1-D Stratigraphic Analysis
There are two goals of 1-D analysis, which are somewhat related. The first goal is to use the available wellbore data to establish an initial cycle framework. To interpret a cycle framework, lithofacies data are almost always required, and cores represent the only true source of lithofacies data. The second goal of 1-D analysis is to quantify, integrate, and analyze the available wellbore data. Wireline logs, which represent the vast majority of the 1-D data in a reservoir, must be calibrated with quantified core data before being used for 2-D stratigraphic framework interpretation and in 3-D geologic models.

Sequence Stratigraphy and Characterization of Carbonate Reservoirs - Reservoir management is an important topic in the oil industry today. Conferences, forums, short courses, and technical papers, written and attended by engineers, geologists, geophysicists, petrophysicists, and managers discuss various aspects of reservoir management. A critical component of reservoir management is the accurate characterization of the hydrocarbon asset, called reservoir characterization. The topic of this course is the process of sequence-stratigraphic interpretation and characterization of carbonate reservoirs. Because of the overwhelming mass of information most reservoir geoscientists keep up with either some aspects of sequence-stratigraphy, or some aspects of reservoir characterization, but typically not both. The authors believe that the two disciplines are so intimately related that the sequence framework should be considered a critical piece of the integrated puzzle.
