Stratigraphic formation
formation in the subsurface. These elevation measurements provide the third dimension for characterizing the depth or elevation of a reservoir on an otherwise two-dimensional map. Enverus DrillingInfo Inc. provides these stratigraphic picks, or formation depths, based on well log interpretation (well observations).A collaboration between the CGS and the Denver Museum of Nature & Science (DMNS) generated a new stratigraphic chart for the state of Colorado. This color chart was designed from the ground up to illustrate the Proterozoic to Holocene stratigraphy that spans the state’s many sedimentary basins.A collaborative effort led by Robert Raynolds and …

Within the Ashville Formation, only the Newcastle Member consists predominantly of sandstone. In northernmost British Columbia, correlative strata are the upper Lepine, Sikanni, Sully, Dunvegan and lower Kotaneelee formations. Stratigraphic History Basal Contact and Units. The base of the Colorado Group is represented by a basin-wide unconformity.The Yan'an Formation of the Ordos Basin in North China is among the largest and most extensively studied Jurassic coal reservoirs in the world. The lacustrine Yan'an Formation was investigated near Dongsheng (Ordos Basin, China) in its sequence-stratigraphic context, to understand the factors that controlled the peat accumulation and the cyclicity in the coal-bearing strata. Nine facies ...Chemostratigraphy is the study of the inorganic/organic chemical variations within the sedimentary sequences, either based on the elemental or isotopic composition of the rock. It provides a useful tool for unconventional resource exploration and development. The chemistry of a rock varies with its mineral composition (Fig. 2).Rock chemistry is relatively easy to measure, so quantifiably, the ...produce a composite stratigraphic section for the Green River Formation in the south-central part of the Uinta basin.
