Well Plugging
A reduced emissions completion (REC) is a practice that employs equipment to capture gas produced during well completions following hydraulic fracturing and deliver it to the sales line. Compared to traditional completions, RECs reduce methane emissions.

Plunger Lift System Without Planned Atmospheric Venting
Installing a plunger lift system is an effective method for removing accumulated liquids and restoring gas pressure. Plunger lift systems without planned venting eliminate the emissions associated with well blowdowns used to remove the accumulated liquid.

Pipeline Hot Taps
Hot tapping is a procedure used to make a new pipeline connection while the pipeline remains in service, flowing natural gas under pressure. The operator can make a new connection without having to shut down the pipeline or performing pipeline blowdown.
