The presentation key objective is to show how synergizing the use of corrosion inhibitor and demulsifiers has enhanced the performance and optimized the cost of Oil Field Chemical (OFC) treatment at Safaniya Onshore Arab Heavy wet crude handling facilities. The various steps involved in synergizing the use of oil field chemicals at Safaniya Onshore Arab Heavy wet crude handling facilities have also been discussed. The key performance factors used to assess the overall impact of the process including the total cost of chemical treatment, the effective mitigation of corrosion in the system, the oil in water content in the produced water system, other process parameters like emulsion and foaming tendency were addressed. Synergizing the use of OFC at Safaniya Onshore Arab Heavy wet crude handling facilities has resulted in chemical treatment cost savings of approximately $2.0 MM per year, better treatment of produced water system and improved corrosion mitigation efficiency of 99.6%.

This paper addresses how high resolution electromagnetic induction was used to study, assess and map the overall well casing integrity of offshore wells and to enable predictions of casing leakage based on the extent or severity of the casing corrosion log. The objective of the paper is to show how proactive detection and prevention of leaks before they occur have guaranteed continuous operation excellence, safety and environmental compliance.These studies were carried out to understand the nature of the corrosion observed. In addition, several other technologies were deployed to effectively detect leaks and further sketch out their location. The lessons learnt and experience acquired during the monitoring and evaluation of casing integrity will be shared.The new technology was used as a tool to establish a casing integrity baseline for an entire field and articulated the new strategic corrosion master surveillance plan. Using the new technology has resulted in a significant reduction in the frequency of routine conventional temperature surveys and therefore optimized resource utilization to foresee other essential jobs.
