Drilling operations continue to get more difficult particularly in the  mature fields  as the oil company try to get more information about properties of these reservoirs, verify the fluids contact, assist to delineate new development locations, and determine the proven reserves. As wells become more challenging in onshore mature fields areas such as oil field in  sirte basin , operators are finding it difficult to drill efficiently to total depth using conventional water-based mud (WBM) systems and often have to rely on oil-based mud (OBM) to reach their drilling objectives. Although there are definite technical benefits associated with OBM, these fluids are often a costly solution with regard to disposal costs, lost circulation issues and regulatory/environmental considerations. As a result, operators are constantly challenged to balance performance requirements with environmental, waste disposal, economic and logistical drivers.

In response, new high-performance WBM (ultra drilling mud system  solutions have been developed to fill the performance gap between conventional water-based and oil-based muds for onshore drilling applications. The newest generation of Ultra Mud weight systems is designed to provide superior performance and environmental compliance while maintaining cost competitiveness compared with conventional WBMs.
