Course Objectives and Items You will Learn About:

• The geology and occurrence of hydrocarbon-bearing terrestrial and shallow marine sandstone reservoirs in a broad variety of depositional settings.
• Current ideas on how sands are transported and deposited in a broad spectrum of depositional environments.
• The utility of systems tracts in terrestrial and marine environmental recognition and reservoir, source, and seal predictions.
• The role and limitations of seismic data in environmental recognition.

Overview:

The course is primarily a workshop, focusing on elusive terrestrial and shallow marine reservoirs using a combination of sequence stratigraphy seismic facies analysis and geologic concepts. The environments covered include eolian, alluvial, fluvial, lacustrine, deltaic, coastal, and open shelf environments. For each environment, slides and figures illustrate ideas about modern stratigraphy and sedimentology. Case histories of hydrocarbon accumulations and trapping configurations are presented. Then participants utilize a grid of seismic data to effect a seismic sequence and facies analysis of the environment and to predict drilling locations.

For each problem, source, seal, and reservoirs are predicted; available wells are used to evaluate the predictions. The terrestrial problem focuses on a Permian reservoir in the North Sea. The alluvial fan delta involves mapping a Cretaceous wedge derived from the Caledonian basement in northwestern Europe. The focus of the fluvial occurrence is in the Cretaceous of the Gulf Coast. A broad spectrum of deltas is prospected by different teams (e.g. Gulf of Mexico, northwestern Europe, the Nile, Gabon, Morocco, or Mozambique). Shelf sands are prospected through systems tract analysis in the Gulf of Mexico and Norway.
