Hi Janet,
Without knowing the particulars (exact location, etc.) it is hard to say. It is likely that you could get more for your minerals if you and your siblings joined together as one group (e.g. someone who owns 15 net mineral acres has more bargaining power than someone who only owns 3). If Anadarko has recently permitted wells then it is a promising sign as to the interest level around your property. If you can wait it out, then it may be worth holding on to your minerals. As you can imagine, the value of your minerals is highly dependent on when wells are drilled and how productive they are. Just because wells are permitted, doesn't necessarily mean that a well will be drilled before the permit expires. It may be that Anadarko wants the option of being the operator in the area and is proactively permitting wells to secure their position. As you probably have seen in your research, IP's sometimes can vary quite a bit and just because big wells were drilled in the county, there can also be significantly lower production just a few townships away.
I'd be happy to give you a quick look and tell you my thoughts if you would like to send me a direct message with info. If you and your siblings are seriously considering selling, I would hire someone to provide a valuation of your minerals to ensure that you are armed with the knowledge of what they are really worth before you enter into negotiations.
Hope this helps!
Thanks,
Matt Sands

Similar to Matt's response below, I would be happy to go over your acreage with you. The area is seeing a material uptick in interest due to the 'stacked' nature of the formations. Further, recent well results have been positive as operators are utilizing more advance completion techniques and obtaining really good results.
If you want to chat PM me and we can connect - I can send you some maps and greater details as to what's going on in your area.
regards,
Jeff
