Implementation of selective flocculation process in drilling operations to optimize per-flex fluid volume consumption and reduce the carbon footprint

One of the significant challenges faced by the oil and gas industry is the reduction of the carbon footprint associated with drilling operations. This paper presents a case study on the implementation of a selective flocculation process to optimize the consumption of PER-FLEX fluid, a high-performance water-based mud (WBM), during drilling operations. Conducted in a Colombian oil field, this study demonstrates how the adjustment of polymer concentration and injection rates in the flocculation process can reduce the need for fluid dilution, thereby decreasing water and chemical consumption, waste production, and CO2 equivalent (CO2 eq.) emissions. The findings highlight the effectiveness of selective flocculation in enhancing drilling fluid performance and contributing to sustainability goals.
