Measurement points showing origin of production to disposition shall be documented using this process.

XTO witnessing activities of
those third-party meters are based these.

Crude oil custody shall be measured by these two methods

The papers for the equipment shall be kept for the current period and one previous period for tracking purposes

A specific device or a combination of devices used to account for and to measure the quantity and quality of hydrocarbon or other fluids is defined as.

This should be reviewed by the local measurement team and preformed only when measurements are outside established tolerances.

This process should be used where witnessing cannot be performed.

Accuracy requirements for Instruments used in this process may need to be more accurate than those for Process Measurements

This process must be applied when departing from defined measurement standards.

This should be inspected on an annual basis if a field/plant shutdown would not be required.

This person must ensure that the shakeout, gravity test, and temperature readings are determined as per API procedures

This method is the only way to determine both sediment and water in one test.

ExxonMobil (EMPC) manual Part 6 refers to this as.

These are calibrated at a laboratory flow loop facility traceable to a National Metrology Institute (NMI) or proved/verified using a master meter in series.

These cannot be used for custody transfer without an approved exception

These devices should have the ability to simulate temperatures to within a resolution of 0.2 °F.

This system is structured to promote ongoing integrity of business controls.

These should be located as close to the sample point as possible with a proper shelter should be maintained

This point is to be agreed on by the Operations Technician and the Purchaser.

The two devices are most frequently used as a pressure source
