Q
  1. What is NOT an advantage of the top drive compared to the rotary table?

a) It enables complete 90’ stands of pipe to be added to the string rather than the conventional 30’ singles. This saves rig time since 2 out of every 3 connections are eliminated
b) Their rental rates are much cheaper compared to rigs with conventional rotary table systems
c) It saves rig time
d) It has the ability to rotate the drill pipe while tripping into or out of the wellbore to avoid Stuck Pipe during tripping operations

A

b) Their rental rates are much cheaper compared to rigs with conventional rotary table systems
