Water Based Mud (WBM) is a common type of drilling mud that widely used in drilling operation. Wide acceptance of WBM for drilling is hugely due to the reasons of existence of stringent environmental policies, and high hydrocarbon exploration cost.

Fluid loss into formation is a problematic situation whereby invasion of water will leads to formation damage and wellbore instability which can jeopardize the formation evaluation job.
