Title : Automation of crude oil emulsion analysis using advanced colloidal technology
Abstract:
Crude oil emulsions form during extraction processes when water becomes finely dispersed within crude oil—a phenomenon that occurs naturally due to the simultaneous presence of oil and water under high-pressure subterranean conditions. Analyzing the destabilization of water-in-crude oil emulsions has traditionally been challenging, relying heavily on manual labor and skilled expertise to conduct the Emulsion Separation Index (ESI) test. As oil extraction advances into more complex phases and involves heavier crude oils, the resulting emulsions become increasingly stable and resistant to traditional separation methods requiring more time and effort in the laboratory testing. This work presents an advanced colloidal technology that integrates the Turbiscan Tower Instrument with a custom data processing program to automate emulsion separation testing. The system captures readings at two-minute intervals using transmission and backscattering techniques, providing real-time information on the volume and clarity of separated water. This method has been applied in various scenarios, including ranking different demulsifiers proposed for specific gas oil separation plant (GOSP) feeds and accurately measuring the oil-water phase inversion point, which marks the transition of the emulsion from water-in-oil to oil-in-water. By automating emulsion testing procedures, the proposed method reduces dependence on manual interventions, improves testing accuracy, and accelerates the assessment process. This protocol offers valuable insights for enhancing operational efficiency and informing strategic decision-making processes in the petroleum industry. Adopting this spectroscopic approach represents a significant advancement in crude oil emulsion testing, providing swift and detailed characterization that benefits both operational practices and scientific research. Furthermore, its ability to deliver precise and timely data contributes to better management of extraction processes and optimization of resource utilization.
