Locating Under Water

摘要

For the purposes of this article, we will assume that the water crossing will take place using a walkover locating system.The alternative is to use a wireline steering tool, which typically involves the rental of specialized tooling and operating personnel.This is often cost-prohibitive, but it should be noted that some of the larger, more exacting crossings should only be attempted by using such a system. One of the most important tools that can be used in a water crossing is a good drill plan.The more information you have available prior to putting any rods in the ground, the greater the likelihood of success. Anything from commercially available drill planning software to a pencil and pad of paper will assist you in coming up with a proper drill plan.
