Texas locations come from drilling permits, so most older Texas wells have none and are not listed.
Wells named Denver Unit
Occidental Permian Ltd.'s other wells filed under this lease name in Yoakum County, newest permit first. The RRC gives a gas well its own lease number, so the name is what joins the wells of a unit.
