“ The latter-day demands for the provision of lighter and yet lighter, as well as space-saving propelling machinery for submarines, airships, aeroplanes, motor-cars, etc., especially during the war, have enormously stimulated the development of the engine which consumes its own fuel, and which is known as the internal combustion engine. A very wide field has thus been opened out for the exercise of the engineer’s ingenuity, and he has availed himself to the full of the opportunities thus created, never failing to rise to the occasion when fresh demands have been made upon him. ”

“ At one time, the refiner had to consider the saleability of his refined products before he commenced to refine them, but to-day, with the perfect system which prevails for the handling of huge quantities of refined products, and the transporting of them to the most distant markets, the one desire of the refiner is, naturally, to secure from his treatment of the crude oil, as many refined products as possible, always keeping an eye on the production of the largest quantities of the higher priced products than upon those which are of low value. ”

“ We all know the remarkable progress which had been made in regard to the extension of the railway systems throughout the zones of battle, but it will surprise many to learn that it was when the rail-heads had been reached, and between there and the real battle front, that motor spirit had the realm of transport to itself. Tens of thousands of heavy motor vehicles took up the work of transport when it left the railway, and it was this service that was required to see not only that our millions of men daily received their food, but each and every sort of ammunition also. ”

“ Given the one allowance that oil fuel can be procured at anything approaching a reasonable figure—and there is no reason why, in normal times, this reasonable price should not be prevalent all over the world—then petroleum offers many advantages over its older competitor, coal. The ease with which large quantities can be handled, the simple method of operating anything which is fired by petroleum as fuel, and the fact that its heat-giving units are far higher than those of coal, will ever be the chief factors governing its popularity. ”

“ As already mentioned, the total oil transported to-day by the American pipe-line system exceeds half a million barrels daily. The lines themselves—all laid, of course, below ground—are so unobtrusive and do their work so quietly and unseen, that they attract no attention, and yet they are vastly important to not only the business of the States, but to those myriads of consumers abroad. ”

“ Vickers, in bringing their engine to its present state of perfection, have, perforce, had a varied experience with fuel oils—and a considerable one, too,—for they have experimented with oils from all the well-known producing fields, and find that, under their system, practically any fuel oil which can be made to flow may be utilized in their engines—a fact which, in its importance, speaks for itself. ”

“ The rig used with the Canadian system is not so powerful as that for the Pennsylvanian method, but the one great advantage of the Canadian system is that, for the drilling of shallow oil-wells, it could be operated by men of less experience. The success which has attended the operation of the pole system lies in the fact that although drilling by its means is very slow—for seldom is 250 feet per month exceeded—it is one of the best methods of drilling through complicated strata, and, in the hands of conscientious men, does highly satisfactory work. ”

“ There is a free field for Scottish enterprise in connection with the distillation of its oil-bearing shales. Nor is the region for development limited to its present area. Reports point to the fact that much area of commercial ground exists, not only on the eastern side of Scotland, but also in the north and north-west, while it is already an open secret that those responsible for the conduct of Government operations are viewing with favour even the liquid extraction of oil from certain areas not far distant from the zone of the present operations. ”

“ Incidentally, I may here say that when drilling for oil in Russia, one has to recollect several features which are not common to the development of other oil-fields. Bearing in mind the great depth to which wells have to be sunk to reach the prolific oil horizons in the majority of the fields in Russia, which necessitates starting the well with a very large diameter—frequently 30 inches—it will be easily appreciated that the loss of a hole in the course of drilling is a very expensive affair. The Russian free-fall system of boring necessitates patient and hard manual labour. ”

“ The headway which fuel oil has made during the past few years has been remarkable, though it is safe to say that its general use is still in its infancy. In no matter what capacity it has been tried as a heating or steam-raising agent, it has proved itself capable of withstanding most successfully the most stringent tests, and has convinced all who have given the question serious consideration that it holds numerous advantages over coal, yet has no drawbacks. ”

“ By its means we are now able to carefully study the nature of the ground at depths of 6,000 feet, and to extract from the deep lying strata a wealth of minerals; we are able, too, to transport thousands of tons of crude oil daily across thousands of miles of continent, while is it not the direct result of engineering science which allows over 15,000 tons of petroleum products to be carried across the oceans of the world in one vessel with the same ease that one would take a rowing boat from one side of a lake to another? ”

“ There is no doubt that a wonderful future awaits California in regard to its oil export trade. The Far East is largely drawing upon the State for crude oil for treatment in the Far Eastern refineries: the oil-burning vessels of the Pacific rely upon Californian fuel oil for their supplies, while the opening of the Panama Canal, and the establishment of oil storage depots there, has brought California within easy transport distance of the European markets. During the past few years several cargoes of Californian refined oil have, in fact, come upon the English market. ”

“ Experts have devoted considerable time and thought in an endeavour to arrive at a conclusion as to the length of time it will take for the withdrawal of practically the whole of the crude oil from the known deposits in the more developed 7 fields: their conclusions, however, are widely different, for while some assert that in the United States, for instance, the known fields will cease to be commercially productive within forty years, others there are who declare that centuries must elapse before the question of a failing supply need call for serious consideration. ”

“ In many of the fields, explosives are used to promote the flow of oil, and when the well “comes in” to production, the ordinary methods of bailing or pumping are resorted to. Compressed air is also used for bringing about and sustaining production. The quantity of air and the periods of admission naturally vary with the diameters of the wells, the amount of gas present, the level of the liquid, etc., which latter also determines the pressure of air necessary. ”

“ A wealth of inventive effort has been bestowed in the perfection of the burners employed to consume fuel oil. Leaving aside for the moment the principles governing the use of oil in the internal combustion engines of the Diesel or semi-Diesel type, fuel oil used for the production of power is introduced into the furnace in the form of a spray, this being accomplished by atomizing the oil in its passage through a specially designed burner. ”

“ The crude oil of Trinidad is of both the light and the heavy grades, the former showing remarkable percentages of motor spirit, while the latter is used not only as fuel oil but also for the treatment of roads so as to render them dustless. It is in Trinidad that there is the famous pitch lake, from which for many years large quantities of asphalt have been removed and exported for a variety of purposes. Trinidad asphalt, in fact, is well known all over the world. ”

“ In our industrial life of to-day there are a vast number of instances where fuel oil is rapidly displacing coal: the oil-fired furnace has been brought to a stage of 85 86 perfection, and is being extensively and increasingly employed both in this country and abroad in regard to metallurgical and industrial processes. Without going into detail respecting the numerous spheres in which the new fuel finds profitable employment it is safe to say that these are being extended every year. ”

“ It is, in fact, impossible to over-estimate the importance of this up-to-date system of oil transportation in the United States as it exists to-day. To show the impossibility of conducting the present-day American petroleum industry without the use of pipe-lines, let me give a few facts. The large oil-tank cars, which are not unusual sights on our railways, hold, at the maximum, about 25 tons of oil. Excluding California altogether from these illustrations, the half-a-million barrels of oil which are transported daily in the States by pipe-lines would fill over 2,500 tank cars. ”

“ Ever since the petroleum industry assumed proportions of international magnitude, and we became more or less (I should have said more than less) dependent upon our necessities being met by petroleum and its products, private enterprise has always kept us well supplied. But the Anglo-Persian Oil Company has made immense headway since the Government took an interest in its operations, and its appearance on the English market as a refiner of Persian crude oil and a distributor of the products thereof, is but a reflection of the prolific nature of the vast fields in Persia which it possesses. ”

“ To-day, in every branch of the industry associated with petroleum—whether it be 42 in producing the crude oil, in transporting it, or in refining Nature’s product into those numerous commodities which are part and parcel of everyday life—the engineering aspect is one of very great importance. In fact, throughout the petroleum industry, engineering science is the Alpha and Omega. ”

“ The ever-expanding uses of petroleum, which in their train have called for a continually increasing demand for crude oil, have given an impetus to the search for commercially productive oil-fields, which, in mining history, has no parallel. On the one hand, we have those important oil-producing regions which embrace enormous regions of the United States, Mexico, Russia, Roumania, the Dutch Indies, India, and Galicia ”

“ The natural exhaustion of oil-wells can obviously have no remedy, but areas conveying that impression can often be revived by methods, the study of which is being carefully continued. As I write, I find that the officials of the United States Bureau of Mines, who have been studying this question of exhaustion, have arrived at the conclusion that from 20 to as much as 90 per cent. of the crude oil remains in the strata tapped by the well, even when it is abandoned as no longer capable of profitable production. ”
