Is there any way to find out if XTO has the deep rights in Survey H & TC CO ABSTRACT 165 SEC. 41 BLOCK 33 WARD COUNTY TX. DIST. 8 ? We are royalty owners in Sec. 41 and noticed XTO drilling in the deep rights zones in the sections next to 41 but Shell isn’t permitting any new options in the deep zones so, wondered if XTO made a deal for the deep rights in Sec. 41. If there is a way to find out the details please let me know.
