Rusk County · East Texas field · Vertical
Giles #4R (API 42-401-31921) is a plugged well in Rusk County, plugged February 15, 2019, last operated by Dyersdale Energy L.P..
The RRC has issued one drilling permit, issued August 8, 1984, permitted to 3,800 ft.
It was permitted by Tate, Larry V. and has since transferred to Dyersdale Energy L.P. on the wellbore schedule.
Completion filings report one formation top, including Austin Chalk.
Its lease has reported 16.9K barrels of oil and 623 mcf of gas since January 1993, last reporting in July 2026. The lease carries 4 wells, so these are lease totals, not this well alone.
