Shamburger Lake Unit #2403 (API 42-423-31417) is a well in Smith County operated by Valence Operating Company, completed May 5, 1994 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued December 16, 1993, permitted to 7,530 ft.
It was permitted by Umc Petroleum Corporation and has since transferred to Valence Operating Company on the wellbore schedule.
Completion filings report one formation top, including Paluxy.
Its lease has reported 1.21M barrels of oil and 900K mcf of gas since January 1993, last reporting in July 2026. The lease carries 41 wells, so these are lease totals, not this well alone.
