Net income of $352.8 million and a net loss of $48.6 million were recorded for the three months ended March 31, 2023 and 2022, respectively.
Oil, natural gas and NGL revenues were $66.3 million and $93.9 million for the three months ended March 31, 2023 and 2022, respectively. Average net production volumes were approximately 19.4 MBoe/d and 20.4 MBoe/d for the three months ended March 31, 2023 and 2022, respectively. The change in production volumes was primarily due to natural declines. The average realized sales price was $37.99 per Boe and $51.10 per Boe for the three months ended March 31, 2023 and 2022, respectively. The decrease in average realized sales price was primarily due to the decrease in commodity prices.
Other revenues were $13.6 million and $17.6 million for the three months ended March 31, 2023 and 2022, respectively. The change in other revenues was primarily related to the recognition of loss of production income (“LOPI”) insurance proceeds of $13.5 million for the three months ended March 31. 2023 compared to $17.5 million of LOPI proceeds for the three months ended March 31, 2022. The decrease in LOPI proceeds reflects the timing recognition of one additional month of LOPI during the three months ended March 31, 2022.

On a per Boe basis, lease operating expense was $18.89 and $17.92 for the three months ended March 31, 2023 and 2022, respectively. The change in lease operating expense on a per Boe basis was due to lower production.
Gathering, processing and transportation expense was $5.6 million and $8.0 million for the three months ended March 31, 2023 and 2022, respectively.

On a per Boe basis, gathering, processing and transportation expense was $3.21 and $4.36 for the three months ended March 31, 2023 and 2022, respectively.

Taxes other than income were $5.3 million and $7.6 million for the three months ended March 31, 2023 and 2022, respectively. The decrease was due to a reduction in production taxes as a result of lower commodity prices and lower production. In addition, we received a $0.4 million from a one-time positive severance tax adjustment related to our non-operated Eagle Ford operations. On a per Boe basis, taxes other than income were $3.03 and $4.11 for the three months ended March 31, 2023 and 2022, respectively.
