The objectives of this project are for a university–industry consortium to develop a comprehensive model for fractured carbonate reservoirs based on the "data cube" concept using the Michigan Basin as a prototype. This project will combine traditional historical data with 2D and 3D (?) seismic data as well as data from modern logging tools in a novel way to produce a new methodology for characterizing fractured reservoirs in carbonate rocks.

Advanced visualization software will be used to fuse the data and to image it on a variety of scales, ranging from basin-scale to well-scales.

Several new logging tools will be used in this study: (1) formation scanner logs will be used to delineate and quantify the fracture systems, and, (2) hydrocarbon logs, which are similar to traditional well logs except they are obtained by measuring hydrocarbon contents from fluid inclusions cuttings and core samples, will be used to identify and map diagenetic "halos".

In addition to the logging tools, traditional geologic and engineering data will be used to define and interpret the reservoirs. These include: formation tops and reported hydrocarbon shows obtained from driller’s reports, scout tickets, well logs and seismic data. Engineering data will include porosity, permeability, drill stem tests, initial production, API gravity and cumulative production histories.
