Roy Parks B #3962
Midland County · Spraberry (Trend Area) field · Shut IN · Vertical
Roy Parks B #3962 (API 42-329-37043) is a well in Midland County operated by Cog Operating LLC, completed April 11, 2011 and listed as shut in on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued January 26, 2011, permitted to 10,900 ft.
It was permitted by Pdc Energy and has since transferred to Cog Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Wolfcamp, Strawn.
Its lease has reported 1.18M barrels of oil and 2.02M mcf of gas since December 2010, last reporting in July 2026. The lease carries 13 wells, so these are lease totals, not this well alone.
