10 Fluid and PVT Analysis: Data Model
|For Standard||PRODML v2.0|
This chapter describes the PVT data model, which is composed of the key data objects shown in Figure 10-1 and explained in the sections below.
Note that common to several objects, wherever fluid composition is required, is a system for describing the fluid composition in terms of a catalog of fluid components and their properties; this is described in Section 10.7 Fluid Composition .
The Standard Conditions element is used in many of the PVT objects. A choice is available – either to supply the temperature and pressure for all the volumes which follow, or to choose from a list of standards organizations’ reference conditions. Note that the enum list of standard conditions is extensible, allowing for local measurement condition standards to be used. See Figure 2.3-2 which shows the Abstract Temperature Pressure class: this is the type for standard conditions in all PVT objects.
Chapter 11 Fluid and PVT Analysis: Worked Examples provides an explanation of the examples (files) included with the PVT data object download. The objective is this: An understanding of the basic data model described in this chapter combined with the example files and related explanations provide good working knowledge of how PVT works and can be used.
