Average daily oil and natural gas production was impacted by the temporary shut-in of production amounting to approximately 300 Boepd and 1,300 Boepd for the year ended December 31, 2021 and 2020, respectively. In February 2021, we temporarily shut-in production due to inclement weather. In May and June 2020, we temporarily shut-in production in response to historically low commodity prices. Current year production was also impacted by third-party processing curtailments and downtime resulting from facility upgrades and repairs. In 2021, we drilled and cased 2.0 gross (2.0 net) operated wells, completed 6.0 gross (6.0 net) operated wells, and put online 6.0 gross (6.0 net) operated wells.
Our total operating revenues for the year ended December 31, 2021 were approximately $285.2 million compared to total operating revenues for the year ended December 31, 2020 of approximately $148.3 million.

Excluding the impact of hedges, Battalion realized 98% of the average NYMEX oil price during the fiscal year 2021. Battalion realized a net loss of $77.9 million on settled contracts during 2021.
