Distribution characterization and extraction prospects of resources in gas produced water:Strontium and bromine resources in gas produced water in the Eastern Sichuan area as an example
Gas produced water is originated from formation associated water produced during oil and gas production operations,which is characterized by numerous types,high mineralization and complex pollution components.Through sampling,testing and analyzing gas produced water in the Eastern Sichuan area,it is found that the carboniferous formation is rich in mineral resources,such as strontium(up to 814 mg/L),bromine(up to 717 mg/L),which is much higher than the content in the brine of Qaidam Basin salt lakes or seawater.And currently,China's strontium ore and bromine are in a situation of high import demand and supply shortage.By clarifying the strontium and bromine recovery techniques and evaluating the preliminary economic feasibility of potential mining,it is found that there are significant prospects of development and utilization.This study aims to provide scientific basis for the extraction of strontium and bromine resources in gas produced water in the Eastern Sichuan area and to establish the foundation for better sustainable development and resource utilization of oil and gas fields.
