Reagan County · Spraberry (Trend Area) field · Vertical
Big Lake (Spraberry) Unit #2 (API 42-383-31247) is a plugged well in Reagan County, plugged March 8, 1996, last operated by Chevron Midcontinent L.P..
The RRC has issued one drilling permit, issued July 13, 1978, permitted to 7,650 ft.
It was permitted by Saxon Oil Company and has since transferred to Chevron Midcontinent L.P. on the wellbore schedule.
Its lease has reported 56.4K barrels of oil and 142K mcf of gas since January 1993, last reporting in February 2009. The lease carries 15 wells, so these are lease totals, not this well alone.
