Thank you, Jeff, and good afternoon, everyone. I'd like to start this morning by saying how pleased we are with our first quarter operational and financial performance. The momentum generated by our improved cost structure and capital intensity leadership was a catalyst for our strong results this quarter and is expected to continue to provide a solid foundation for free cash flow generation.
This morning, I will cover our first quarter operational performance and divestiture progress. Rob will cover our financial results and balance sheet improvement as well as our updated guidance, which includes an increase in guidance for midstream and OxyChem's 2021 earnings.
Our first quarter results are a perfect example of how our ability to consistently deliver strong operational performance has strengthened our financial position. In the first quarter, we generated $1.6 billion of free cash flow, which is our highest level of quarterly free cash flow in a decade. We also closed almost $500 million of divestitures, repaid $174 million of debt and exited the quarter with approximately $2.3 billion of unrestricted cash.
Our plan to stabilize 2021 production at our fourth quarter 2020 exit rate is on track. We delivered first quarter production from continuing operations of over 1.1 million BOE per day, with total company-wide capital spending of only $579 million. We're particularly proud of this achievement, given the operational challenge posed by winter storm Uri.
Our domestic oil and gas operating cost of $7.20 per BOE continued to demonstrate the lasting impact of our cost-reduction measures and includes about $83 million of atypical costs related to the winter storm. I want to note that we have fully recovered from the storm with no lasting impact. Even with incurring storm-related costs in the first quarter, our full year domestic operating guidance has only increased by $0.10 per BOE, which represents a significantly smaller increase than the approximate $0.25 per BOE that the $83 million in total OpEx would have otherwise added. This is a significant achievement made possible by our teams continuously seeking efficiencies and finding innovative ways to safely and effectively lower costs.
In the first quarter, OxyChem benefited from robust PVC pricing and gradual strengthening in the caustic soda market. OxyChem's integration across multiple chlorine derivatives provides us with the ability to optimize our caustic soda production while opportunistically adjusting our production mix to maximize margins. OxyChem's ability to adjust to rapidly changing market dynamics was invaluable during the downturn last year, and we were able to provide critical products to the medical, pharmaceutical and disinfection markets to respond to COVID. Given the recent improvements in the chlorovinyl and caustic soda markets, we expect OxyChem to extend its track record as a market leader and consistent generator of free cash flow.
Additionally, during winter storm Uri, our team was able to safely protect our assets as well as provide essential products to our customers. Our team's effective response limited the storm's impact on facility maintenance cost to an immaterial amount.
Midstream and marketing's outperformance compared to guidance in the first quarter was primarily driven by our ability to optimize long-haul gas transportation in the Rockies, along with the timing impact of export sales. Following the increase in activity in the fourth quarter, our oil and gas business continued to push the envelope with new efficiency gains as we seamlessly transitioned into the first quarter.
Our Permian teams outperformed expectations in the first quarter by setting new drilling records in New Mexico, the Texas Delaware and the Midland Basin, while also driving down costs. Our first quarter Permian achievements are especially impressive as we have now augmented the efficiencies of our Oxy Drilling Dynamics with remote directional drilling, an exciting innovation that allows the drill bit to be steered from a separate location. Being able to control and optimize our operations remotely and instantaneously apply shared expertise to similar activities has numerous advantages that we expect our operations to benefit from in the future.
We also continue to achieve significant efficiency improvements in the Rockies, where in the first quarter, our DJ drilling team reached our lowest average cost per foot in program history. I'd also like to highlight Oman for their best-ever HES performance with no recordables in the first quarter while drilling the longest laterals in Oxy Oman history and achieving record drilling times.
After a pause of the issuance of new drilling permits on federal land earlier this year, we have now started to see the process move forward again with the approval of new permits. We currently do not expect the permitting process to have an impact on our activity levels as we still plan to run an average of 11 rigs in the Permian this year and 2 in the Rockies.
In late April, I testified before the U.S. Senate Energy and Natural Resources Committee in support of lifting the federal leasing moratorium. As I told the committee, continued onshore oil and gas development means high-paying jobs, community reinvestment and meeting energy and product needs during the transition to a low-carbon economy. We look forward to working with Congress and the administration on ways to create clarity and short- and long-term regulatory certainty.
After we announced the sale of our Colombia onshore assets last year, we updated our divestiture plan to sell $2 billion to $3 billion of assets by the middle of this year. Our progress towards this target continues as we closed almost $500 million of sales in the first quarter. Post Colombia, we now have closed approximately $835 million of divestitures and are well on our way to achieving our target. But we will continue to make the best value decisions by weighing the impact of future cash flows in our current environment versus the benefits of meeting a deadline or divestiture target.
Looking back over the last year, I'm particularly proud of the accomplishments our teams have achieved and look forward to the opportunities that lie ahead. Not only have we optimized our portfolio, improved our balance sheet and continued to reduce costs, we've also created the pathway to achieve net 0 emissions. As we take our next steps toward achieving our future goals, including further balance sheet improvement, returning additional capital to shareholders and bringing our first commercial scale direct air capture plant online, we will continue to maintain our low-cost, capital efficient, stable production base with a goal of maximizing free cash flow generation through capital discipline and margin preservation.
Our cash flow priorities are structured with the aim of positioning our company for future success. While we are encouraged by the improving macro environment and are especially proud of our team's ability to maintain and sustain our production base, we will continue to improve our balance sheet until we reach the point where our financial position will support a more meaningful return on capital and return of capital to our shareholders throughout the commodity cycle.
I'll now hand the call over to Rob, who will walk you through our financial results for the first quarter and guidance for the remainder of the year.
