What is drilling torque?

Drilling Torque is the measured torque while drilling under normal hole conditions. Increases over the drilling torque are referred to as Incremental Torque. The upper limit of the measured weight is called the Maximum Allowable Measured Weight. It is determined by the minimum of:

What is torque and drag in Drilling Optimization?

Torque and Drag In Drilling Optimization). Rotating Weight is measured while rotating off the bottom without reciprocating. The down Drag is the difference between the down weight and rotating weight, whilst the difference between the up weight and rotating weight is called the Up Drag.

Does borehole instability affect the depth resolution of cuttings?

The effects of high penetration rates and borehole instability on the depth resolution of cuttings should be considered when concluding cuttings. The impact of the over-gauge holes on lag time and depth should be considered if there is any potential for hole enlargement.

What is up weight & down weight in drilling?

The converse is Up Weight, i.e., when moving the drill string upwards. Every driller knows that the up weight reduces and the down weight increases when he starts rotating the string. Torque and Drag In Drilling Optimization). Rotating Weight is measured while rotating off the bottom without reciprocating.

How to optimize a drilling bit?

Keep the drilling parameter “applied weight on drilling bit” smooth once it has been optimized. Feed weight continuously to the bit using the Driller’s electric brake (Elmago, Baylor, etc) and avoid “slack-off / drill-off” – this can contribute to damaging torsional vibrations.
