POTENTIAL USE OF BASALTIC SOIL FOR DRILLING FLUID

Abstract - Drilling fluid or drilling mud is a critical component in the drilling process, where it provides the gel to efficiently lift cuttings, maintain stable wellbore and produce sufficient hydrostatic pressure that could prevent the influx of formation fluids into the wellbore. For over eight...

For over eight decades, drilling grade barite remains to be the most profound weight material used to adjust drilling mud densities around the world. However, barite resources globally are depleting especially in terms of its quality, economical viability and attainability – thus making it more expensive.

Basaltic clay soil is seen as a potential alternative to be utilized in drilling fluids additive and also as barite substitute for the weighting agent. Based on literature reviews the significance of using basaltic soil is that is has the gel characteristics to lift up drilled cuttings, produces suitable mud weight and economically inexpensive for its abundance.
