Oil Prospecting, Drilling and Extraction - By F.J.S Sur, E.M., Petroleum Geologist, Calgary, Canada
This document covers in detail the finding and production of oil and/or gas as practiced in the early 1900s. In this document, Sur has two chapters on drilling entitled; Drilling Methods and Drilling Don'ts. He described his reason for writing this book as follows;
"In the mining industry for the prospector, miner. geologist and engineer many books have been written. However, the prospector for oil, the driller and the general operator have never had any book giving and classified and systematic data. In this book I have, therefore, attempted to fulfill the requirements of the last mentioned."
His descriptions of percussion and rotary drilling methods are very complete, including graphics showing the different types of rigs in use and the areas of the world in which they are used. He makes no mention of a drilling fluid as such, only stating that water is circulated through the hole to remove the cuttings. Also, his list of equipment for a rotary rig makes no mention of mixing equipment or ways to hold and recirculate the drilling fluid (water).
He also stated that; "The rotary can be used in hard formations, an abrasive being used, but it is not so suitable as the percussion method in such cases." He did not metion the type of abrasive or how it was added to the system. Perhaps is was ciculated with thw water.
A diagram of the common Canadian combination percussion/rotary rig is shown here. Sur stated that; "The Canadian combination system is well adapted for hard formations, as it has auxillary attachemnt of poles by which the drill bit can be turned after each drop, thus cutting all parts of the surface equally.
