  • Oil Based Mud

    Oil Based Mud (OBM) is used for many reasons such as increased lubricity, greater cleaning abilities with less viscosity.
    Also OBM can withstand greater heat without breaking down.

Water Based Fluids

Air/water: Water added to increase viscosity, flush the hole, provide more cooling, and/or to control dust.

rotaryone3dWater-based mud (WBM): The most basic water-based mud system begins with water, then clays and other chemicals are incorporated into the water to create a homogeneous blend resembling something between chocolate milk and a malt (depending on viscosity). The clay (called "bentonite" in its form) is usually a combination of native clays that are suspended in the fluid while drilling, or specific types of clay that are processed and sold as additives for the WBM system. The most common of these is bentonite, frequently referred to in the oilfield as "gel". Gel likely makes reference to the fact that while the fluid is being pumped, it can be very thin and free-flowing (like chocolate milk), though when pumping is stopped, the static fluid builds a "gel" structure that resists flow. When an adequate pumping force is applied to "break the gel", flow resumes and the fluid returns to its previously free-flowing state. Many other chemicals (e.g. potassium formate) are added to a WBM system to achieve various effects, including: viscosity control, shale stability, enhance drilling rate of penetration, cooling and lubricating of equipment.

Unweighted drilling fluid applications

In unweighted drilling fluid, a centrifuge may be used to remove particles smaller than a desilter can remove. The D 50 cut point is around 2 to 10 microns as opposed to 15 to 20 microns for a desilter. The heavy slurry is discarded and the light slurry is retained, identical to that of a desilter.

Centrifuging unweighted drilling fluids removes drilled solids that are too small to be removed by other separation devices. A dry discharge is desired, which reduces total liquid consumption and disposal volumes, and is an important consideration if the fluid phase contains additives.

Centrifuges can also be used to process hydrocyclone underflow.  In this case, the cone apex may be opened to produce a wetter discharge yielding a lower solids concentration to be centrifuged. Frequently, additional fluid from the desilter overflow is added to the underflow to assist centrifuge processing.  Decanting centrifuges are used to process unweighted oil mud.

Weighted drilling fluid applications

In weighted drilling fluids, the heavy slurry from a centrifuge contains appreciable quantities of barite. Both streams can contain low-gravity solids and barite. Usually, most of the large drilled solids and large barite are contained in the heavy slurry, and most of the colloidal barite and drilled solids are contained in the light slurry. A centrifuge is effective in reducing the colloidal concentration in a weighted drilling fluid.
