Effective rotary steerable drilling systems overcome most of the problems with steerable motors by providing continuos pipe rotation while drilling. This is accomplished, with the tool reported on in this paper, with a non-rotating steerable sleeve containing three extendable pads that push against the borehole wall.Continue reading “Rotary Steerable Drilling Systems”
Desilters is available in a large range of configurations including stand alone, over a shaker as a desilter’s bottom shaker or packaged with a supply pump as a mobile desilting unit.
The presence of large amounts of drilled solids in a drilling mud usually
spells trouble for the drilling operation. These solids adversely affect the performance characteristics of the mud and can lead to a multitude of costly hole problems.
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. The oil base can be diesel, kerosene, fueloil, selected crude oil or mineral oil. –wiki
