By long experience many drillers learn to distinguish, generally quite correctly, the three principal classes of sediments in which most of their work is done, such as shale or clay, sandstone and limestone. The most experienced drillers in any locality have, also, expert knowledge of what we may call the key rocks of the field in which they work. They know the rocks that. determine the depth at which casing is to be set, or the depth at which the tests for oil or gas must be made. This knowledge of rocks is mostly taught from mouth to mouth, by the head driller to his helpers, entirely without any other guidance than the limited experience of each driller. No aid, so far as I know, has ever been prepared by geologists to help drillers in procuring the information both are eagerly seeking. With the extension of drilling operations to regions of widely different geological formations and conditions, it has become a matter of some urgency that drillers logs be made with greater accuracy and uniformity than before. The only way to encourage improvement in this direction is to place in the hands of the men who make the logs, what aid they need. By the use of a few very simple devices, available to all, great improvements in results can be attained without the least loss of time.. The present paper is an attempt to present some information, in compact form, that will aid practical and intelligent men to correctly identify materials explored in drilling for oil, gas, or water. It will be found that much of the information here set forth consists of elementary methods and facts drawn from mineralogy and geology. Most drillers are eager to acquire all knowledge they can in these sciences.
