Opening-mode veins in cores drilled from the mudrocks over- and underlying the major Silurian salt décollement in the Appalachian plateau (Tioga and Lawrence Counties, Pennsylvania), have mineralogic and isotopic compositions generally matching those of their host mudrocks, suggesting opening and filling amid little cross-stratal fluid motion.

In June, 2015, the Environmental Protection Agency released its long awaited draft assessment of the Potential Impacts on Hydraulic Fracturing for Oil and Gas on Drinking Resources. The major finding in the draft assessment is that there is no evidence that hydraulic fracturing has caused “widespread, systematic impacts on drinking water resources in the United States”.

This study demonstrates the application of aeromagnetic surveys for locating late 1800s-era oil and gas wells in Hillman State Park. The study area in southwestern Pennsylvania offered several unique challenges to locating legacy wells.

We herein document temporal changes in dissolved and gaseous methane concentrations in 12 domestic water wells completed in Late Devonian clastic aquifers in northeastern Pennsylvania over time periods from 0.2 to 2 yr. Wells with initial methane concentrations regarded as low (<5 mg/L), moderate (5–15 mg/L), and high (>15 mg/L) were all used in our study for comparative purposes.

We report the results of analysis and interpretation of 19,278 predrilling groundwater samples from water wells in the Appalachian Basin for dissolved methane collected from 2009 to 2012 (11,309 samples from northeastern Pennsylvania and 7969 samples from a western area that included north–central West Virginia, eastern Ohio, and southwestern Pennsylvania).

While 100 years is a great milestone, it is also true that our profession is younger than the other scientific professions that serve as cornerstones of our modern industrial society.

In the past eight months, our industry has continued to be challenged by low commodity prices resulting in difficult times for many geoscientists in our industry. To everyone who has been affected and to those of you who are concerned that you will be, remember to stay focused and be optimistic about your future.
