Drawworks Brake System can be divided into: MAIN BRAKES (STATIONARY BRAKES) The main brake of a drilling rig is the mechanical band brake or the
There are two essentially different types of inclination-only tools in current use. The simple MD TOTCO deviation survey tool (single shot) so, called after its
Halliburton’s Geopilot RSS rotary steerable system also uses “point the bit” technology. The design concept involves the deflection of a flexible shaft between the drilling
Schlumberger provides three types of PowerDrive RSS or rotary steerable systems with different principles of operation, and different generations of tools exist within some of
The Baker Hughes AutoTrak RSS (Rotary Steerable) uses a non-rotating sleeve close to the drilling bit. The sleeve utilizes three independent hydraulic and control systems.
Formation pore pressure is the pressure exerted by the formation fluids on the walls of the rock pores. The pore pressure supports part of the
The only way to obtain information, before well drilling, on the nature and characteristics of the subsurface, including the pore pressure prediction, is through geophysical
Background gas enters the mud circulating system as the formation is drilled by the drilling bit and usually maintains a steady but low level. Additionally,
D is an exponent which, relating drilling penetration rate to weight on bit per unit hole diameter, measures the formation’s ” drillability “. There were
Jetting (or badgering) technique is used in directional wells to deviate wellbores in the soft formation. The technique was developed in the mid-1950s and superseded
