I am from Henderson, Texas and I am doing the same thing. Go to the City of Shreveport webpage and type in Haynesville Shale. There is a wealth of info there. Bonus payments averaged $400 per acre several years ago. Recently, some have received $13,400 per acre. Look at factors like nearby pipelines, nearby producing oil wells, what others have received, proximity to the Haynesville Shale, proximity to sweet spots of which Nacogdoches County has one, and what nearby wells have produced by day .5 to 2 million cubic feet per day is the average range. The royalty rate should be 25% after production. Lease for 2-5 years, 3 is average.
