Koonsen #42 (API 42-331-33377) is a well in Milam County operated by Mojo Exploration & Production L, completed October 1, 2019 and listed as producing on the RRC schedule.

The RRC has issued one drilling permit (amended once), issued August 18, 1992, permitted to 1,045 ft.

It was permitted by Winchester Oil & Gas LLC and has since transferred to Mojo Exploration & Production L on the wellbore schedule.

Completion filings report one formation top, including Navarro.

Its lease has reported 451K barrels of oil and 21 mcf of gas since January 1993, last reporting in July 2026. The lease carries 154 wells, so these are lease totals, not this well alone.

It holds an active disposal or injection permit; TexNet located 0 M2+ earthquakes within 10 km over the last two years.

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