Abstract

Crude oil that has been stored at the collection station will be sent to the Oil Refinery to be processed into usable petroleum products. A problem that often occurs during oil delivery operations is the difference in calculating the volume of crude oil transfer between the sender and recipient. Loss of oil during oil delivery is unavoidable in the oil industry, both during transportation and during oil processing. These losses can be caused by the basic properties of oil such as evaporation loss, pipe leaks, measuring instrument errors, theft and so on (Sari, 2018). To avoid oil losses and calculation problems for the sender and recipient, crude oil transfer calculations are carried out using the Quantity Accounting System method. In general, Field Operators are tasked with carrying out work starting from the measurement process, calculations, data entry and reporting production figures. This is done to obtain accountable and auditable oil flow reporting, so oil flow calculations are carried out using the Quantity Accounting System (QAS) method. To obtain reliable calculations, data calculations are carried out from crude oil measurements that have been carried out, using the correct tank tables, accurate calculations and obtaining reliable calculation results for all Indonesian oil activities
