Each of these items play a important role on the drilling rig as a filtration system to extract solids from the mud and return cleaner mud to the active system. It controls mud weight and allows the rig to drill faster and keep the properties of the well-bore hole consistent so that producing formations

simultaneously forced against the rock at the bottom of the hole by a drill string consisting of hollow steel pipes of circular section screwed together. The cuttings produced by the bit are transported up to the surface by a drilling fluid‚ usually a liquid (mud or water)‚ or else a gas or foam‚ circulated in the pipes down to the bit and thence to the surface. The rotation is transmitted to the bit from the surface by a device called the rotary table (or by a particular drive head)‚ or by downhole motors located

companies place the tubing perforations below the casing perforations even if it results in a tubing arrangement where the tubing has no mud anchor. A shop-made two-foot perforated joint is used. The joint is closed on bottom and has dozens of ½-inch holes drilled into it. A collar is used to screw it directly under the seating nipple. This reduces the length of the pump gas anchor to one foot or less. Companies favoring this method maintain that it gives the highest daily average production. The most

precipitates alumina tri hydrate which is then calcined to aluminum oxide. A Bayer Process plant is principally a device for heating and cooling a large re circulating stream of caustic soda solution. Bauxite is added at the high temperature point‚ red mud is separated at an intermediate temperature‚ and alumina is precipitated at the low temperature point in the cycle. Bauxite usually consist of two forms of alumina - a mon hydrate form Boehmite (Al2O3.H2O) and a tri hydrate form Gibbsite (Al2O3.3H2O)
