Excerpt from Drill Work, Methods and Costs: A Practical Treatise Covering the Methods Used in Drilling Wells With Cable and Hollow Rod Tools In compiling the instructions, the object kept in view was to tell not only how a thing should be done, but also why it should be done as advised, thus explaining the principles lying back of the work. It is to be expected that some of the methods advocated will not meet with the approval of all drill men, but inasmuch as the reader will find reasons accompanying each method advocated, he is in a position to vary the methods as soon as he finds that his drilling conditions are such that other reasons outweigh the ones given. It must be borne in mind, however, that in drill work a mere opinion is not a reason unless it has been formed after careful consideration and ample experience. It is very likely that after a first reading of the instructions a beginner will get the impression that there is considerable risk connected with drill work, due to frequent references made regarding troubles which mightarise unless certain precautions are taken. While it is not the aim of the author to menace the beginner with disaster and while it is very likely that fishing jobs will be few and far between, if ordinary precautions are taken, still it will be found that in the large majority of cases the most prosperous drill men are those who pay the closest attention to the seemingly little things, and thus the reader's attention has been directed not only to the manner in which drilling tools should be handled, but also, in many cases to the troubles which can arise unless the tools are operated as instructed. It will also be noted that considerable space has been devoted to the handling of fishing jobs and other unusual conditions and while it is very probable that a drill man engaged in shallow, water-well work will have need for but a few of these. Instructions, still the author would urge a care ful reading of this section as the driller who has a full understanding of the troubles which can arise is very apt to use the necessary precautions to pre vent their occurrence.

Excerpt: ...repeatedly urged that no unnecessary chances be taken, still there are certain localities where it is necessary for some chances to be taken in order to get a well down at an economical rate. When a driller knows beforehand that he will have dangerous drilling, he should be provided with fishing tools for taking care of the kind of jobs that are liable to arise in that particular locality. As a rule it will not require a very extensive fishing equipment as it is only necessary to provide tools for taking care of the fishing troubles which the peculiar formations of that particular section may cause. If you are operating constantly in such a territory, you should purchase the fishing tools, but if you are going into the territory simply to drill a well or two, it will probably be cheaper for you to rent the tools from your drill manufacturer. When the tools become fastened in a caving hole, no time should be lost in going after them as each minute lost is liable to add to the difficulty of recovering them. The bumper should first be run in an effort to start the jars. If the jars can be loosened, the tools can usually be recovered. If you are unable to get the jars to work and the hole continues to cave, then the bumper should be removed and the cable cut off at top of rope socket. In cutting the cable, the horseshoe knife shown on page 159, should be used and should be operated on the end of a line of pipe instead of on sand line as described on page 160, owing to the fact that if operated on the end of sand line, the caving of the hole may result in fastening the knife. If pipe is used, the knife can be jarred out even if the hole does cave quite a bit. In cutting off the rope, it should be cut right at the top of rope socket or not...
