Three-dimensional trend mapping from wire-line logs
J.H. Doveton, Z. Ke-an
1985, Journal of the International Association for Mathematical Geology (17) 485
Mapping of lithofacies and porosities of stratigraphic units is complicated because these properties vary in three dimensions. The method of moments was proposed by Krumbein and Libby (1957) as a technique to aid in resolving this problem. Moments are easily computed from wireline logs and are simple statistics which summarize...

SOLVING THE TWO-DIMENSIONAL DIFFUSION FLOW MODEL.
T. V. Hromadka II, Chintu Lai
1985, Conference Paper
A simplification of the two-dimensional (2-D) continuity and momentum equations is the diffusion equation. To investigate its capability, the numerical model using the diffusion approach is applied to a hypothetical failure problem of a regional water reservoir. The model is based on an explicit, integrated finite-difference scheme, and the floodplain...
Conceptual model for origin of abnormally pressured gas accumulations in low-permeability reservoirs
B. E. Law, W. W. Dickinson
1985, American Association of Petroleum Geologists Bulletin (69) 1295-1304
The largest gas fields in the Rocky Mountain region occur in abnormally pressured reservoirs. These gas accumulations are different from more conventional gas accumulations in that they are commonly located in basin-center positions, they occur downdip from water-bearing rocks, and they are in overpressured or underpressured low-permeability reservoirs. We suggest...
