The Oil Fields of Mexico (9643cb83-7042-4132-b978-d68a03f18e57)

Discussion of the paper of EZEQUIEL ORDOÑEZ, presented at the Pittsburgh meeting, October, 19.14, and printed in Bulletin No. 94, October, 1914, pp. 2531 to 2536. DAVID T. DAY, Washington, D. C.-Dr. Ordoñez is really the pioneer in the study of the occurrence of Mexican oil. His studies came at such an early time as to prove really prophetic. He was successful in pointing out the relationship of these oil deposits to the volcanic teeth which are so very characteristic as a geological feature in the coastal plain of Mexico. At that time only the first wells around Ebano had been drilled, and drilled under the direction of Dr. Ordoñez himself. Only these Ebano wells were available for a real study of the condition of the occurrence of oil, the other large gushers not then being known. From that time on, the study of the geology of the country has, in large measure, been able to keep up with the oil development. As usual, a great deal of haphazard work in the exploration of the oil fields has been carried on. The results have been good, bad, and indifferent. We know a great deal more about the distribution of oil in Mexico than we do about the geology of it. Two ideas have become prevalent in regard to the Mexican oil, due to the peculiar development there: (1) That oil is omnipresent over a tremendous area bounded by De Soto La Marina, in the province of Tamaulipas, on the north, to south of Tuxpam in Veracruz; and (2) that there are very few spots in all this region which have rich gushers. The truth is somewhere between the two. The amount of land taken up, chiefly by three or four large companies, is extremely great, and covers all the possible chances. The idea that oil is going to be discovered in a large percentage of the land taken up by the oil companies, seems to me entirely unjustified. The amount of oil that will be produced from comparatively small spots here and there over that territory and other territory, undoubtedly will be very great. I do not think there is any hope of multiplying the capacity of these large gushers by the area of that part of Mexico in which they are contained, as a, large number of promoters are inclined to do.
