About this data
Oklahoma Corporation Commission (OCC), Oil and Gas Conservation Division. Mark L Shidler Inc is identified by its operator number. Well counts are the wells it is operator of record for today; volumes are what it filed under that number, through Dec 2025 for injection. No oil or gas production is available for Oklahoma. There is a data discrepancy in the 2024 injection record that is still under review: part of that year's volume is not matched to its wells. Statewide and operator totals for 2024 include it; some wells and counties show 2024 as under review instead of a figure. Nothing is estimated.
