If you are the kind of drilling contractor who could always rely on a steady supply of work from trusted clients, you may suddenly find yourself having to bid jobs you used to get selected for, and re-bid some of those you think you won.
Contractors need to seek out workers who have some idea about the kinds of work they will be doing, who are trainable, have good communications skills so they can talk to customers and contractors, and be able to write legible reports that wil be acceptable if they are ever used as evidence in a court case.
