RE:RE:RE:SoPioneer natural resources has a 2021 expected production of over 550,000 bbl per day. It is the production of an E&P company that really drives the share price, not the reserves. Unfortunately reserves are worth only a very small fraction of a company's market cap, it's the production (and midstream, downstream, or chemical divisions) that drives the value of the company. Yes reserves can turn into production, but that takes time.
