Unraveling the stratigraphy of the Oriskany Sandstone: A necessity ...

5.7 and 5.2%, respectively. Intergranular porosity
and, to a lesser extent, dissolution porosity are observed
in the Dop. Secondary porosity from dissolution
of carbonate grains and cement controls porosity
in the Doc.
2. Well data from the Dho play show high fracture
porosity, but favorable reservoir characteristics are
not observed elsewhere in the play, and the structural
complexity of the Oriskany will complicate injection
into the unit at this site. Additional data from
the Dho play are necessary before recommendations
regarding sequestration potential can be made for
this play.
3. Sequestration of CO2 is not recommended for the
Dos play. The tightest Oriskany Sandstone occurs
in this play, with calculated and measured porosities
of less than 2% from Pennsylvania sample locations.
Porosity calculated from geophysical logs in New
York averaged 3.2%.
4. Although the available porosity and permeability
data presented herein provide some insight into potential
sequestration sweet spots, they also show the
importance of collecting new data for each individual
site considered for geologic sequestration of CO2.
Geophysical log data are the most readily available
tools for geologists in determining reservoir porosity
and permeability, but the use of core, sample, and
other data is also integral to understanding the structural
setting and diagenetic history of reservoir rocks
such as the Oriskany Sandstone.
