Don't know about drilling, but 4 horizontal wells recently filed for permits about 15 miles northeast of Buckhannon. NG prices have finally crossed the $4 mark. This will stimulate drilling, if the NG price stays up.
4 years is way too long to settle an estate without very unusual circumstances. Suggest you contact the Probate Court in the appropriate County and if necessary send a letter to the Supreme Ct of W VA, which has responsibility for disciplining attorneys who take cases and don't follow thru.
I don't buy the excuse about disclosing heirs, but could be wrong without hearing more of the reasoning behind it.
