Pearson D. B. #4019 (API 42-357-31589) is a well in Ochiltree County operated by Linn Operating Inc., completed March 20, 1987.
The RRC has issued 3 drilling permits between 1984 and 1986, permitted to 8,750 ft.
It was permitted by Horizon Oil & Gas CO. and has since transferred to Linn Operating Inc. on the wellbore schedule.
Completion filings report 5 formation tops, including Kansas City, Cleveland, Marmaton, Morrow.
Its 2 leases have reported 176K barrels of oil and 1.53M mcf of gas since January 1993, last reporting in July 2026. The leases carry 13 wells, so these are lease totals, not this well alone.
