Capture of Methane and Air Emissions

Natural gas, or methane, is a valuable product that is essential to California’s economy and society. California Resources Corporation (CRC) devotes significant resources to capture natural gas, both in design and construction of new facilities and in retrofitting existing facilities, to minimize air emissions and reduce flaring. The vast majority of the natural gas we produce is either used to generate electricity by us or other electricity producers or transported by utilities to California homes, farms and businesses. Delivering natural gas to a utility or power plant customer typically requires processing facilities and pipelines. When processing facilities or pipelines or the customer’s power plant are not available, such as during maintenance, we flare natural gas under permits issued by regulatory agencies. Flaring is a safe process that combusts the natural gas and allows us to maintain wells and reservoirs at our fields in a steady state of operation. The flaring equipment and emissions are regulated by federal and state agencies. We seek to minimize flaring through technologies such as vapor recovery, microturbines and compressed natural gas (CNG) production. In 2016, a third party discontinued its gas transmission pipeline service to one of our fields, preventing us from transporting our natural gas to our utility customers. Although we have a permit to flare the natural gas, CRC’s Sustainability Team worked diligently with another company to install a CNG operation at our oil field. This CNG process has both significantly reduced our flaring and generated a useful product that powers our steam generation at another field. Applying vapor recovery technology similarly enables CRC to capture additional hydrocarbons for beneficial use or sale.

Vapor Recovery System

CRC installed the highlighted vapor recovery system, shortly after acquiring the pre-existing oil tank battery from another company, to capture and eliminate sources of air emissions.
