A mixture of clay, water, chemical additives, and weighting materials that flushes rock cuttings from a well, lubricates and cools the drill bit, maintains the required pressure at the bottom of the well, prevents the wall of the borehole from crumbing or collapsing, and prevents other fluids from entering the well bore.
A special mixture of clay, water, or refined oil and chemical additives pumped downhole through the drill pipe and drill bit. The mud cools the rapidly rotating bit, lubricates the drill pipe as it turns in the well bore, carries rock cuttings to the surface, serves as a plaster to prevent the wall of the borehole from crumbling or collapsing and provides the weight or hydrostatic head to prevent extraneous fluids from entering the well bore and control downhole pressures that may be encountered.
A mixture of clay, water, chemical additives and weighting materials that cool and lubricate the drill bit, carry rock cuttings from the well and control natural formation pressures.
a mixture of clays and chemicals and water; pumped down the drill pipe to lubricate and cool the drilling bit and to flush out the cuttings and to strengthen the sides of the hole
A common term for drilling fluids.
Mixture of water and other additives that circulate within the well. It has the purpose of cooling the bit, removing rock cuttings, preventing cave in and averting a blowout
A special mixture of clay, water, and chemical additives pumped down hole through the drill pipe and drill bit. The mud cools the rapidly rotating drill bit; lubricates the drill pipe as it turns in the well bore; carries rock cuttings to the surface; and serves as plaster to prevent the wall of the bore hole from crumbling or collapsing. Drilling mud also provides the weight or hydrostatic head to prevent extraneous fluids to entering the well bore and to control down-hole pressures that might be encountered.
A specially formulated fluid used to lubricate the drill bit and remove drill cuttings. Different fluid bases exist for different types of mud. They may be water based (WBM), mineral oil based (OBM), or synthetic oil based (SMS). Muds have to be carefully formulated to match the varying geological, temperature, and pressure conditions that are met as an oil well is being drilled.
A mixture of clays, water, and chemicals used in drilling operations to lubricate and cool the drill bit, carry drilling wastes to the surface, prevent the walls of the well from collapsing, and to keep the upward flow of oil or gas under control.
Specialized mud mixed at the drill site and pumped down the drillstring and up the annulus to prevent blowouts, remove cuttings and cool and lubricate the bit.
A slurry of water mixed with clay that oil drillers use to cool a drill bit and flush rock cuttings up and out of the hole.
The circulating fluid used to bring cutting out of the well bore, cool the drill bit, and provide hole stability and pressure control. Drilling mud includes a number of additives to maintain the mud at desired viscosities and weights. Some additives that may be sued are caustic, toxic, or acidic.
Drilling mud, also called drilling fluid, is a lubricant used while drilling oil and natural gas wells and in exploration drilling rigs.
