Avoiding the formation of sulfate-reducing bacteria (SVB) in water and hydrogen sulfide in the associated gas

1. Collecting information on the current state of contamination of the reservoir and the use of reagents against sulfate-reducing bacteria (SBB) in the PU deposits 2. Sampling and determination of the hydrogen sulfide content in the associated gas for all gas sources. 3. Sampling and determination of the degree of bio-contamination SBV on objects (no more than 4 selections from each object) 4. Sampling and determination of hydrogen sulfide content in the gas of producing wells in problem areas. 5. Analysis of the effectiveness of the use of reagents and technology of injection of reagents and other methods of combating SVB. The formation of a list of negative factors that stimulate the growth of SVB and reduce the effectiveness of methods to combat them. 6. Analysis results processing and mapping of problematic participants/GU 7. Development/selection of bactericides and other reagents for the control of SVB and technologies for the use of reagents 8. Selection of BKNS (no more than two) for shock injection bactericide on problematic plants according to the results obtained. 9. Selection of no more than 10 injection wells for bactericidal treatment according to the results obtained. 10. Shock injection on selected BKNS. In this case, the scheme of injection of the bactericide to the BKNS without measurement according to the current treatment scheme (2kg/m3). BKNS response time is 24 hours 11. Targeted injection into injection wells in problem areas (based on the results of analyses for hydrogen sulfide content in problem wells GU) based on the dosage of 2-3 kg/m3 of well intake according to the current treatment scheme. 12. 5 wells at a dosage of 2 kg/m3 13. 5 wells at a dosage of 3 kg/m3 14. Sampling to determine the hydrogen sulfide content in the gas for GCS reacting to BCS, where the injection of a bactericide. (no more than 4 selections from each facility within 60 days) 15. Sampling and determination of hydrogen sulfide in the gas of producing wells (with a high content of H2S), where the bactericide was injected into injection wells. To determine the treatment efficiency period, it is necessary to take at least 4 samples from wells within 60 days. 16. Development of a methodology for determining the effectiveness of the effects of bactericides and reagents on the reservoir Requirements for organization and implementation. 17. - In order to collect information and study the operational documentation, the Contractor visits the location of the facility. 18. - The entire scope of technical inspection services The contractor provides services on its own, with devices, tools, equipment and at its own expense, including accommodation and meals. 19. -Availability of an accredited or certified laboratory from the Contractor (own or leased, or a contract for the provision of services). The supporting documents are an accreditation certificate or a Certificate of assessment of the measurement condition or a contract for the provision of services. 20. - If necessary, the Customer provides access The Contractor is transferred to the production units and allows the Contractor to collect the necessary technical data in accordance with the requirements.
