Silicate-Based Drilling Fluids Deliver Optimum Shale Inhibition and Wellbore stability

Along with exorbitant costs and safety considerations, drilling and exploatory well where conventional mud systems could not maintain wellbore stability and trouble-free drilling, also posed the additionally difficult challenge of selecting a fluid system stable against multiple contaminants and flexible for a broad range of densities. The demands are compounded dramatically when designing the system and information to support the decision is poor. This paper details the design and performance of a silicate-based fluid, which is an inhibitive mud system formulated with a soluble silicate for maximum shale inhibition.
