Gain/(Loss) on Derivative Contracts
We enter into commodity derivatives instruments to manage the price risk attributable to future oil and natural gas production. We recorded a loss on derivative contracts of approximately $19,147 thousand during the nine months ended September 30, 2022, compared to $18,115 thousand during the nine months ended September 30, 2021. Volatility in commodity prices in the nine months ended September 30, 2022 resulted in realized losses of $24,747 thousand in the nine months ended September 30, 2022 compared to $7,105 thousand in the nine months ended September 30, 2021. For the nine months ended September 30, 2022, unrealized gains were $5,600 thousand, compared to unrealized losses of $11,010 thousand in the nine months ended September 30, 2021. Our average nine months ended September 30, 2022 realized oil price per barrel after reflecting settled derivatives was $89.18, compared to $58.37 in the nine months ended September 30, 2021. Our settled derivatives decreased our realized oil price per barrel by $7.54 in the nine months ended September 30, 2022, compared to $1.48 in the nine months ended September 30, 2021. Our realized natural gas price per Mcf was $8.61 in the nine months ended September 30, 2022, compared to $5.09 in the nine months ended September 30, 2021. Our settled derivatives decreased our realized natural gas price per Mcf by $1.42 in the nine months ended September 30, 2022, and $0.69 in the nine months ended September 30, 2021. As of September 31, 2022, we ended the period with a $1,247 thousand net derivative asset compared to $4,353 thousand net derivative liability as of December 31, 2021.
Interest Expense
Interest expense was approximately $1,193 thousand and $926 thousand for the nine months ended September 30, 2022 and 2021, respectively. The increase in interest expense for the nine months ended September 30, 2022 as compared to the nine months ended September 30, 2021 was primarily due to an increase in the weighted average interest rate, partially offset by a larger outstanding balance on the credit facility during the nine months ended September 30, 2021.
Liquidity and Capital Resources — Fund III
Nine months ended September 30, 2022 compared to nine months ended September 30, 2021
Overview
Our main sources of liquidity and capital resources as of the periods covered by this report have been internally generated cash flow from operations. Our primary use of capital has been for the development and acquisition of oil and natural gas properties. We continually monitor potential capital sources for opportunities to enhance liquidity or otherwise improve our financial position.
As of September 30, 2022, we had no outstanding debt. We had approximately $106,410 thousand in liquidity as of September 30, 2022, consisting of approximately $100,000 thousand of committed borrowing availability under the revolving credit facility and approximately $6,410 thousand of cash on hand.
With our cash on hand, cash flow from operations, and borrowing capacity under the new revolving credit facility entered into by Granite Ridge subsequent to September 30, 2022, we believe that we will have sufficient cash flow and liquidity
