.... These conditions often necessitate the use of oil-based muds for satisfactory drilling performance. However, the use of diesel or mineral oil as base fluids poses significant environmental risks due to their heavy metals, dispersed oil, aromatics and alkyl phenols, and n-olefins content, all of which can...
