Trenton/Black RiverProduction Trends and History
• Geographic trends tied to geology
• Identifying fairways for future play development
• Identifying key wells
• Historical trends
• Resource assessment
Current Status
• Extensive dataset from OH,KY, NY
• Data from PA, WV limited
• Some mapping and graphing for data from OH, NY

Look for:
• Regional patterns that match geologic features
• Production “outliers” that do not fit regional trends

Estimating Ultimate Recovery from Annual-Cumulative Plots
• Easy to construct, but
• Assume no new (large) field discoveries and reserve growth
Future
• Decide on method: meeting among interested project members, USGS, and possibly industry expert
• Update data obtained from states
• Complete resource assessment
