Utica Drilling in Pennsylvania

In Pennsylvania, the vast majority of unconventional oil and gas activity is focused on the Marcellus Shale formation, a Devonian period deposit of black shale with a high hydrocarbon content, which requires horizontal drilling and large scale hydraulic fracturing to produce enough oil and gas to make the drilling economically viable.  This formation was created […]

Has radioactivity risk from oil and gas activity been underrated?

Reviewing a Pennsylvania TENORM Study By Juliana Henao, Communications Intern Technologically-enhanced, naturally-occurring radioactive materials, also known as TENORM, are produced when radionuclides deep in the earth are brought to the surface by human activity such as oil and gas drilling. The radioactive materials, which include uranium (U), thorium (th), potassium-40 (K-40) and their decay products, […]
