Trapping Models for the Lower Silurian Medina Sandstone Group--A Comparison of Trapping Styles and Exploration Methodology for Both "Deep" and "Shallow" Medina Plays in the Appalachian Basin
ZAGORSKI, WILLIAM A., Mark Resources Corporation, Pittsburgh, PA
The Lower Silurian Medina Sandstone Group has been a major oil and gas producer in the Appalachian basin since the late 1800s and remains a primary objective in parts of New York, Ohio, and Pennsylvania. Although classified as a stratigraphic trap, production from the Medina is obtained from a wide variety of trapping conditions ranging from pure stratigraphic to structural stratigraphic in the shallower producing areas of the Medina to "deep basin" (i.e., Elmworth field, western Canada) trapping in the deeper producing regions of the Medina. Significantly different exploration and development strategies must be employed for optimum prospect development and maximum economic success ratios. Several producing areas of the Medina are presented to compare and contrast these various trappi g mechanisms together with suggested exploration models applicable to each trap type.
