Callon pays oil from one month and gas from prior month. So your next check will have Oil for November and Gas and Liquids for October. Callon acquired the assets effective October 1. On the Texas CONG, Primexx is listed as seller for September oil and gas and Callon is listed as seller of October oil and gas. Sometimes there is confusion around final payments and there could be a specific agreement between Primexx and Callon about the royalties. Primexx phone number is still working - 800-754-5908 and 214-369-5909 for messages. You may also want to send an email to Callon about the missing September royalties and ask which company will pay. If you do not get responses, then send certified letters to both companies. In all correspondence with Primexx, state that you are demanding payment of all royalties and any other funds which may be held in suspense. It is possible that Callon is waiting for Primexx to forward the “suspended” September royalties to Callon and that Callon will then make that payment. Be persistent.
