Production Sector Realities

• Well sites and gas gathering locations may be remote, without electrical power, and are frequently unmanned

• Processing locations may be remote, generally have electrical power, and are manned

• Operations are highly variable and depend on a wide variety of driving factors

— Play type (oil or gas)

— Formation type (shale, coal bed methane, tight sand, etc.)

— Formation characteristics (temperature, pressure, etc.)

— Contractual / lease considerations

• Not all technologies...
