WITSML - Product Volume Flow Component Schema. The name of this flow within the context of this report. This might reflect some combination of the kind of flow, port, qualifier and related facility. Indicates the type of flow that is being reported. The type of flow is an indication of the overall source or target of the flow. A production flow has one or more wells as the originating source. An injection flow has one or more wells as the ultimate target. An import flow has an offsite source. An export flow has an offiste target. A consumption flow generally has a kind of equipment as a target. The Product Flow Port to which the flow is assigned. This is the port on the Product Flow Unit that represents the facility. Only one flow should be assigned to each port within the context of this report. The kind of port that this flow represents: inlet or outlet. This should only be specified if a Product Flow Model is not being referenced. Qualifies the type of flow that is being reported. A second facility related to this flow. For a production flow, this would represent a role of 'produced for'. For an import flow, this would represent a role of 'inport from'. For an export flow, this would represent a role of 'export to'. A timestamp representing the version of this data. A flow (same port and products) with a more recent timestamp will represent the "current" version. This is a pointer to the flow from which this flow was derived. Gas oil ratio. The ratio between the total produced gas volume and the total produced oil volume including oil and gas volumes used on the installation. Gas oil ratio month to date. The gas oil ratio from the beginning of the month to the end of the reporting priod. Water concentration mass basis. The ratio of water produced compared to the mass of total liquids produced. Water concentration volume basis. The ratio of water produced compared to the mass of total liquids produced. The average atmospheric pressure during the reporting period. Temperature of the port. Specifying the temperature here (as opposed to in Period) implies that the temperature is constant for all periods of the flow. Pressure of the port. Specifying the pressure here (as opposed to in Period) implies that the pressure is constant for all periods of the flow. Absolute minimum pressure before the system will give an alarm. The internal differences between this port and one other port on this unit. Reports a product flow stream. A timestamped remark about the flow. Unique identifier for the Product Volume Flow.
