The key factor driving rig selection is its ability to turn the drill string measured in horse power.TVD is important because it gives the drilling engineer an idea of the pressures and temperatures that will affect the drill string and the drill bit.Netwas Group OilAmodern drill collar is about 30 ft long,and the total length of the string of drill collars may range from about 100 to 700 ft or longer.The purpose of drill collars is to furnish weight to the bit.However,the size and length of drill collars have an effect on bit performance,hold deviation,and drill pipe service life.Hole openers under-reamers SPEA hole opener is a device used to enlarge the borehole during a well drilling operation.It can be positioned either above the drill bit or above a pilot run inside the existing borehole.An under-reamer is device designed to run in conjunction with a drill bit.It has cutters that can be expanded or contracted by mechanical or hydraulic means and used to enlarge or ream a borehole below the

Drilling Cost Reduction Through Use of Torque Controlling

Rotation of the bit is provided by the mud motor that converts the hydraulic energy of the mud pumped through it to mechanical energy in the form of torque and RPM output to the drill bit.The reactive torque produced by an aggressive FC bit can cause the drill string to twist unpredictably,resulting inDrill Collar Weight Calculation Methods - Drilling Manual Bit WeightA Key Factor in Drill String Design and Drill#0183;A key factor in common with the above referenced literature is that the bit-rock interaction is used to explain the cause of stick slip.A consequence of this is that the models are unable to explain the occurrence of stick-slip with the bit off bottom (where there is no bit-rock interaction). the drill-string design is a simple directional Down with the top hammer method -In top hammer drilling,the activity is concentrated at the top of the drill string,above the hole,as a hammer transmits cyclical shock waves to the drill bit by applying a percussive force on the drill rods or tubes (With DTH drills,the hammer is placed down-the-hole at the bit).
