Reeves County - Delaware Basin - Alpine High - Bone Springs

I am getting offers on property I own in the description below. The offers are from very low (been told they are a joke) to very high (although high is subjective). Can anyone help me with a direction to take? My research is showing that I need to educate myself as much as possible.
The legal description is
All of section 23, Block C-15, PSL, containing 682.0 acres of land, more or less, Reeves County Texas. Abstract - 4750 in Public School Land
