Custody Transfer / Fiscal Measurement

Fiscal metering / Custody transfers are all about throughput: quantity! And quality? With Fiscal metering / Custody transfers, the quality or pipeline contents during production and/or custody transfers is often underestimated. This while it's becoming increasingly more important with the stronger variations in compositions around the globe and the scarce nature of Oil and Gas.

Custody transfer / Fiscal metering of Crude Oil

Custody transfer of Natural Gas / LNG

Headquartered in the Netherlands, with access to all the gas producing platforms present in the North Sea. The Turn-Key KPS automatic gas sampling systems are installed in this area at many of the major gas producing companies for custody transfer or fiscal metering purposes. The primary function is to determine the BTU’s, SGU and HC Dew point of the gas streams. Furthermore, the KPS automatic gas sampling systems and LNG sampling systems are used to get information on the status of the gas producing wells and/or the gas being transferred.

Custody Transfer / Fiscal Metering at NAM:

NAM, a 50/50 collaboration of Shell and Exxonmobil, is now the largest gas producer in the Netherlands, with an annual production of around 50 billion m³. 70 % of gas (37 billion m³) comes from the Groningen field and the rest from various smaller fields elsewhere on the mainland and in the North Sea (15 billion m³). Gas produced by NAM covers around 75% of Dutch demand. A recent project at NAM was to build an automatic gas sampling system on an offshore platform for custody transfers / fiscal metering purposes.

With KPS having an installed base on many offshore platforms already, KPS was selected to build this custody transfer and fiscal metering system. As most gas produced today is “wet”, with contaminants and some heavy hydrocarbons that will condense and contaminate the gas stream if incorrectly handled. These contaminants needed to be maintained in equilibrium within the sample at all stages of handling so as not to have a detrimental effect on the final analysis. A requirement of the fiscal metering system was that the natural gas produced could be analyzed with the highest accuracy and in accordance with the latest API 14.1 standard.

The automatic gas sampling system provided allows NAM to better determine the BTU’s, SGU and HC Dew point of the gas at custody transfers / fiscal measurements. Hence to better make up the bill of loading, refute claims and to pay unnecessary tax loads.

KPS Automatic Gas or LNG Sampling Systems are build in accordance with the ISO 8943 / ISO 10715 standards. KPS is capable of providing a truly representative composite sample, giving both the user and his client/supplier confidence.

Custody transfer of Crude Oil

Headquartered in the Rotterdam Europoort area, one of the world's largest oil import and oil export harbors. The Turn-Key KPS Automatic Sampling Systems are installed in this area at all the major Oil Storage Terminals and Refineries for custody transfer or fiscal metering purposes. The primary function is to either make up or check the bill of loading on the pipeline contents.

Custody Transfer / Fiscal Metering at TEAM Terminal:

TEAM Terminal is one of the largest oil storage and transhipment companies in Rotterdam's Europoort Area. With Esso, BP, and Aramco as shareholders, TEAM Terminal handles 30 million m3 crude oil annually. A recent project at TEAM Terminal was to build an automatic crude oil Jet-Mix sampling system for one of the main custody transfers / fiscal metering points at TEAM Terminal.

With KPS having an installed base on all the major import and export lines, KPS was selected to build this custody transfer and fiscal metering system. The custody transfer contained a bi-directional flow through a pipe with a diameter of more than one meter. A requirement of the fiscal metering system was that the crude oil could be analyzed with the highest accuracy class of the ISO 3171.

The independent certification company SGS concluded that the custody transfer / fiscal metering system had an outstanding performance in accordance with the highest accuracy class. This allows TEAM terminal to act in the interests of their users, to better determine the composition of the crude oil at custody transfers / fiscal measurements. Hence to better control the bill of loading, refute claims and to pay unnecessary tax loads.
