Biostabilizer for reducing microorganisms in geothermal boreholes
A recently granted patent (Publication Number: US11884870B2) outlines a method for reducing microorganisms within a geothermal borehole. The method involves providing water with a hardness of at most 20° dH and adding an environmentally compatible biostabilizer, which includes organic acids like hop acids, to form a process fluid. This fluid is then pumped into the geothermal borehole, where it acts as a drilling fluid. Additional additives such as defoamers, gelling agents like biopolymers, and water-softening agents can be included in the process fluid to enhance its effectiveness.
Furthermore, the patent details the composition of the biostabilizer, which may consist of resin acids, fatty acids, or hop acids like humulone and lupulone. The process fluid can also contain antimicrobial agents and additional biostabilizers for comprehensive microorganism reduction. The hardness of the process fluid can vary from 5° to 20° dH, with options for different levels of hardness to suit specific needs. The patent also covers the preparation of the process fluid, emphasizing the importance of using environmentally compatible biostabilizers to ensure effective reduction of microorganisms within geothermal boreholes.
