Abstract
Seawater injection is a common practice of secondary recovery for many deep water projects. However, injecting seawater into reservoirs can result in flow assurance issues such as barium sulfate scaling and reservoir souring. The percentage of seawater breakthrough is a key parameter towards understanding and assessing the severity of those problems and further develop effective strategies to mitigate their impact on production.
This project aims to evaluate the applicability of various produced water components as tracer for seawater fraction and seawater breakthrough calculations under different conditions by using ion monitoring and analysis method. Based on the performance of different ions, a seawater breakthrough model will be developed, and a detailed efficient guideline on tracer selection can be proposed based on different production scenarios.
