Seneca Resources continuously monitors and reports on specific types of air emissions that are relevant to its business operations as required by state or federal regulations. The company regularly reviews its emissions management and monitoring protocol.
|The General Electric Jenbacher J320 is powered by natural gas and is key to providing electrical power to Seneca drilling operations.
In 2014, the company began formalizing a greenhouse gas (GHG) management program, with an ultimate goal of reducing Environmental Protection Agency (EPA) reportable GHG emissions, and improving air quality associated with field operations.
Seneca also participates in the EPA's Gas Star Program. The program, of which the company is a voluntary partner, includes a commitment to implementing best management practices for reducing methane emissions - often beyond regulatory requirements.
In October 2011, Seneca began utilizing General Electric's 1.01-megawatt (MW), Jenbacher J320 turbocharged EPA mobile certified natural gas engines to provide all electrical power needed to support drilling rig operations. These were the first dedicated 100 percent natural gas (LNG)-fueled drilling rigs in Pennsylvania's Marcellus shale region. Seneca also utilizes field gas when it is available.
In addition, the company began updating its vehicle fleet in its East Division in 2013, and replaced older vehicles with dual-fuel vehicles that run on both natural gas and gasoline. As of summer 2016, more than 45% of Seneca's fleet vehicles can run on natural gas.
Seneca strives to utilize green completions by flowing gas directly into production upon well completion whenever possible. This process minimizes venting of volatile organic compounds (VOCs) and methane during well completion. In 2016, an estimated more than 95% of Seneca's wells will utilize green completions.
Some additional elements of Seneca's emission control program include:
- State of the art well surveillance, monitoring and reporting.
- Utilization of automated valves / artificial lift (gas lift, plunger lift and vapor recovery systems, Upstream/Downstream Flow/Pressure Control).
- Ultrasonic and infrared methane detection devices.
- Operator well status updates (Pumpers can enter changes made to any well as the change is being made via web, mobile apps or handheld data collectors).
- Proprietary wireless communications network provides fast access to data and real-time reporting.
- Extensive programs to conduct Leak Detection and Repair Surveys, and Mechanical Integrity Assessments of compressor sites, wellheads, tank batteries, production equipment and associated piping.
