Chemical Shale Instability & Inhibition Research Paper

Chemical Shale Instability & Inhibition - Research Paper Example From the discussion it is clear that understanding the overall behavior of shale is the core intention of this paper. Furthermore, the discussion is also aiming at understanding various types of shale drilling fluids. This also includes the use of the drilling fluids and their composition. The other key concept explored in te discussion is the mechanism involved in the development of new shale.This essay discusses Shale can be defined as a sedimentary rock which is fine grained and is composed of mineral rich mud. The mineral composition found in this mud is variable. When discussing about shale instability and inhibition. It is prudent to note that the interaction between water and the clay like material forung within the shale is the root cause (REFF). This interaction contributes to wellbore instability which thereafter result in formation of poor gause and many other anomalies. This paper targets discussing issue related to shale instability and inhibition, challenges faced and h ow to prevent such inconvenient precisely when drilling shale. There are many types of drilling fluids that serve different purpose based on the shale being encountered. For example; the drilling fluid can be air, liquid or foam which is colloid of liquid and air (REFF). The role of the drilling mud at this point is to dissipate the heat by circulating the drilling fluids (REFF). Moreover, the drilling mud also lubricates the bits and reduces friction.
