Drilling fluid technology is in constant evolution due to  rapidly  expanding needs due to more severe conditions, such as high temperature and pressure, tight gas and shale-gas reservoirs..., increasing technical demands, such as increased lubricity requirements in air drilling and growing restrictions on oil-based systems, such as environmental remediation. To comply with the new government regulations restricting the use of some technologies or practices, drilling fluid manufacturers have responded by developing acceptable alternatives. However, these solutions usually have substantial added costs and limitations that are sometimes prohibitive. In summary, drilling fluid development needs to encompass the design of new environmentally acceptable WBM and oil-like systems that will provide alternatives to OBM.
