Mosman Oil and Gas Limited (LON:MSMN) told investors that the Falcon-1 well in East Texas has returned to gas and oil (condensate) production on 21 February.
It follows the easing of freezing weather conditions in the state.
"The widespread production challenges in Texas last week, was partly created by the rolling blackouts and freezing weather conditions,” said John Barr, Mosman chairman.
“Mosman is pleased that the operator at Falcon and the on-site contractors have reinstated production and kept downtime to a minimum."
Last week, the company noted that the well was temporarily shut-in since 15 February due to avoid water vapour freezing in the gas lines.
Mosman said the operator expects to have the 50% owned well back on production once freezing conditions end.
