High Performance Water Based Mud
Commonly known as HPWBM, the High Performance Water Based Mud systems are reformulated polymer water based systems designed to replicate the performance benefits of Oil Based Mud systems. HPWBM are designed to be able to achieve OBM benefits like shale stability, clay inhibition, lubricity, high ROP, while minimizing bit balling without the downside of adverse environment impact. In many wells a regular Water Based Mud (WBM) is used in shallow sections but due to water sensitive formations and high friction, Oil Based Mud systems are required in deeper horizons. In operations where cutting collection and environmentally safe waste disposal costs are high, HPWBM can prove to be more cost effective solution.
