Desiccant Dehydrators

Replacing glycol dehydrators with desiccant dehydrators that use moisture absorbing salts to remove water reduces dehydrator emissions and also results in lower operating and maintenance costs.

Air Starters use compressed air, instead of natural gas, to start internal combustion engines for compressors, generators, and pumps. This mitigation option eliminates methane emissions from engine start-ups.

Well Completions and Workovers

Well completion is the process of bringing an oil or gas well into production. Completion steps involve casing, cementing, perforating, hydraulically fracturing in the reservoir, expelling fluids, and installing the production valve.

Compressor Station Blowdowns

Compressor stations are taken offline (depressurized) for operational or maintenance needs. To take a compressor station offline, station or unit isolation valves are closed and the gas within the compressors is vented to the atmosphere (i.e., blowdown).

Compressor Starts

Compressors driven by gas engines are often equipped with small gas expansion turbine motors to start the engine. These motors initiate startup of the engine with expansion of pressurized gas across the starter turbine; that gas is then vented.

Marginal Conventional Wells

Well completion is the process of bringing an oil or gas well into production. Completion steps involve casing, cementing, perforating, hydraulically fracturing in the reservoir, expelling fluids, and installing the production valve.

Dasymetric Toolbox

Dasymetric mapping is a geospatial technique that uses additional information, such as landcover types, to more accurately distribute data that has been assigned to arbitrary boundaries, such as census blocks.
