The Ordovician-aged Point Pleasant Formation is an economically important unconventional oil and gas play in the Appalachian Basin, in particular Ohio, western Pennsylvanian and West Virginia. The Point Pleasant Formation is known to have overpressured pore fluids, that is, pore pressure above hydrostatic conditions. Overpressure is an important rock property to constrain because it exerts a strong control on the mechanical stability of boreholes, the response of the formation to hydraulic fracture stimulation, and volumetric flow rates of produced fluids. However, what is not well known is the spatial distribution, magnitude, and controls on the overpressure within the Point Pleasant Formation. In this study, pore pressure in the Point Pleasant Formation is estimated based on sonic velocity geophysical logs measured in 33 wells as well as mudweight data from 23 wells. From this analysis, a map of overpressure in the Point Pleasant identifies a large area of overpressure centered in southeastern Ohio primarily within the counties of Noble, Monroe, and Washington . This overpressure map may facilitate target selection, safer drilling, and more successful well completions. Areas of significant overpressure have also been linked to enhanced risks of induced seismic events, thus the overpressure map may also indicate areas that have higher probability to trigger induced seismic events during hydraulic fracturing or waste water disposal.
