Well drilling and stimulation

An optimized microbial control treatment program requires a strategy to address each of the three phases: preparing the water, decontaminating the well, and protecting the reservoir.

LANXESS recommends biocides based on the conditions of each phase, considering temperature, salinity, aerobic and anaerobic conditions, and the desired duration of control. Each application is different and requires a tailored program to meet the needs of the specific system.

钻井液在井钻使用最广泛ing activities. Compared to other drilling fluids, water-based systems are most prone to microbial contamination. LANXESS’ solutions help maintain system efficiency by protecting fluids from bacteria and enzymes that can cause fluid degradation.

Water treatment microbiocides help minimize bacteria, algae and biofilm formation – aiding in the prevention of microbial induced corrosion (MIC), mitigation of polymer breakdown and reducing well and reservoir souring.
