Seite 7 - ... and concentration accompanied by noteworthy chemical changes. The field investigations were made during three summers in the Appalachian oil and gas region, b.ut the conclusions are of wide application. Many of the principles set forth by the authors are capable' of practical use, and the bulletin is of economic value to oil and gas operators, as well as of scientific interest. It contains numerous chemical analyses, geologic sections, and views of specimens collected from wells. The need of...

Seite 14 - Olentangy? shale. 80 Gray calcareous shale. Delaware limestone. Blue and gray limestone, becoming dolomitic in lower part. Contains a 30 to 50 foot bed of white quartz sandstone. 350 to 450 feet below top.
Seite 62 - The brine springs occur in large numbers and broil from fissures in the rocks. The water is strongly saline and gives very good salt on evaporation. In the center of the limestone region is a remarkable volcanic phenomenon. On approaching this from a distance one sees a dense cloud of steam that at intervals of several seconds rises and then disappears. This is accompanied by a roar like distant thunder. Nearer by one perceives a hemispherical mass about 16 feet in diameter, composed of black mud...
Seite 62 - ... the Island of Java salt is also made from brine springs, which flow from Miocene beds and usually contain iodine and bromide salts, as well as sodium chloride. Many of these brines contain petroleum and gas. The most striking are those of Grobogan. northeast of the city of Samarang, in north central Java. According to Karsten, the brines which are associated with mud volcanoes are in a limestone formation that forms a circular plain half a mile in extent.
Seite 31 - Physics and chemistry, vol. 1, 1884, p. 203. Salinity 3.301 to 3.737 per cent. B. Atlantic water, mean of 22 samples collected on a voyage from the Cape of Good Hope to England CJ 8.
Seite 91 - By ebullition and evaporation these solutions became concentrated until, saturation resulting, precipitation commenced, forming the necklike masses of salt, gypsum, and dolomite now encountered. With the cooling of the intrusive masses and the choking of the vents the process practically ceased. A period of subsidence followed, during which the coastal...
Seite 88 - F. (427° 482° C.) will consist of a rich gas amounting to 0.6 to 0.7 cubic foot per pound of coal, and a large yield of oil, or tar, comprising 10 to 12 per cent of the coal. This tar consists chiefly of paraffin hydrocarbons, is very low or possibly entirely devoid of benzene and naphthalene derivatives and practically devoid of free carbon. The gas will contain 6 to 7 per cent of unsaturated hydrocarbons and 20 to 25 per cent of ethane and its higher homologues, and consequently will have a high...

Seite 62 - The New Orleans Times-Democrat of Nov. 26, 1911, gives an account of a gas eruption in the sea off Erin Point, Trinidad, on Nov. 11, 1911, and says "The next day it was found that an island of 2^£ acres had been formed. A landing party found the place still warm, and by laying down boards were able to examine two cones, 12 to 15 ft. high, from which gas was escaping. The air was saturated with the odor of sulphur and oil.
