Intents to drill approved and wells spudded, by year
Counted on the wells it operates today, by the year of each well's latest intent to drill and of its spud date. In Oklahoma a spud date reaches the data with the well's completion report, usually six months to a year after drilling, so 2025 and 2026 are still arriving and are drawn lighter.

About this data
Oklahoma Corporation Commission (OCC), Oil and Gas Conservation Division. Mackellar 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.
