Hamman #4 (API 42-237-39534) is a well in Jack County operated by Oakridge Oil And Gas LP, completed May 27, 2012.

The RRC has issued one drilling permit, issued March 16, 2012, permitted to 6,500 ft.

It was permitted by Dte Gas Resources, LLC and has since transferred to Oakridge Oil And Gas LP on the wellbore schedule.

Completion filings report 3 formation tops, including Pregnant Shale, Marble Falls, Barnett.

Its 2 leases have reported 68K barrels of oil and 2.24M mcf of gas since March 2012, last reporting in July 2026. The leases carry 8 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.
