My brother and I share minerals in T34 R69 to the West of you. I turned down $7,000 to $8,500 per acre 8 months ago. The offer price depended on the day of the week and how badly the land man wanted to close the deal. Who knows if they would have actually paid that price. We currently participate in 4 producing wells. I look like a fool today for not selling, but who knows what the future holds. My point is $900 / acre is a lot less. You would be selling at the bottom of the market -- or it looks like the bottom. The price can't go too much lower. Only you can determine if it is in your best interest to sell.
I looked at the Wyoming Oil & Gas web site to see about drilling permits in your area. The wells being drilled in that area are horizontal so frequently the well bore pulls oil from more than one section. T34 R68 Section 6 is surrounded by 8 other sections. Even if they don't put the drill pad in Section 6, they could drill into Section 6 from one of the other 8 surrounding sections. So I looked for well permits in the other 8 sections. I see permits as follows:
T34 R68 Sec 6: 1 well permitted by Chesapeake
T34 R69 Sec 12: 24 wells with permit application by Anadarko. This section is SW of your minerals
T34 R68 Sec 7: 23 wells with permit application by Anadarko. This section is directly South of your minerals.
T34 R68 Sec 8: 3 wells with permit application by Anadarko. This section is SE of your minerals.
So in theory, any of these wells could be drilling up into your Section 6 minerals -- or not.
So I quickly looked at one Anadarko well shown in T34 R68 Sec7. The well number is 49-009-30733. That well has a Wyoming approved permit. It is shown as a " confidential" well, but there is still information about the well location. The well pad is in the NE Qtr of Section 7 and the drill path goes all the way North to the top of Section 6 in the East 1/2. I don't know if it touches your minerals but about 60% of the well length appears to be in Section 6. So it looks like there is planned drilling activity closer than you might have realized. My guess is, this is not the only well Anadarko plans to drill up into Section 6. More research would answer that question.
When a well permit is approved by the State Of Wyoming, the approved permit will be posted on-line and that permit will show the Township, Range and Section of both the drill site and the bottom hole location. So for example, if the well is drilled in Section 7 and the bottom hole is shown in Section 6, the well is being drilled North into Section 6. There will also be a map attached which you can see the actual bore path of the well. On the map you can see the location of the upper and lower penetration points which is where oil will flow into the well at both the upper and lower ends. This is the info I used to determine that well 9-30733 is going North. You will also need to know how the BLM method for determining the mineral owner participation for each well. In general it involves a circle with a 745 ft. radius from both the upper and lower penetration points and then connect the circles to form the participation area. That is a topic too detailed to go into. Things are measured down to the 10 acre plot. My point is, there is enough info on the Wyoming Oil,and Gas web site to figure out if your minerals will participate in a given well once the permit is approved and if you know how to figure out the details. .
With some work, you can determine if Anadarko plans to drill into the area of your minerals. You can also see the formations that Anadarko plans to drill into. The Powder River Basin has what they call stacked formations so they are testing many different levels in the stack.
I'm sorry if I am losing you with detail. If you want to discuss, send me a private message with you phone number and I will give you a return call. I think the news is better than you might have realized.
