Oil, natural gas and natural gas liquids revenues were $18.0 million and $55.9 million for the three months ended June 30, 2020 (Successor) and 2019 (Predecessor), respectively. For the three months ended June 30, 2020 (Successor) and 2019 (Predecessor), production averaged 14,264 Boe/d and 18,055 Boe/d, respectively. Our average daily oil, natural gas and natural gas liquids production decreased in the three months ended June 30, 2020 (Successor) when compared to the same period in the prior year due primarily to the temporary shut-in of a portion of producing wells across all our operating areas during the months of May and June 2020. Estimated downtime associated with these temporary shut-ins was approximately 5,400 Boe/d for the three months ended June 30, 2020 (Successor). The production decline caused by temporary shut-ins in the current year period was partially offset by new wells put online since the prior year period. Average realized prices (excluding the effects of hedging arrangements) were $13.89 per Boe and $34.01 per Boe for the three months ended June 30, 2020 (Successor) and 2019 (Predecessor), respectively. The amount we realize for our production depends predominantly upon commodity prices, which are affected by changes in market demand and supply, as impacted by overall economic activity, weather, transportation take-away capacity constraints, inventory storage levels, quality of production, basis differentials and other factors.
Lease operating expenses were $10.3 million and $13.5 million for the three months ended June 30, 2020 (Successor) and 2019 (Predecessor), respectively. On a per unit basis, lease operating expenses were $7.94 per Boe and $8.20 per Boe for the three months ended June 30, 2020 (Successor) and 2019 (Predecessor), respectively. The decrease in lease operating expenses in 2020 results from our focus on optimization of production operations and decreased salt water disposal costs due to lower production volumes and less produced water.
Workover and other expenses were $0.5 million and $1.4 million for the three months ended June 30, 2020 (Successor) and 2019 (Predecessor), respectively. On a per unit basis, workover and other expenses were $0.42 per Boe and $0.83 per Boe for the months ended June 30, 2020 (Successor) and 2019 (Predecessor), respectively. The decreased costs in 2020 relate to recent strides in improving well and completion designs and fewer workovers performed.
Taxes other than income were $1.5 million and $3.3 million for the three months ended June 30, 2020 (Successor) and 2019 (Predecessor), respectively. Most production taxes are based on realized prices at the wellhead. As revenues or volumes from oil and natural gas sales increase or decrease, production taxes on these sales also increase or decrease. On a per unit basis, taxes other than income were $1.15 per Boe and $2.01 per Boe for the three months ended June 30, 2020 (Successor) and 2019 (Predecessor), respectively.
Gathering and other expenses were $15.2 million and $11.0 million for the three months ended June 30, 2020 (Successor) and 2019 (Predecessor), respectively. Gathering and other expenses include gathering fees paid to third parties on our oil and natural gas production, operating expenses of our gathering support infrastructure, gas treating fees, rig stacking charges and other. Approximately $2.3 million and $3.3 million for the three months ended June 30, 2020 (Successor) and 2019 (Predecessor), respectively, relate to gathering and marketing fees paid to third parties on our oil and natural gas production. Oil and natural gas production volumes were lower in the current period due to the temporary shut-in of a portion of producing wells during the months of May and June 2020. Approximately $9.5 million and $7.6 million for the three months ended June 30, 2020 (Successor) and 2019 (Predecessor), respectively, relate to operating expenses on our treating equipment and gathering support facilities. While our overall production volumes were lower in the current year period, our produced natural gas in Monument Draw increased as compared to the prior year. These natural gas volumes are processed through our hydrogen sulfide treating plant in the area, which led to higher operating expenses, such as chemical costs, associated with our treating equipment during the current year period. Included in the three months ended June 30, 2019 (Predecessor) are $1.9 million of wellhead-level costs to remove hydrogen sulfide from natural gas produced from our Monument Draw properties. In April 2019 (Predecessor), we installed a hydrogen sulfide treating plant that more efficiently removes hydrogen sulfide from our produced natural gas and reduces our reliance on expensive wellhead-level treating. Also included are $3.4 million of rig stacking charges for the three months ended June 30, 2020 (Successor).
Restructuring expense was approximately $2.2 million and $0.7 million for the three months ended June 30, 2020 (Successor) and 2019 (Predecessor), respectively. During the three months ended June 30, 2020 (Successor), we incurred restructuring charges related to the consolidation into one corporate office and had reductions in our workforce due to efforts to improve efficiencies and go forward costs. In May 2020 (Successor), in furtherance of the consolidation into one corporate office, we exercised a one-time early termination option under the lease agreement for our office space in Denver, Colorado. During the three months ended June 30, 2019 (Predecessor), we incurred costs to fill certain
