...Arno Carl Fieldner of the U. S. Bureau of Mines raised the old bugaboo about the imminent exhaustion of oil & gas. There was enough coal, he said, to last 2,100 years. But the known reserves of natural gas were 30 to 40 trillion cu. ft., of oil 13 billion barrels. At the present rate of consumption the petroleum would be gone in 13 years-but Dr. Fieldner predicted that discoveries of new pools and more efficient production techniques would stretch out the supply for a century. Unless "greater social control" was forthcoming, known supplies of gas would vanish...

...impressively successful technique for hiking oil production is treatment with acid. In certain limestone formations, acid treatment not only "brings in" or increases production on new wells but rejuvenates old ones. Object of pumping in acid is to eat out new channels in the limestone. Hydrochloric acid is used, chemically inhibited so that it will not attack steel casing or tubing. The acid doctor pulls out the tubing and pumping equipment, runs the tubing back with a packer 15 ft. above the bottom so acid will not run up the hole, squirts...

...limestone began to look promising, Vandergrift decided to confine his practice to the limestone formations of West Virginia, moved to Spencer, arriving there in 1934 with a few gallons of acid, a few dollars, no orders, much confidence.

...Vandergrift has had even better luck with gas wells than with oil. It is not unusual for a Vandergrifted gas formation to increase its yield by 1,000% to 7,000%. Few weeks ago a gas well in Boone County jumped after treatment from 800,000 cu. ft. daily to 3,600,000 cu. ft. Last month Vandergrift branched out into Ohio and Kentucky, did the biggest month's business since he started. Because he knows his trade from the ground down and is willing to go out on a case at any hour, in any season, over...
