Radioactive Well Logging
… properties of many substances make radioactivity well logging possible. The Gamma Ray Curve records natural radiation; the Neutron Curve records induced radiation. In general the Gamma Ray Curve records formation types while the Neutron Curve records fluid content of the rocks. The Radioactivity …

Reservoir characterization using seismic reflectivity and attributes
… surface seismic data complemented by available well logs. To accomplish this a two-step procedure is followed. First, reflectivity and acoustic impedance profiles are obtained from the inversion of post-stack seismic data. Second, a multi-attribute analysis, calibrated using well logs, is used …

Reservoir characterization using intelligent seismic inversion
… is used as an intermediate step between the well logs and the surface seismic. Generalized regression neural network (GRNN) is used to build two correlation models between; (1) Surface seismic and VSP, (2) VSP and well logs both using synthetic seismic data, and real data taken from the …

Characterization of Lower Permian Carbonate Subaqueous Gravity Flows in Crockett County, Texas
… ramp slopes act as a link to relatively well-studied platform and basin depositional environments. In the southern Midland Basin, the key to understanding the relationship between these environments lies in the allochthonous gravity flow sediments found on the slope. Here, a succession of …

The Occurrence of the Greta Sandstone, Frio Formation (Late Oligocene), Texas Gulf Coastal Plain
… deposits. The interval is easily recognizable in well logs based on its strong SP and Gamma-ray responses. The depositional limits of the Greta sandstone within the Greta/Carancahua barrier/strandplain system has been mapped based on correlation of several thousand well logs throughout the south …
