I have mineral rights and a property share on property in Pecos, Tx.

I am going to assume you got these mineral rights from a deceased relative because of the category you chose. If your relative had a will, you will need to send their estate to probate for the property to be placed in your name. If your relative did not have a will, there is another option you will need to take to have the property placed in your name. In either case, you will need to go to court or file a document stating that you are an heir or beneficiary of their property. Once that has been done, you will need to file the judge's order with the deed office in Reeves county.  After that, any operating oil companies will need to be notified that any money they have designated for your relative should now be directed to you. It is a fairly complicated process, but I tried to explain it as simply as possible. Please contact an attorney to discuss this matter as soon as possible.
