Prellop #3RE
Lee County · Giddings (Austin Chalk-3) field · Producing · Horizontal · Sidetrack
Prellop #3RE (API 42-287-31328) is a horizontal well in Lee County operated by Magnolia Oil & Gas Operating LLC, completed December 9, 1999 and listed as producing on the RRC schedule.
The RRC has issued 3 drilling permits between 1982 and 1999, permitted to 8,830 ft.
It was permitted by Union Pacific Resources Company and has since transferred to Magnolia Oil & Gas Operating LLC on the wellbore schedule.
Completion filings report one formation top, including See Original Completion.
Its lease has reported 121K barrels of oil and 102K mcf of gas since January 1993, last reporting volume in April 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
