Exterran introduces enclosed gas production unit to meet demands of Marcellus ...
Exterran Holdings Inc., a Houston-based provider of oil and gas products and services, introduces the Enclosed Gas Staging Unit (EGPU), designed to accommodate the high pressure environment and frigid climate of the Marcellus shale. The Exterran EGPU regulates the well-file flow, pressure and temperature, and also separates gas and liquids in cold-weather environments.
Utilized on appropriate gas wells to remove liquids from gas prior to further processing or delivery to a pipeline, the Exterran EGPU will facilitate customers in the Marcellus shale get to market faster. The pre-engineered, pre-assembled EGPU includes a gas-fired heater and a prone three-phase separator mounted on an enclosed oilfield skid with instrumentation and interconnect piping that are motion-ready. The enclosure protects the instrumentation and piping in frigid climates. The unit is available in single section, dual unit and quad unit configurations.
To address the high pressure gas found in the Marcellus shale, the EGPU heats the well-channel both before and after flowing through a pressure-reducing choke to help avoid the freezing of water and condensates. Additionally, the temperature controllers in the module maintain the temperature to help avoid freezing, overheating and the formation of hydrates. Standard artifact features include a heavy duty quarter-inch steel heater enclosure, interchangeable and removable fire tube, interchangeable and removable split coils, as well as a nuclear fuel gas scrubber with internal high-level shutdown and fuel gas manifold with high and low pressure regulators.
