Oil-based mud is a drilling fluid used in drilling engineering. It is composed of oil as the continuous phase and water as the dispersed phase in conjunction with emulsifiers, wetting agents and gellants. Water-based fluids (WBFs) are the most widely used systems, and are considered less expensive than oil-based fluids (OBFs) or synthetic-based fluids (SBFs). The OBFs and SBFs—also known as invert-emulsion systems—have an oil or synthetic base fluid as the continuous(or external) phase, and brine as the internal phase. The oil-based fluid is called OBM, and the water-based is named KCl. In other references [4] in which this specific oil-based fluid is mentioned, it is named OBM B.

Oil-based Mud (OBM) and Synthetics-Based Mud (SBM) Oil-based mud is a drilling-fluid system composed of base oil, water, additives and chemicals. Depending on the application and regulatory and environmental requirements, the base oil could be diesel, kerosene, low-toxic mineral oil or synthetic oils, such as esters, olefins or paraffins.

This oil-based drilling fluid system has excellent comprehensive properties, and it could resolve the contradiction between safety drilling of complicated deep wells. At Croda we offer a range of high performing additives for drilling fluids, providing The drill muds used today are water-based mud, oil-based mud, and 

At Croda we offer a range of high performing additives for drilling fluids, providing The drill muds used today are water-based mud, oil-based mud, and  Muds based on a water/oil emulsion (known as “inverts”) are used for drilling deeper wells as they have better lubricating properties and are more temperature   12 Nov 2018 Different types of drilling fluid based such as water based, oil based and synthetic based are commonly used in the oil and gas fields.
