Live Oak County · Sugarkane (Eagle Ford) field · Temp Abandoned · Horizontal
Three Sisters 01 #01H (API 42-297-34895) is a horizontal well in Live Oak County operated by Marathon Oil EF LLC, completed August 12, 2019 and listed as temp abandoned on the RRC schedule, shut in December 1, 2016.
The RRC has issued one drilling permit (amended once), issued May 27, 2010, permitted to 12,858 ft.
It was permitted by Pioneer Natural Res. USA, Inc. and has since transferred to Marathon Oil EF LLC on the wellbore schedule.
Completion filings report 4 formation tops, including Wilcox, Midway, Austin Chalk, Eagle Ford.
Its 2 leases have reported 222K barrels of oil and 1.42M mcf of gas since August 2010, with no volume in the three years through April 2026. The leases carry 2 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Sep 4, 2013. Density, Neutron, Resistivity. 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.
