No full textShale inhibitors are essential chemical additives used in oil and gas drilling fluids to mitigate the swelling, dispersion, and disintegration of shale formations encountered during drilling operations. Shale, which contains reactive clay minerals such as smectite and illite, tends to absorb water from conventional drilling fluids, leading to structural instability, wellbore collapse, and reduced drilling efficiency. Shale inhibitors function by altering the hydration behavior of clay minerals, either by blocking water uptake or by stabilizing the clay structure through ionic exchange or encapsulation mechanisms. Common types of shale inhibitors include potassium chloride (KCl), amine-based compounds, glycols, and polymeric inhibitors, each offering varying degrees of effectiveness depending on formation characteristics and operational conditions. The use of shale inhibitors enhances wellbore stability, reduces non-productive time, and improves overall drilling performance. This paper reviews the mechanisms, classifications, and field applications of shale inhibitors, highlighting their critical role in maintaining drilling fluid integrity and optimizing well construction in shale-rich formations
