Chandler Gas Unit NO.1 #12 (API 42-293-31887) is a well in Limestone County operated by Hilcorp Energy Company, completed August 22, 2007 and listed as swr-10-well on the RRC schedule.
The RRC has issued one drilling permit (amended once), issued October 30, 2006, permitted to 13,115 ft.
It was permitted by Xto Energy Inc. and has since transferred to Hilcorp Energy Company on the wellbore schedule.
Completion filings report 6 formation tops, including BMA, Pettit, Travis Peak, Cotton Valle Sand.
Its 3 leases have reported 527 barrels of oil and 2.14M mcf of gas since August 2007, last reporting volume in April 2026. The leases carry 3 wells, so these are lease totals, not this well alone.

Well logs
1 log loaded from the RRC's log index, the latest received Jun 15, 2010. 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.
