are available to meet our future financial obligations, planned capital expenditure activities and liquidity requirements. Our future success in growing our proved reserves and production will be highly dependent on net cash provided by operating activities and the capital resources available to us.
Based on strip prices as of June 30, 2023, we believe that net cash provided by operating activities and available borrowings under the Credit Facility will be sufficient to meet our cash requirements, including normal operating needs, debt service obligations, capital expenditures and commitments and contingencies for at least the next 12 months.

Operating activities. Net cash provided by operating activities was $1.5 billion and $499 million for the six months ended June 30, 2022 and 2023, respectively. Net cash provided by operating activities decreased primarily due to lower commodity prices, a $202 million payment for early settlement of our swaption agreement and increased gathering compression, processing and transportation expenses, contract termination expense, general and administrative expenses (excluding equity-based compensation expense) and lease operating expenses, partially offset by increased production and decreased net marketing expense, production and ad valorem taxes and interest expense between periods.
Our net operating cash flows are sensitive to many variables, the most significant of which is the volatility of natural gas, NGLs and oil prices, as well as volatility in the cash flows attributable to settlement of our commodity derivatives. Prices for natural gas, NGLs and oil are primarily determined by prevailing market conditions. Regional and worldwide economic activity, weather, infrastructure capacity to reach markets, storage capacity and other variables influence the market conditions for these products. These factors are beyond our control and are difficult to predict.
Investing activities. Net cash used in investing activities increased from $475 million for the six months ended June 30, 2022 to $638 million for the six months ended June 30, 2023, primarily due to an increase in capital expenditures of $160 million between periods. The increase in capital expenditures between periods is primarily due to increased drilling and completions activity and land purchases, as well as higher drilling and water costs between periods.
Financing activities. Net cash flows used in financing activities for the six months ended June 30, 2022 were $1.0 billion, as compared to $139 million in net cash flows provided by financing activities for the six months ended June 30, 2023. During the six months ended June 30, 2022, we redeemed $585 million aggregate principal amount of our 2025 Notes, repurchased $50 million of our 2029 Notes and $13 million of our 2026 Notes, repurchased approximately 9 million shares of our common stock at a total cost of approximately $293 million, distributed $67 million to the noncontrolling interest in Martica and paid $65 million in employee withholding taxes for vested equity-based awards. Additionally, we borrowed $71 million, net, on our Credit Facility during the six months ended June 30, 2022. During the six months ended June 30, 2023, we borrowed $325 million, net, on our Credit Facility, partially offset by distributions to the noncontrolling interests in Martica of $83 million, repurchases of approximately 3 million shares of our common stock at a total cost of $75 million and payments for employee withholding taxes for vested equity-based awards of $27 million.
2023 Capital Budget and Capital Spending
On February 15, 2023, we announced a net capital budget for 2023 of $1.025 billion to $1.075 billion. Our budget includes: a range of $875 million to $925 million for drilling and completion and $150 million for leasehold expenditures. We do not budget for acquisitions. During 2023, we plan to complete 60 to 65 net horizontal wells in the Appalachian Basin. We periodically review our capital expenditures and adjust our budget and its allocation based on liquidity, drilling results, leasehold acquisition opportunities and commodity prices.
For the three months ended June 30, 2023, our total consolidated capital expenditures were $287 million, including drilling and completion costs of $247 million, leasehold acquisitions of $36 million and other capital expenditures of $4 million. For the six months ended June 30, 2023, our total consolidated capital expenditures were $628 million, including
