Oil and gas exploration frequently involves drilling through formations with high salinity or operating in environments with elevated temperatures. In such challenging conditions, the stability and effectiveness of drilling fluid additives are paramount. Polyanionic Cellulose (PAC) stands out as a superior additive due to its remarkable salt tolerance and high-temperature stability, making it a preferred choice for demanding drilling applications. At NINGBO INNO PHARMCHEM CO.,LTD., we provide PAC solutions engineered to perform reliably under extreme conditions.

One of the most significant advantages of PAC in oilfield drilling is its exceptional salt tolerance. Many drilling operations, particularly those involving offshore wells or formations containing high concentrations of salts (like sodium chloride, potassium chloride, or magnesium chloride), can degrade or neutralize conventional drilling fluid additives. PAC, however, maintains its effectiveness even in saturated brine environments. This is attributed to its stable anionic structure, which is less susceptible to flocculation or precipitation in the presence of high ionic concentrations. This property ensures that fluid loss control and viscosity modification are maintained consistently, regardless of the salinity of the drilling fluid or the formation fluids encountered.

Equally important is PAC's high-temperature stability. Modern drilling operations often reach depths where bottom-hole circulating temperatures (BHCT) can exceed 150°C (302°F) or even higher. Additives that degrade under such conditions can lead to a loss of critical fluid properties, necessitating frequent and costly adjustments to the mud system. PAC has demonstrated remarkable thermal stability, retaining its functional properties and performance characteristics at temperatures well above 150°C. This resilience ensures that PAC continues to provide effective fluid loss control and rheological enhancement throughout the drilling process, even in high-pressure, high-temperature (HPHT) wells. This reliability makes PAC a preferred material for operators who need to buy PAC that can withstand the rigors of deep drilling.

The combined benefits of salt tolerance and high-temperature stability make PAC an indispensable component for operators looking to optimize performance and minimize risks in challenging drilling environments. Its ability to maintain crucial fluid properties under adverse conditions translates directly into more efficient drilling operations, reduced fluid consumption, and lower overall project costs. When selecting drilling fluid additives, opting for PAC from a reputable supplier like NINGBO INNO PHARMCHEM CO.,LTD. guarantees access to a product that can reliably perform where others might fail, ensuring the integrity and success of your exploration ventures.
