4.4 <strong>Oil</strong> <strong>and</strong> <strong>gas</strong> s<strong>to</strong>rage, metering <strong>and</strong> export<br />
The final stage before the <strong>oil</strong> <strong>and</strong> <strong>gas</strong> leaves the platform consists of<br />
s<strong>to</strong>rage, pumps <strong>and</strong> pipeline terminal equipment.<br />
4.4.1 Fiscal metering<br />
Partners, authorities <strong>and</strong> cus<strong>to</strong>mers all calculate invoices, taxes <strong>and</strong><br />
payments based on the actual product shipped out. Often, cus<strong>to</strong>dy transfer<br />
also takes place at this point, which means transfer of responsibility or title<br />
from the producer <strong>to</strong> a cus<strong>to</strong>mer, shuttle tanker opera<strong>to</strong>r or pipeline opera<strong>to</strong>r.<br />
Although some small installations are still operated with a dipstick <strong>and</strong><br />
manual records, larger installations have analysis <strong>and</strong> metering equipment.<br />
To make sure readings are accurate, a fixed or movable prover loop for<br />
calibration is also installed. The illustration shows a full liquid hydrocarbon<br />
(<strong>oil</strong> <strong>and</strong> condensate) metering system. The analyzer instruments on the left<br />
provide product data such as density, viscosity <strong>and</strong> water content. Pressure<br />
<strong>and</strong> temperature compensation is also included.<br />
