Karnes County · Sugarkane (Eagle Ford) field  · Horizontal

Ridley 01 #02H (API 42-255-32196) is a horizontal well in Karnes County operated by Marathon Oil EF LLC, completed February 5, 2012.

The RRC has issued one drilling permit (amended once), issued November 21, 2011, permitted to 21,000 ft.

It was permitted by Pioneer Natural Res. USA, Inc. and has since transferred to Marathon Oil EF LLC on the wellbore schedule.

Completion filings report 3 formation tops, including Carrizo, Midway, Eagle Ford.

Its 2 leases have reported 2.87M barrels of oil and 6.55M mcf of gas since February 2012, last reporting in July 2026. The leases carry 12 wells, so these are lease totals, not this well alone.

The sources disagree, which usually means a transfer or a lease-level production filing by a different entity. Petrora goes with the schedule.
