Problem Solving of Injection Water Quality by Using Anthracite and Activated Carbon Filter Media for Water Flooding Need in X – Oilfield

Abstract

Produced water is utilized as injection water for water flooding purposes. When untreated injection water with poor quality is introduced into the formation, it can lead to severe plugging issues. This is primarily due to the poor quality of the water, characterized by high levels of solid particles, elevated turbidity, a high scaling index, significant oil content, high TSS concentration, and a high RPI. The application of anthracite and activated carbon filter media has been shown to effectively reduce the scaling index, oil content, turbidity, particle size, TSS, and RPI in the injection water. These filter media exhibit enabling them to filter out insoluble materials from the injection water. By evaluating the effectiveness of different filter media on injection water quality, it is possible to select a filtrate with improved water quality, characterized by a clear appearance and minimal solid particles. The resulting filtrate demonstrates very low TSS concentrations and a significantly reduced RPI value. Overall, the filtrate can be classified as high-quality injection water suitable for water flooding applications. The morphology of TSS before and after filtration through anthracite and activated carbon filter media can be detected by using SEM.
