The Grosny district contains three oil fields: the old and new Grosny and the Vosnesenskaja fields. There were 450 producing wells in 1926. Fifteen of these flowed, by hydrostatic pressure, and yielded half of the total daily production. Twenty-two Miocene sands are encountered in drilling. Eight of these are oil sands. Water conditions have been given special study because of the several oil sands and intermediate water sands in the same well. Several sizes of casing are required to shut off the waters above each producing sand. In distinguishing the several waters and thus in correlating the sands, the characteristics of the waters were calculated after the method of Chase Palmer in reacting values and chemical properties. Tables and a chart are given, showing these com arative properties. The author concludes that edge water is encroaching and the future production should be small.
