Operating Revenues. Oil, natural gas and NGLs revenues were $ 49.1 million and $53.9 million for the three months ended June 30, 2024 and 2023. The decrease in revenues is primarily attributable to our lower production volumes in 2024 compared to 2023 partially offset by an increase in average realized prices. Average realized prices (excluding the effects of hedging arrangements) increased approximately $0.40 per Boe for three months ended June 30, 2024 when compared with the same period in 2023.
Oil, natural gas and NGLs revenues were $98.6 million and $118.2 million for the six months ended June 30, 2024 and 2023, respectively. The decrease in revenues is primarily attributable to a decrease in our average realized prices and lower production volumes in 2024 compared to 2023. Average realized prices (excluding the effects of hedging arrangements) decreased approximately $0.96 per Boe for the six months ended June 30, 2024 when compared with the same period in 2023. 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.
Production averaged 12,857 Boe/d and 14,253 Boe/d for the three months ended June 30, 2024 and 2023, respectively, and 12,923 Boe/d and 15,221 for the six months ended June 30, 2024 and 2023, respectively. Production was lower in the second quarter and year to date period 2024 compared with the same period in 2023 due largely to the timing of capital expenditures spent to bring new wells online and natural production declines on our existing producing wells. Over the twelve months preceding June 30, 2024, we put online 4 gross (3.93 net) operated wells while in the twelve months preceding June 30, 2023, we put online 7 gross (6.5 net) operated wells. Also impacting 2024 production volumes was curtailment in Monument Draw due to downstream throughput limitations causing increased downtime and shut-in production.
Lease Operating Expenses. Lease operating expenses were $11.0 million and $11.4 million for the three months ended June 30, 2024 and 2023, respectively, and $22.6 million and $23.1 million for the six months ended June 30, 2024 and 2023, respectively. On a per unit basis, lease operating expenses were $9.41 per Boe and $8.76 per Boe for the three months ended June 30, 2024 and 2023, respectively, and $9.61 per Boe and $8.37 per Boe for the six months ended June 30, 2024 and 2023, respectively. The increase in lease operating expenses on a per unit basis in the second quarter and first six months of 2024 is primarily a result of an inflationary market increase in maintenance, power, and chemical costs combined with lower production.
Workover and Other Expenses. Workover and other expenses were $1.0 million and $2.6 million for the three months ended June 30, 2024 and 2023, respectively and $1.8 million and $4.0 million for the six months ended June 30, 2024 and 2023, respectively. On a per unit basis, workover and other expenses were $0.81 per Boe and $2.03 per Boe for the three months ended June 30, 2024 and 2023, respectively, and $0.78 per Boe and $1.44 per Boe for the six months ended June 30, 2024 and 2023, respectively. The decreased workover and other expenses in 2024 relate to more significant workover projects undertaken in the prior year.
Taxes Other than Income. Taxes other than income were $3.3 million and $3.2 million for the three months ended June 30, 2024 and 2023, respectively, and $6.3 million and $6.4 million for the six months ended June 30, 2024 and 2023, respectively. Severance taxes are based on realized prices and volumes at the wellhead, while ad valorem taxes are tied to the annual valuation of our properties. As revenues or volumes from oil and natural gas sales increase or decrease, severance taxes on these sales also increase or decrease. On a per unit basis, taxes other than income were $2.86 per Boe and $2.45 per Boe for the three months ended June 30, 2024 and 2023, respectively, and $2.70 per Boe and $2.31 per Boe for the six months ended June 30, 2024 and 2023, respectively.
Gathering and Other Expenses. Gathering and other expenses were $12.1 million and $16.8 million for the three months ended June 30, 2024 and 2023, respectively, and $29.4 million and $33.3 million for the six months ended June 30, 2024 and 2023, respectively. Gathering and other expenses include gathering fees paid to third parties on our oil and natural gas production and operating expenses of our gathering support infrastructure. Our gathering and other expenses are primarily driven by the amount and location of natural gas production, the concentration of H2S in our sour gas produced, and the amounts paid to treat our sour gas volumes, either through our own hydrogen sulfide treating plant or through third parties. On a per unit basis, gathering and other expenses were $10.36 per Boe and $12.97 per Boe for the three months ended June 30, 2024 and 2023, respectively, and $12.51 per Boe and $12.10 per Boe for the six months ended June 30, 2024 and 2023, respectively. The decrease in gathering and other expenses per Boe for the three months
