A New Tomorrow, Today October 2021 Building a Stronger, More Sustainable Oasis: Transformational Actions to Enhance Shareholder Value Exhibit 99.2

Forward-Looking / Cautionary Statements Non-GAAP Financial Measures E&P Adjusted Gas Revenue, Cash GPT, E&P GPT, E&P Cash G&A, Cash Interest, E&P Cash Interest, Adjusted EBITDA, Adjusted EBITDA attributable to Oasis, E&P Adjusted EBITDA, E&P Free Cash Flow, Adjusted Net Income (Loss) Attributable to Oasis, Adjusted Diluted Earnings (Loss) Attributable to Oasis Per Share and Recycle Ratio are supplemental financial measures that are not presented in accordance with generally accepted accounting principles in the United States (“GAAP”). These non-GAAP measures should not be considered in isolation or as a substitute for natural gas and NGL revenues, gathering, processing and transportation expenses, general and administrative expenses, interest expenses, net income (loss), operating income (loss), net cash provided by (used in) operating activities, earnings (loss) per share or any other measures prepared under GAAP. Because these non-GAAP measures exclude some but not all items that affect net income (loss) and may vary among companies, the amounts presented may not be comparable to similar metrics of other companies. Reconciliations of these non-GAAP financial measures to their most comparable GAAP measure can be found in the annual report on Form 10-K, quarterly reports on Form 10-Q and the Company’s website at www.oasispetroleum.com. Amounts excluded from these non-GAAP measure in future periods could be significant. Cautionary Statement Regarding Oil and Gas Quantities The Securities Exchange Commission (the “SEC”) requires oil and gas companies, in their filings with the SEC, to disclose proved reserves, which are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible—from a given date forward, from known reservoirs, and under existing economic conditions (using unweighted average 12-month first day of the month prices), operating methods, and government regulations—prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data and price and cost assumptions made by reserve engineers. In addition, the results of drilling, testing and production activities of the exploration and development companies may justify revisions of estimates that were made previously. If significant, such revisions could impact the Company’s strategy and future prospects. Accordingly, reserve estimates may differ significantly from the quantities of oil and natural gas that are ultimately recovered. The SEC also permits the disclosure of separate estimates of probable or possible reserves that meet SEC definitions for such reserves; however, we currently do not disclose probable or possible reserves in our SEC filings. Our production forecasts and expectations for future periods are dependent upon many assumptions, including estimates of production decline rates from existing wells and the undertaking and outcome of future drilling activity, which may be affected by significant commodity price declines or drilling cost increases. Forward-Looking Statements This presentation, including the oral statements made in connection herewith, contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical facts, included in this presentation that address activities, events or developments that Oasis Petroleum Inc. (the “Company” or “Oasis”) expects, believes or anticipates will or may occur in the future are forward-looking statements. Without limiting the generality of the foregoing, forward-looking statements contained in this presentation specifically include the expectations of plans, strategies, objectives and anticipated financial and operating results of the Company, including the Company’s drilling program, production, derivative instruments, capital expenditure levels and other guidance included in this presentation, as well as the impact of the novel coronavirus 2019 (“COVID-19”) pandemic on the Company’s operations. These statements are based on certain assumptions made by the Company based on management’s experience and perception of historical trends, current conditions, anticipated future developments and other factors believed to be appropriate. Such statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond the control of the Company, which may cause actual results to differ materially from those implied or expressed by the forward-looking statements. These include, but are not limited to, risks that the proposed transaction between Crestwood Equity Partners LP (“Crestwood”) and Oasis Midstream Partners LP’s (“OMP”) may not be consummated or the benefits contemplated therefrom may not be realized, the ability to obtain requisite regulatory and unitholder approval and the satisfaction of the other conditions to the consummation of the proposed transaction, the ability of Crestwood to successfully integrate OMP operations and employees and realize anticipated synergies and cost savings, the potential impact of the announcement or consummation of the proposed transaction on relationships, including with employees, suppliers, customers, competitors and credit rating agencies, changes in crude oil and natural gas prices, developments in the global economy, particularly the public health crisis related to the COVID-19 pandemic and the adverse impact thereof on demand for crude oil and natural gas, the outcome of government policies and actions, including actions taken to address the COVID-19 pandemic and to maintain the functioning of national and global economies and markets, the impact of Company actions to protect the health and safety of employees, vendors, customers, and communities, weather and environmental conditions, the timing of planned capital expenditures, availability of acquisitions, the ability to realize the anticipated benefits from the Williston Basin acquisition and Permian Basin divestitures, uncertainties in estimating proved reserves and forecasting production results, operational factors affecting the commencement or maintenance of producing wells, the condition of the capital markets generally, as well as the Company’s ability to access them, the proximity to and capacity of transportation facilities, and uncertainties regarding environmental regulations or litigation and other legal or regulatory developments affecting the Company’s business and other important factors that could cause actual results to differ materially from those projected as described in the Company’s reports filed with the U.S. Securities and Exchange Commission (the “SEC”). Additionally, the unprecedented nature of the COVID-19 pandemic and the related decline of the oil and gas exploration and production industry may make it particularly difficult to identify risks or predict the degree to which identified risks will impact the Company’s business and financial condition. Because considerable uncertainty exists with respect to the future pace and extent of a global economic recovery from the effects of the COVID-19 pandemic, the Company cannot predict whether or when crude oil production and economic activities will return to normalized levels. Any forward-looking statement speaks only as of the date on which such statement is made and the Company undertakes no obligation to correct or update any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by applicable law.
