The document outlines a technical opportunity to reduce methane emissions in natural gas production by installing velocity tubing strings. These strings increase gas flow velocity to remove reservoir liquids without venting gas to the atmosphere. One reported case showed a reduction of 4,680 thousand cubic feet of methane emissions per year per well by eliminating bi-weekly venting. The technology is most applicable to wells with relatively small liquid production and higher reservoir pressure, with a potential payback period of less than three years.

• Velocity tubing strings reduce methane emissions by decreasing the flow cross-sectional area, which increases flow velocity and allows for liquid removal without venting gas to the atmosphere. A gas flow velocity of 1,000 feet per minute is generally required to remove well liquids.
• A reported application of this technology eliminated the need for bi-weekly gas venting of 180 thousand cubic feet per well, resulting in an annual methane emission reduction of 4,680 thousand cubic feet per well.
