Quantity conversion of oil & gas products


Converting the volumes and weights of petroleum products

When petroleum products are traded, volumes have to be converted into weight, and vice versa. This is a sophisticated task, because the actual volumes change all the time. They are dependent on the temperature during storage, loading and unloading.

It is vital for quantity conversion to be performed 100 percent correctly. Inaccurate or erroneous calculations can affect all follow-up processes along the supply chain – from the safety of the loading and warehousing operations through to the computation of tax liability.

OpenTAS QCM (Quantity Conversion Module) offers a proven, precise and extremely cost-effective set of functions for quantity conversion: One single system for accounting, terminal management, distribution and administration.

Full control of volumes via state-of-the-art technology

OpenTAS QCM gives oil and gas companies full control of their volumes and helps them to render their daily operations more profitable. The solution embeds the standard API (ASTM D 1250-80 and ASTM D1250-04) implementation routines and utilizes the standard API functions to calculate the volume correction factor. It also implements an alternate volume correction factor calculation from the Manual of Petroleum Measurement Standards.

The tool can be deployed as a stand-alone system accessed over RFC (Remote Function Call) as well as in any terminal administration system like OpenTAS. Beyond that it works as an integral part of ERP systems and industry solutions such as SAP IS Oil, providing calculation schemes for SAP HPM (Hydrocarbon Product Management) and SAP SDM (Secondary Distribution Management for Oil & Gas).
