John Lee McMaster #155O
Reagan County · Spraberry (Trend Area) field · Vertical
John Lee Mcmaster #155O (API 42-383-36686) is a plugged well in Reagan County, plugged January 18, 2022, last operated by Crescent Energy Operating LLC.
The RRC has issued one drilling permit, issued February 18, 2010, permitted to 9,000 ft.
It was permitted by Broad Oak Energy, Inc. and has since transferred to Crescent Energy Operating LLC on the wellbore schedule.
Completion filings report 3 formation tops, including Spraberry, Dean, Wolfcamp.
Its lease has reported 31.1K barrels of oil and 212K mcf of gas since June 2010, with no volume in the three years through April 2026. The lease carries 4 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Aug 23, 2010. Neutron. These are the logs loaded into Petrora from the Railroad Commission's inventories, not necessarily every log run on the well. The RRC holds the files; each opens from its log search for the well. The kind is the RRC's description of the log; the interval is the one filed for it.

"Spans" is by this well's own filed formation tops: a formation runs from its top to the next deeper top filed, and the deepest runs to the bottom of the log. Depths are measured along the wellbore, so on a horizontal the lateral counts in the formation it was landed in.
