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

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. 2015

About SWT method (Shockwave treatment) Global Munay Service About SWT method (Shockwave treatment) SWT Multifunctional Method Downhole valve with pneumatic actuator (special device) Chemical compositions 2015

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". " 2015

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 2015

Global Munay Service 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 2015

Global Munay Service Chemicals: reagents selection before after 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 2015

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) 2015

Global Munay Service Wellhead connections scheme during SWT for saline deposits removal in pipelines Saline purification technology Installation of SWT, placement of special-purpose machinery and flow lines hydraulic test. Preparation and injection of buffer fluid in the amount of 0,5 -1m3 visco-elastic mud Injection of ARPD solvent Preparation and injection of visco-elastic mud Injection of saline deposits solvent with regard to estimated time of reactions with SWT Drainage of the reaction products and transport to landfill Special device with pneumatic actuator Device control block Manometer Isolation valve Outer hose Discharge drum Receiver Water distribution unit SIN-32 Tank truck Fast dismountable screw-nut Isolation valve Pipeline 2015

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 - 1350-1550 m/sec Use of specially selected chemical compositions 2015

Global Munay Service Comparison – efficiency The cost of SWT services is constant regardless of pipes diameter 2015

Effective and mutually profitable business relationship Global Munay Service Our Priority: Effective and mutually profitable business relationship 2015
