Production

Production

Oil and gas production takes place after drilling and hydraulic fracturing.

Equipment needed to produce a well generally includes a four- to six-foot well-head, a production unit, a tank and pipeline that connects to a gathering pipeline that will transport the oil or gas to downstream distribution networks.

A natural gas well such as those in Pennsylvania can produce gas for up to four decades. Some of our oil wells in California have been producing oil for 100 years.

In addition to our production equipment being monitored in real time by cutting-edge automation technologies, our employees and contractors regularly perform on-site inspections of well sites.

GPUs

Bulk Gas Production Unit

Historically, Seneca Resources installed a dedicated gas processing unit (GPU) for each gas well on a pad location. Recently, bulk GPUs have been installed at a number of these locations. This advancement in production technology allows for the flow of up to eight wells through a single bulk GPU. This maximizes the size of area that can be reclaimed, which benefits the environment. Bulk GPUs improve production efficiency and reduce maintenance costs. They also require fewer equipment connections and components (particularly pneumatic controllers), which helps to reduce air emissions.

Gas Detection

We utilize gas detection equipment in our GPUs to identify gas leaks quickly and safely. Ultrasonic meters are also installed, which are capable of sensing gas leaks on flow lines/sales lines by listening for high-pitched leaks. If a leak is detected, the pad is automatically shut down to ensure safety at the site. Ultrasonic meters can sense leaks in the 25-100 kHz range and from up to 300 feet away. We also use forward-looking infrared (FLIR) optical gas imaging equipment when conducting routine leak detection surveys.

Sand Traps

We worked closely with a GPU manufacturer to develop a custom-built spherical sand trap that allows for the removal of sand and other debris produced by the wells more efficiently than traditional vertical sand traps. We have two variations operating in the field—a 6k-psi option for the lower-pressured Marcellus wells and an 8k-psi option for the higher-pressured Utica wells.
