There are a series of scrap file sections located east of Block 33, Sections 1 thru 24, which are all GG Houston survey. Section 18, GG Houston is a river section close to Section 7, Block 33. There has been a lot of leasing in Section 18, GG Houston, primarily by Jagged Peak Energy. These companies are good at researching title and you can contact Jagged Peak to see if you own any minerals under your surface tract. In many of these sections, the minerals have been severed from the surface. The surface has been platted and the lots sold only conveyed surface.
