WITSML- Catalog of Value Constrainted Types.
Defines qualifiers for type of flow.
Indicates product characteristics that were allocated back to
a well as opposed to being measured at the well.
Indicates product characteristics that were determined by an
allowable or other performance limit. This includes allowables which are usually
established by a regulatory agency for a product.
Indicates product volumes that were actually
measured at the port.
Indicates product volumes that were derived directly from one
or more other flows.
A performance requirement as determined by a budget.
An estimated or calculated performance, possibly
based on comparable product flow units, but not based on reservoir simulations for
the particular product flow unit.
An amount, set by some authority, which may or may
not be based on technical criteria.
An estimated performance based on a simulation
that includes the particular product flow unit.
