Exterran Holdings Inc., a Houston-based provider of oil and gas products and services, introduces the Enclosed Gas Production Unit (EGPU), designed to accommodate the high pressure environment and frigid climate of the Marcellus shale. The Exterran EGPU regulates the well-stream flow, pressure and temperature, and also separates gas and liquids in cold-weather environments.

Utilized on natural gas wells to remove liquids from gas prior to further processing or delivery to a pipeline, the Exterran EGPU will help customers in the Marcellus shale get to market faster. The pre-engineered, pre-assembled EGPU includes a gas-fired heater and a horizontal three-phase separator mounted on an enclosed oilfield skid with instrumentation and interconnect piping that are operation-ready. The enclosure protects the instrumentation and piping in frigid climates. The unit is available in single unit, dual unit and quad unit configurations.

To address the high pressure gas found in the Marcellus shale, the EGPU heats the well-stream 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 unit maintain the temperature to help avoid freezing, overheating and the formation of hydrates. Standard product features include a heavy duty quarter-inch steel heater enclosure, interchangeable and removable fire tube, interchangeable and removable split coils, as well as a fuel gas scrubber with internal high-level shutdown and fuel gas manifold with high and low pressure regulators.

Exterran’s gas production unit has a round heater design, a durable heater shell, and is has customizable configurations for installation of a different separator, coil, fire tube and meters.
