Is a pilot hole required to drive oil-field pipe?

No, a pilot hole is not required. In rocky ground we will sometimes drill a small-diameter probe hole (13/4-inch diameter) to determine if we will encounter a rock with the pipe. If we run into rock, then we move a few inches and probe again to see if we will miss the rock. Probing ensures clear passage and avoids starting to drive a pipe and then having to pull the pipe if it solidly hits a rock.
