Zephyr Operating Co LLC intents to drill

In Oklahoma a drilling permit is an intent to drill, approved by OCC. A well can hold several: the first, its amendments, a recompletion. This is one row per well under its newest approved intent, with what has happened since. For intents approved since mid-2025 the wellbore type and target formation are not in the data yet, so the newest rows show a depth and a dash for the rest.

About this data

Oklahoma Corporation Commission: the latest intent to drill on each well record, with its approval date, the formation and depth the operator proposed, and the well's spud date where one is on file. A well whose intent to drill was re-approved appears once, under its latest approval. What the intent to drill is for is OCC's application type, in shared words with OCC's own beside them. Nothing is estimated.
