Abstract
This paper presents the results of a reduced-scale physical model investigation into the effect of drilling fluid with different mix designs for use in offshore bore hole collapse prevention. Compare the bentonite and Attapulgite use. Reduced-scale model tests were then carried out considering field procedures for cases with decomposed granitic soil with fines and a sand with various drilling fluids with different mix designs. The results were indicated that the addition of polymer to the bentonite based drilling fluid decreases the amount of injected drilling fluid and increases the final depth of excavation. Also revealed that the effect of polymer on the performance of drilling fluid is more pronounced in the decomposed granite soil with fines than sand. Practical implications of the findings from this study are discussed in detail.
