Geologic constraints on the upper limits of reserve growth
Richard G. Stanley
2001, Open-File Report 2001-265
For many oil and gas fields, estimates of ultimate recovery (the sum of cumulative production plus estimated reserves) tend to increase from one year to the next, and the gain is called reserve growth. Forecasts of reserve growth by the U.S. Geological Survey rely on statistical analyses of historical records...
Geologic map and digital database of the Conejo Well 7.5 minute quadrangle, Riverside County, southern California

Borehole geophysical data from Eastland Woolen Mill Superfund site, Corinna, Maine, March 1999
Bruce P. Hansen, William J. Nichols, Robert W. Dudley
2001, Open-File Report 2001-186
Borehole-geophysical data were collected in cooperation with the U.S. Environmental Protection Agency in seven bedrock wells at the Eastland Woolen Mill Superfund site, Penobscot County, Corinna, Maine, in March, 1999. The data were collected as part of a reconnaissance investigation to provide information needed to address concerns about the distribution and fate of contaminants in ground-water at...

Oil test wells can provide information on the depth, age, inclination, porosity, permeability, density, faulting, folding, and organic content of geologic formations mapped at the surface, or on units not recognized in surface outcrops. Formation density, as expressed in sonic and density logs commonly obtained when wells are drilled, has...
