Chapman #13 (API 42-355-34033) is a well in Nueces County operated by Sun Exploration Inc., completed June 17, 2011 and listed as producing on the RRC schedule.
The RRC has issued one drilling permit, issued April 21, 2011, permitted to 7,100 ft.
It was permitted by Carter Exploration Company and has since transferred to Sun Exploration Inc. on the wellbore schedule.
Completion filings report 3 formation tops, including L 24, Top Het, Greta.
Its lease has reported 177K barrels of oil and 22.3K mcf of gas since November 2006, last reporting in July 2026. The lease carries 6 wells, so these are lease totals, not this well alone.
