Drill String Design As inclination angle increases in a directional or horizontal well, the borehole walls support more of the drill string weight. This contact, along with the capstan effect (the normal force caused by the deformation of an axially loaded member about some obstacle), results in frictional forces that oppose the …

The tools used to quantitatively evaluate flow volumes downhole are the radioactive tracer/gamma ray and the flowmeter. The radioactive techniques are used mostly ...
