I'm not sure where to post this. Please bear with this newbie as I explain. My brother sold me his working interest in an OK oil and gas well in 1989. I have a 3.57 leasehold interest and a 3.12 WI with a net revenue interest of 2.34. I received checks fairly regularly for about 20 years. The checks stopped coming a few years ago and after much digging, I found a cell number for the operator. I was told it had broken down and would not be repaired.
Earlier this year, I received correspondence informing me that the well would be plugged and asked if I had an objection. I did not. Recently, I received a bill for nearly $1,000. There is no contact info other than a PO box. There is very little detail on the invoice except a beginning balance of about $1400 and a credit around $500.
Should I be asking for a better detailed accounting, or is this typical?
Is an expense like this ever negotiable?
How can I protect myself from future invoices from this company?
