Gas filter separators generally have two stages, a particulate filter-coalescer with replaceable elements, followed by a separator to knock out the coalesced liquids. It holds dozens of replaceable filter elements, which are accessed by a closure at one end of the pressure vessel. The separated liquids are collected in sumps below the pressure vessel.

Gas Lift Mandrels are tubing retrievable wherein it is deployed and retrieved attached to the production tubing. Gas lift mandrels are manufactured with heavy-duty lug welded to the outside surface so as to protect the valve & check valve during running in and pulling out operation. Gas lift mandrels are tubing retrievable equipment with receptacles for wireline gas lift valves.

Gas lift valve is used in a gas-lift system to control the flow of lift gas into the production tubing conduit. The gas-lift valve is located in the gas-lift mandrel, which also provides communication with the lift gas supply in the tubing annulus. Operation of the gas lift valve is determined by preset opening and closing pressures in the tubing or annulus, depending on the specific application.

Gas measurement services can help company to save money and assist the flow of data to downstream systems to aid in near real-time decision-making and maximize productivity by delivering a disciplined and professional approach to natural gas measurement and management of the resulting data.

Drilling landfill gas well is a necessary process for recovery and control of the gas produced by the decomposition process. Placing the wells typically requires puncturing the landfill cap, then excavating a hole 24 to 36 inches in diameter down 40 to 140 feet. Large quantities of landfill gas such as methane, carbon dioxide and traces of oxygen, hydrogen sulfide and nitrogen may escape into the surrounding environment during drilling and may continue until the well is capped. A proper-fitting gas recovery system can box-in drilling hazards at landfills.

A geophysical exploration system utilizes a single conductor cable connected to a current source. This cable contains a number of earth probes coupled to it at spaced points with addressable switching units. In order to the probes inject current into the earth, the switching units are activated in sequence. At locations spaced from the probes the resistivity is measured and recorded for each injection. Resistivity measurements are compared with anomaly models to find a match of patterns, indicating the presence, size, and location of an anomaly.

Geophysical survey is a systematic collection of geophysical data for spatial studies. Geophysical survey may use a great variety of sensing instruments, and data may be collected from above or below the earth's surface or from aerial or marine platforms. It has many applications in exploration geology, archaeology, and engineering.
