Subsequent Events [Abstract]
Subsequent Events	12. SUBSEQUENT EVENTS On November 14, 2019, Panhandle closed on the sale of 530 net mineral acres in Eddy County, New Mexico, for $3.4 million. On November 22, 2019, Panhandle signed a PSA to acquire 704 net mineral acres in Kingfisher, Canadian and Garvin Counties, Oklahoma, for a purchase price of $9.65 million (subject to normal closing adjustments). We expect to close on this purchase by the end of the calendar year and it will be mostly funded with cash from our like-kind exchange sales.
