Volumes produced measurement is essential for royalties and governments participation calculating at crude oil and natural gas production fields concession contracts. This remuneration is a common model and for that, so rules and regulations are issued that must be followed by operators, with very clear procedures to be followed. However, these specifications allow a certain degree of choice among the available technological alternatives, and it is up to the operator to ensure that they meet the specifications. And here there is a difficult decision to be made: should the choice focus only on the cost of CAPEX and OPEX of the technological alternative? Metering stations operating cost (OPEX) and investment cost (CAPEX) varies depending on the measurement technology chosen. But the systems uncertainty also depends on this choice and consequently, directly affects the business risk. Thus, the objective of this work is to analyze these variables, which must be considered in the decision making, starting from a revamp feasibility study of the export gas measurement systems for two practically identical offshore platforms. In the first was considered orifice plate element and for second, the use of ultrasonic flow technology. It was possible to analyze the variation of the total cost of ownership (TCO) for three years operation and compare it with the variation of the involved risk, noting that there is a clear prevalence of the second in relation to the first. And therefore, this analysis must be considered in the decision of the projects of the measurement stations.

The market of oil and gas has many particularities, once it is a natural resource of great value. Due to the fact the resource is owned by nations, it is highly regulated. The volumes traded are high; for this reason, their calculation needs to be performed very carefully, meeting not only the uncertainties and metrological control, but also particularly the tracking of the activities. The technical regulations of measurement adopted by the countries carefully follows many guidelines. The reason is that the established volumes directly affect the calculation of royalties and profit sharing in concession agreements or even a simple ownership shift of the products. Therefore, it is an application with a lot of responsibility, involving a large amount of equipment, software, and execution processes. Therefore, the transfer of data among different entities requires total transparency and security. Blockchain technology, which has been initially developed for the financial market, presents itself as an alternative to ensure reliability, from the sensors in the field to the effective generation of the Monthly Report on the petroleum and natural gas production unit, which is the basic document for determining the remuneration of the owners of the product. This paper presents a technical solution for creating the blockchain validation blocks by the MAC (Media Access Control Address) addressing, which in turn comes from the communication boards of the flow computers and from the Supervisory Stations. There are limitations to extending this solution to the level of field sensors due to the current links of communication, but also because of the way that historical, events and alarm databases of the flow computers are generated. Once these devices exhibit an elevated degree of safety in their operation, the solution herein presented adds a high level of reliability in the fiscal measurement and/or custody transfer.
