The model tests are performed to investigate the performance of drilling fluid with different mix designs for use in borehole collapse prevention. The model tests are carried out considering offshore drilling procedures. It is shown that the addition of polymer to the attapulgite clay improves the performance of the drilling fluid for preventing the borehole collapse
