Abstract:
A method and system for automatically controlling drilling weight-on-bit for using a drill-string to drill along a wellbore is described.

Claim (Index 21):
The system of  claim 17 , wherein if the drill-string is under a compression force F cr , F cr \u2265 ( 4 \ue89e 2 - 2 ) \ue89e ( EI \ue89e \ue89e \u03b2 \ue89e \ue89e w \ue89e sin \ue89e \ue89e \u03b8 r ) 1 \ue89e / \ue89e 2 ( 2 ) where E is the Young's modulus, I is the polar moment, is the buoyancy factor, w is the linear density, is the inclination of the well, and r is the radius of the wellbore, then the surface tension data is calibrated by the following equation: F T k = - 2 \ue89e ( EI \ue89e \ue89e \u03b2 \ue89e \ue89e w \ue89e sin \ue89e \ue89e \u03b8 r ) 1 \ue89e / \ue89e 2 \ue89e tan \ue8a0 ( \u03bc k \ue89e \u0394 \ue89e \ue89e L \ue8a0 [ r \ue89e \ue89e \u03b2 \ue89e \ue89e w \ue89e \ue89e sin \ue89e \ue89e \u03b8 4 \ue89e EI ] 1 2 - tan - 1 \ue89e { F T k - 1 \ue8a0 [ r 4 \ue89e EI \ue89e \ue89e \u03b2 \ue89e \ue89e w \ue89e \ue89e sin \ue89e \ue89e \u03b8 ] 1 \ue89e / \ue89e 2 } ) ( 3 ) where F T k  is the tension at the top of the kth string component, \u03bc k  is the effective friction coefficient of the k th  drill-string segment, and \u0394L is the change of length for that joint.
