Case Study: FeS Dissolution and Iron Chelation of ScavSol AF 50 vs THPS
Introduction: Solugen was asked to help solve the costly iron sulfide issues that an oil and gas operator was experiencing in the Permian Basin. To do this, water samples were taken in the field and bottle testing was completed with multiple chemical formulations. This testing is based on qualitative results to establish efficacy to determine next steps.
The Problem: An oil and gas producer in the Permian Basin using THPS was experiencing iron sulfide deposition in their oil and gas processing system. The system was producing approximately 186 barrels of oil, 820 barrels of water, and 214 MSCFD of gas via artificial lift jet pumps and standard separation equipment.
The effects of uncontrolled iron sulfide in the processing system resulted in estimated penalties due to high basic sediment and water (BS&W) measurements, increased corrosion rates, employee overtime to address process flow, and increased chemical costs for correcting interfacial pads and water quality.
The total cost to the operator was calculated at over $200,000/year.
