JSC “Vistex” is a technology developer and manufacturer of materials for the petrochemical sector.

 

"Cleaning of oil pipelines"


The primary tasks of the development of JSC “Vistex” are the high adaptability of the application and a significant minimization of the cost of the work.

Employees of the "Innovation Department" have 25 years of experience in cleaning the internal cavity of oil and product pipelines from asphalt-resin-paraffin deposits (AFS), mechanical impurities, deformed treatment devices (OS), gas plugs, etc. in the system of Transneft PJSC and other main oil pipelines.

Cleaning technologies * Vistex JSC, allow to displace an oil product or NGL from a pipeline without mixing with an expelling agent, with water or gas. The work is carried out using viscoelastic compositions based on gel compositions. Substitution of oil during pressure testing occurs without the formation of a water-oil emulsion.

Cleaning with the use of dispersant inhibitors is carried out using standard oilfield equipment (UNB unit) and at any accessible point in the pipeline, without reference to the chambers for launching the scraper.

In-line diagnostics is carried out together with and without treatment devices (OS).

Our technologies allow us to work in conditions with sharply negative temperatures, with complex reliefs of sections of the route and a variable diameter of the pipeline.

Cleaning and in-line diagnostics using dispersant inhibitors was carried out in more than 120 sections of the pipeline. Among them:

Oil pipeline Vatiegan - April, Transneft Siberia, JSC (Transneft PJSC),

Sites in the Surgut UMN (Transneft Siberia, JSC),

OJSC North-West MN (PJSC Transneft),

Transneft Volga Region, JSC (Transneft PJSC),

LLC Gazpromneft-Khantos (PJSC Gazprom Neft), etc.

"Foam compositions"


A separate area of the company’s activity is the development of “foam gel formulations” to prevent the evaporation of oil products from tanks.
