The oil and gas drilling process in its implementation has a work agreement contract process that will affect activities from drilling services into organizational income. In this paper, the authors conduct research on the business processes that occur in a drilling service organization in the revenue line, such as making billing documents for the work done. We validate the equality of information criteria with experts in the administration of drilling services with information criteria in public administration. Finally, the business processes that occur and the comparison of the duration of the process in the drilling service standard with the realization process are also described to identify the problem and determine the possibility for business processes development with BPR.
