USING RECENT ADVANCES IN 2D SEISMIC TECHNOLOGY AND SURFACE GEOCHEMISTRY TO ECONOMICALLY REDEVELOP A SHALLOW SHELF CARBONATE RESERVOIR: VERNON FIELD, ISABELLA COUNTY, MI.

In this reporting period two main accomplishments stand out. The Springdale task is in play in the northern Michigan Basin and the geochemical survey work over the Springdale prospect continued to progress. We still need to characterize the play in terms of the type of trap (basal reef diagenetic (?)) and its relation to the well documented pinnacle reef play. Also, we have become aware that Capac Field in the southern reef trend (Figure 1) is a possible analog to Springdale and so will be looking more closely at the literature on that field, particularly the work by Bowers (1987). Future work is directed toward further defining the Springdale project via more wells and examination and characterization of well cuttings. One to two more geochemical surveys are planned, one this spring and a final one in early fall. Based on current oil prices and Springdale production as of January 2005, an ROI, (defined as Total liquids revenue, $5.45m/DOE support, $1.45m) better than 3.75. This does not include gas revenues, which have not yet been calculated
