Yes they probably will keep paying dividends (because if they don't they will be removed from all those "dividend aristocrat" ETFs which will be another headwind on their stock price. Typically, when a stock is removed from a major ETF, it tanks their stock price as it represents a "forced sell" by a significant portion of the market). But, should they be taking on more debt to pay increasing dividends (which will further increase their costs and their break-even crude price)? I would say, probably not.
Recently the stock market has become largely speculative in nature (e.g. TESLA has a value of over 1200 times its annual earnings), which is a destabilising factor. Eventually, if a stock does not return cash to its investors (without the cash being from credit or from asset sales) - it will be divested. By that logic, I cannot see a $70+ per barrel in the short to medium term due to lower commercial activity. So, it may be some time before XOM are able to sustainably return to profitability - and that is the question people should be asking instead of whether or not they will continue to pay a dividend.
If they decide not to pay a dividend next time, or reduce it, that will be more prudent, but it would "pull the rug out" from beneath investors and the stock would settle lower. So, if you invest in an unprofitable Company just to take advantage of their (credit derived) dividend, your investment is solely reliant on the continuation of their dividend policy.
