PROVISION OF AL RIFAI SEWAGE WATER COMPATIBILITY STUDY FOR PETRONAS CARIGALI IRAQ
This project focuses on advanced water compatibility and production chemistry evaluation for oil fields water injection systems, ensuring safe and efficient operations through integrated field and laboratory studies.
The scope includes comprehensive water sampling, full chemical and microbiological analysis, scaling tendency prediction, reservoir souring prediction assessment, filtration testing, and biocide performance evaluation.
Subcontractor Scope – Iraq (Petro-Baghdad)
Petro-Baghdad is responsible for all onsite and laboratory water testing activities in Iraq, including:
- Full surface, subsurface, third river, produced water and sewage water samples collection, preservation, and shipment
- On site testing especially some biotests.
- Full water chemistry analysis (physical, chemical, and ionic composition)
- Microbiological testing and monitoring (SRB, GAB, GAnB, bacterial counts)
- Nutrient and organic content analysis
- Complete biocide and microbiological control program, including dynamic and static testing and time-kill studies (NACE TM0194)
Advanced Laboratory Studies – Main Contractor (PanTerra, Netherlands)
Advanced experimental and modeling work were conducted at PanTerra laboratories in the Netherlands, a specialized facility for petroleum and reservoir chemistry studies. Including:
- Scaling tendency prediction and chemical modeling
- Static and dynamic scale confirmation tests (Jar Tests)
- Core flood and core blocking experiments for injectivity and formation damage evaluation
- Water–rock compatibility and fines migration studies
- Water filtration performance testing under simulated field conditions
- Reservoir souring modeling and H₂S prediction studies
Project Objective
The project integrates field data and advanced laboratory analysis to evaluate water compatibility risks such as scaling, microbial growth, injectivity loss, and reservoir souring. The results support optimized chemical treatment strategies and improved long-term performance of water injection systems.
