SWT Multifunctional method with the use of chemical compositions for saline deposits removal in pipelines

2. Global Munay Service About Us
Our company was established jointly with a Russian company in 2010 as R&D “KMHS” LLP. As a result of internal reorganization in 2013, it was transformed into 100 % Kazakhstan Company: Global Munay Service LLP.
Our engineering and technical team has a good professional experience in
enhanced oil recovery technologies, commissioning of wells after
drilling and well workover at the oil fields in Russia and Kazakhstan.
We have great research and methodological knowledge base.
We cooperate and exchange experience with the leading
scientific and research institutes, design institutes and design bureaus.

4. Global Munay Service Originality of the Method
The method allows the movement of fluid (water, chemical reagents, oil) in bottomhole zone or in pipelines, so the waves are created and shock wave pulses occur.
We finalized, upgraded and improved the special device (valve) and received a document of title - patent No. 933 on the invention of utility model "DOWNHOLE VALVE WITH PNEUMATIC ACTUATOR". "

5. Global Munay Service Multi-functionality of the Method
The Method is used for:
redistribution of filtration flows
assurance of injectivity in injection wells
increase in the rate of production wells
squeeze cementing
conformance control
water production restraining
removal of saline deposits in pipelines
All of the above is provided by individual selection of chemicals and polymers depending on the requirements set by the customer
Since 2012 our team is successfully using SWT technology at Zhetibai oil field

Chemicals: character of deposits
36% Asphalt, resin, and paraffin deposits (ARPD)
38% Carbons(+rust near the surface of the pipe)
26% Barium sulfates with the inclusion of sand
Pipes examination has revealed the general character of deposits in Kalamkas oil field

Dissolution result
(with the use of chemical reagents and circulation)
ARPD solvent before and after loading of test samples
Dissolution of the deposit with a special solvent

8. Global Munay Service Chemicals: Tests The Tests made has shown that:
1-stage: Preliminary treatment of saline deposits with ARPD solvent. Overall dissolution of saline deposits amounted to 35%-38%.
2-stage: Treatment with the use of specially selected solvent. Overall dissolution was up to 43%.
Important: During all types of treatment the static mode was used.
Circulation and/or solvents flow movement increases the effect of treatment.
Sample - initial
Sample – after the use of solvents (1 and 2 stage)

10. Global Munay Service Purification process
For the solution of tasks for saline deposits removal in pipelines the special device and individually selected solvents are used.
Pulses + movement of chemical compositions.
Joint (simultaneous) impact on the deposit significantly increases the effect.
pressure differential results in breakdown of saline deposits
Movement of reagents
12-20 times per minute
Velocity m/sec
Use of specially selected chemical compositions
