RSP Permian processes and disburses thousands of interests each month. Our revenue cycle allows for requested changes to your account up until the 15th of each month. Revenue checks are mailed on the last business day of each month, and will cover oil sales for the previous month and gas sales for the month prior to oil sales. As an example, RSP’s June check will cover May oil sales and April gas sales. For newly-drilled wells, initial payments may take up to 120 days after the end of the first month of production sales. Please allow up to 15 days to receive your check in the mail.
