to 20%
  • We deliver!

Usage recommended

The optimal reagent additive in clay drilling fluids is 1.5-2.0 %, and in clay-free – 0.5-1.0 % for the marketable product. The interfacial tension at the boundary of the mud – hydrocarbon filtrate drilling is reduced to 5-15 mN/m. The wetting angle edge is 110-120 degrees. At the same time, the addition of 1.0 % "SK-polyester" reduces the filtration of the solution by 10-20 %.

"SK-polyester" on the parameters of acute toxicity refers to low-hazard substances (IV hazard class according to GOST 12.1.007-76). The product has:

  • Sanitary-epidemiological conclusion №16.11.10.222. P. 004059.12.06 from 19. Dec.2006.
  • Certificate of conformity №TEK RU. HP06.N01476 from 21.Dec.2006.
  • Certificate for use of chemicals in technological processes of extraction and transport of oil No. 153.39.RU 245860.01362.12.06 from of 21. Dec.2006.

SK-polyether is approved to be used on the territory of the Russian Federation as a reagent for drilling fluids, perforation, damping, and preservation of wells and is included in the industry register "List of chemical products approved for usage in the oil industry".

Masterbatch polyester has been successfully used in such companies as "NK "Rosneft", "Vankorneft” since 2007.
