An AAPG member is asked to provide a study on fractures and seismicity in New York, putting him at the epicenter of the state's debate over the use of hydraulic fracturing.


Have an opinion about hydraulic fracturing? So does the person next to you, which is why Steve Leifer, this year’s speaker at the upcoming DEG annual luncheon, says to look at the big picture.  


The Marcellus Shale is a hot topic in the gas industry these days. Many have hopes that the gas found will assist in our energy needs until a better solution can be found.


It is approximately 80 miles between Titusville, Pa., and Fredonia, N.Y. – and while nobody is suggesting the rivalry between these two cities is on par with, say, the competition between the Red Sox and the Yankees, the origins of the petroleum industry is becoming a bone (a well?) of contention.

High resolution aeromagnetic surveys are being used with great success in Marcellus shale exploration.


When it comes to understanding the Marcellus Shale, it’s all about the fractures.

Explorer Historical Highlight


When New York began its first state geological survey in 1836, seep petroleum was used in small quantities primarily for medicinal purposes.

The attendee will gain a working knowledge concerning how faults and fractures develop and their terminology, methodologies utilized in collecting and analyzing fracture data, characteristics of faults and fractures that affect the sedimentary units (including black shales) in the northern Appalachian Basin of New York state, and tectonics that led to the formation of the structures in the northern Appalachian Basin and the adjacent Appalachian Orogen.
