You are correct - there is activity to the North and West of you (Noble is active with their East Pony project in 9N-59W and Bison has some wells permitted to the West). Your land is definitely worth something with value dependent on several factors (performance of recently drilled offset wells, if it is leased, if so - the terms of the Oil and Gas lease, timing of when wells might be drilled on your minerals).
As you can imagine, minerals with approved spacing orders, under a favorable lease (or with lease activity in the area), and permitted wells or wells being drilled will demand a higher price. Value is determined based on nearby comps and can also be determined through an engineering analysis (forecasting proved undeveloped reserves and future cash flows to come up with discounted net present value).
If you aren't in a hurry you might be better off holding on to your acreage until activity moves closer to you. At that point you can lease them, get the lease bonus and put together a solid case for the value based on nearby activity. If you ever decide to sell, get multiple offers, get help from a competent attorney to review agreements/conveyance docs, and consider getting an engineering evaluation done so you know what your minerals might be worth under likely development scenarios.
