Frac and Produced Water Treatment
Frac and produced waters from the Marcellus and Utica Shale plays continue to be a hot topic throughout the Oil & Gas industry as well as with citizens throughout the Tri-state area. As recently as May 2013, news from Ohio suggests law makers are considering banning frac and produced waters into deep injection wells. While [...]
Up Front Engineering is the Key to Successfully Managing Capital Projects
The end of the fiscal year is quickly approaching and capital budget plans for next year are due. Operations, Engineering and Maintenance have ideas of where funds can best be utilized, but day-to-day requirements only allow them to develop rough cost numbers and schedule durations based on “similar” projects from years ago. The project gets [...]
Marcellus Natural Gas Liquids
In the Western half of the Marcellus Shale Play, more than just methane flows from gas wells. In this region, hydrocarbons known as “natural gas liquids” (NGLs), are also present with the methane extracted from these wells. If harvested, these NGLs can be very valuable co-products of natural gas processing. The price of NGLs typically [...]
Update Regarding PADEP Proposed Treatment Standards for High TDS Wastewaters
The following is an update concerning what framework the PA Department of Environmental Protection (PADEP) will propose in a revised TDS regulatory approach. PADEP had proposed a uniform 500 mg/l TDS effluent limit on all new or increased “High-TDS” dischargers. In response to a request for public comments, PADEP received the message that the 500 [...]
What Is Next For Frac Water Treatment
The management of Frac water from development of Marcellus shale wells has been subject to increasing scrutiny. The deeper Utica shale formation is as promising as the Marcellus formation, and will probably have similar management issues. Concerns about frac water include: Nature of constituents added for fracing Salinity of the frac water and impact of [...]
PADEP to Adopt New Treatment Standards for High TDS Wastewaters
In an effort primarily to address the potential impacts from the development of the Marcellus Shale reserves, the Pennsylvania Department of Environmental Protection (“PADEP”) has announced its intention to adopt new treatment requirements and water quality standards to control total dissolved solids, sulfates and chlorides. According to PADEP, the justification for its new permitting strategy [...]
Marcellus Shale Play – Water Treatment Options Worth Considering
Centered in western Pennsylvania, the Marcellus stretches over 650 miles of the Appalachian Basin from West Virginia to the state of New York. Marcellus has been estimated to contain anywhere from 58 trillion to 500 trillion cubic feet of gas. A member of the Devonian black shales, Marcellus is categorized as a dual porosity reservoir, [...]
