The cold snap that hit Texas on Feb. 1 has shut down approximately 600 million cubic feet per day (MMcf/d) of natural gas production across the state, according to a report by Reuters.

According to data from Bentek Energy, production initially fell on Jan. 31 and continued to decline through the following day. As of Feb. 2, production has not yet reached normal output levels.

North Texas’ Barnett Shale is reported to have approximately 250 MMcf/d shut in as of Feb. 1. Only 10% has been recovered in 24-hours time.

In addition to the Barnett, Eagle Ford saw 215 MMcf/d frozen and the east Texas Haynesville/Bossier prospects lost 250 MMcf/d in production.

“Liquids-rich gas is susceptible to freeze offs because it has a higher dew point,” said Matt Marshall, senior energy analyst for Bentek.

Marshall also noted that more shut-ins can be expected in other areas of the southern United States.

According to the report, it was unclear which particular wells are experiencing production shut-ins.
