...Beginning in the icebound Arctic, they take the armchair beachcomber on a scenic tour down the East Coast, past Cape Cod and the islands, along the perilous shoals of the Carolinas, through the lost waterways of the Everglades and Louisiana bayous, then up the West Coast from the desert sands of Baja California, past the cypresses of Monterey and the great coastal forests of the Pacific Northwest to the fog-shrouded Aleutians. Readers may not finish the tour with sand in their shoes, but most will close this lyrical volume yearning for the smell of salt...
...paycheck from an energy company. A recent report to the Governor of Louisiana estimated that 85% of the state's potential oil-and gas-producing deposits have not yet been drilled, but most of the unexplored reserves are very deep and difficult to find, as in the Tuscaloosa Sand. There the wells are four times as deep as the average U.S. well. Drilling one costs about $5 million if it is a producer, almost as much if it is a dry hole-and dry holes outnumber the producers 3 or 4 to 1. Louisiana officials argue that the heavy...
While the search for gas in the Tuscaloosa Sand is being conducted mostly by private business, the U.S. Department of Energy is providing funds to assemble information on the Gulf Coast's geopressured zones. In theory, the water from these zones, emerging at a wellhead pressure of 6,000 lbs. per sq. in. and a temperature much above boiling, could spin turbines and yield heat for such purposes as oil refining, food processing and rice drying. The gas that is dissolved underground in the hot water fizzes out of solution at atmospheric pressure to be captured for fuel...
Other sticky problems will challenge the engineers and designers. Sand will probably have to be screened out by costly stainless-steel filters at the bottom of each well. The corrosive quality and high temperature and pressure of the brine will demand specially designed piping, valves and moving machinery. The exhaust water will have to be pumped back into the earth to avoid turning the area into a swamp. The economics will look more encouraging, however, if Congress adopts a provision now in a pending tax bill that will allow a tax credit...
...anthropology. Richard E Leakey, renowned paleoanthropologist (he digs up skulls and other bone fragments in Africa) confronts the problem of envisioning human ancestors that lived over 2 million years ago and have left us only a few clues in the form of bone splinters now half covered by desert sand...
