  • Stratigraphic correlation of well logs: an automated approach in Geomathematical and petrophysical studies in Sedimentology. An international Symposium.
  • The stratigraphic behaviour of chemical elements (CaC0, Mg, Sr, Fe, Mn, Cu, Ni, Cr and V) in the Niobrara Chalk, a sequence of rythmically deposited carbonate sediments, is characterized by dilution cycles of terrigeneous clay and volcanic ash
  • Accurate definition of discrete correlative intervals within long sequences will perhaps be the most difficult problem. Accurate identification of significant gaps or breaks in a stratigraphic sequence is troublesome and solution of the correlation
  • In the eastern Gulf, the upper sedimentary section on seismic profiles can be subdivided into three seismic-stratigraphic units. Computer generated isopach maps of each unit permit study of the Neogene-Quaternary regional depositional patterns
  • Regression and trend surface analyses were used to facilitate interpretation of geological history of a stratigraphic interval of the Aratu Unit, Reconcavo Series (Lower Cretaceous) in the Reconcavo Basin, Bahia State, Brazil. The relation between
  • In stratigraphical analysis polynomial trend surfaces may be used to approximate structural surfaces or intervals betwween these surfaces or other variables of interest. Using the derived algorithm it is possible to compute rapidly the exact volume
