Corrosion Technologies

Magnet Impulse Detector

Magnetic-pulse defectoscope technology has no analogues in the world.

Work has been carried out on more than 2000 wells in the Middle East. A special feature of the method is the ability to study the technical condition in a multi-column structure, through the tubing with the definition of violations and thicknesses of the

2nd, 3rd and 4th production well casing. The technology allows:

-to determine the location of through violations;

-to determine the rupture of pipe in a two- well casing structure;

-to determine the actual intervals for installing sealing patches;

-to determine the actual depth of installing casing packers, etc.;

-to clarify the well design if there are up to four well casing;

-to check the compliance of the installation intervals of well casing sections with the design with different internal diameters and wall thicknesses;

-to determine the actual intervals for installing sealing patches;

-to determine the actual depth of installing casing packers, etc.;

-to determine the intervals of corrosion and the degree of wear of the well casing;

-to determine the intervals of column violations requiring repair;

-determine the thickness of the first tubing, second and third production well casing.

-Error in determining the pipe wall thickness, mm: – for a single-casing – 0.5mm., when measuring the production casing through the tubing – 0.7mm.

Corrosion inhibitor «Iproden K»

 

Iproden K corrosion inhibitors are a composition of nitrogen-containing organic compounds in a mixture of solvents.

Application: Protection of equipment in oil and gas production in the reservoir pressure maintenance system, in the water collection and treatment system, as well as in the oil collection system under conditions of hydrogen sulfide, carbon dioxide and acid corrosion. Effective in oxygen-containing environments. Technologically advanced, do not have a negative impact on the oil refining process and oil quality. Have a low freezing point – not higher than minus 50 ° C.

Provide effective protection of oil field equipment in both turbulent and laminar flow modes in a wide range of phase ratios: oil-water. Compatible with many demulsifiers used in the fields.

Exhibit bactericidal action against sulfate-reducing bacteria. Have an aftereffect.

 

Anticorrosion module

 for Tubing and Electric Centrifugal Borehole Pumps from corrosion

Galvanic protection

 Anticorrosion module (AKM) is galvanic protection developed by our company based on many years of experience. The team of our company comprises former lead specialists who come from Geophysics Research Institute and have many years of experience in this field.
Corrosion damage of borehole equipment is a serious problem and huge financial losses for the oil and gas industry. Annual global financial losses are estimated at $2.2 trillion and those in our country are at $6.7 billion by estimate in 2015, while a quarter of those losses can be avoided using science-based corrosion protection methods.
We offer a technical solution based on the same time-tested and well-proven physical and chemical properties of non-ferrous metals.
The product Anti-corrosion module – AKM (Figure 1) is designed to improve the efficiency of oil production in difficult conditions and combat corrosion in the tubing string (tubing) / production pipes, the casing string of an oil and gas well and downhole pumping equipment (DPE) of oil and gas wells, as there is a struggle with paraffin and salt deposits.
 

The product is completed with elastic brush disks, which provide equalization of potentials of the downhole pumping equipment with the casing string. An additional purpose of the brush assembly is to dampen the radial oscillations of downhole pumping equipment in the well with the filtering effect of mechanical impurities entering the pump flow path. The body of the product ensures safe installation, operation and prevents the ingress of mechanical impurities from downhole pumping equipment and tubing to the bottom of the well.
