Lorn,
Your 4 parcels of minerals are located in the norther part of Leon County Texas. The main activity seems to be in the southern part of the County. There are some older oil and gas wells in the area of your minerals, numerous dry holes, and plugged oil/gas wells are in the area. One older oil well(API 289-30878) is still producing a small amount of oil in A-500. It was drilled and completed in 1987/Woodbine Formation/Shelley Pate Lease. Well 31450 in A-500 is a shut in oil well. I see no activity in many years in this area.
