Oil-based fluids which are used today which is formulated with diesel, mineral oil, or low-toxicity linear olefins and paraffin. Where olefins and paraffin where it is referred to as synthetics where some are derived from distillation to the crude oil and chemically synthesised with smaller molecules. Where Oil Drilling Mud Fluids are formulated with synthetic-based oil with water phase. It has the stability of the internal brine or water phase which is monitored with a predetermined value. 

There it has a thigh salinity phase where you have an inverted emulsion which helps to stabilise reactive shale and prevent swelling. Where drilling fluid is formulated with diesel or synthetic-based oil and has no water phase which is used to drill long shale intervals and salinity the formation of water. It has a Fluid Loss Agent which is eliminating the water phase with oil drilling fluid which preserves the shale stability in the interval. 

The current base oil in use where paraffin is an oil which has carbon hydrogen with single bonds and chains with others. Olephins are the oil which has carbon- hydrogen with double bonds and either alpha olephins. The esters oil are modified vegetable oils, where primarily from palm oil. It has different oil drilling mud fluids which will help the company to build success. 

Invert Emulsion Drilling Mud: Where diesel and mineral oil are also known as invert emulsions which is inhibitive and resistant to contaminants and is stable with high temperature and pressures. It is a typical il-based mud where it has the fluid of choice for driving troublesome shale sections and extended reach wells which are otherwise prone to a pipe and sticking the problems. Where drilling efficiency of the OBF system. Where drilling fluid system types were subject to stringent disposal regulations. 

Synthetic-Based Drilling Fluids: It has synthetic types of drilling fluids which are developed to provide which is highly regarded drilling performance characteristics where it has conventional OBFs which is significantly reducing the toxicity of the fluid. Where it consequently is almost universally offshore and continues to meet the Oil Drilling Mud Chemicals. It is almost universal offshore and they continue to meet increasingly rigorous toxicity. 

Emulsion-Based Drilling Fluids: Where SBF is formulated with an eater and blended to become which is widely used and works with a deep-water operation where the temperature range which given well. It has a fluid loss agent where it contains no clays and treated lignites, rheological and fluid loss control properties which are maintained with specially designed fatty acids and surfactants. Where it provides a stable viscosity with rheological properties.
