ABSTRACT: Michigan Antrim Tracking System (MATS)

Peter A. Roberts, Stephen Oliver

Although drilling activity in the Antrim shale has increased from 15 wells in 1985 to over 400 wells in 1989, little geologic work has been performed to site these wells, or to understand the geologic controls on gas production. The Gas Research Institute has initiated a field-based research project, parts of which entail gathering and analyzing single well data to improve understanding of this resource.

To manage and monitor the potentially large amount of spatial data on these wells, ICF Resources has designed the Michigan Antrim Tracking System (MATS). MATS is a sophisticated stand-alone IBM-PC based system that is user-friendly and menu driven. The system provides a variety of reports for statistical purposes and is interfaced with computer mapping and Graphic Information Systems (GIS).

Using computer mapping software and the GIS system Arc/Info, a variety of maps highlighting different trends in the Antrim shale can be generated. These include maps showing distribution of initial water and gas production, structure and isopach maps on the Antrim, and maps based on other available data such as proppant loads, porosity, and flowing bottomhole pressures.

The statistical reports generated by MATS together with the collection of maps and current geologic and geophysical work can provide the basis for establishing geologic and production trends within this active but little researched gas play. In this way, insight can be made toward improving reservoir definition and gas production potential.
