Assay consists of a number of different tools which integrate tightly to provide comprehensive crude oil management. These tools are accessed by using different Documents.
Documents allow you to work with several different crudes at the same time, enabling you to
rapidly build and compare assays See Documents overview.
Documents are accessed using the Document Navigator, which manages your open assays and allows you to quickly access to the assay Database.
See Document navigator.
Data modules
Assay contains several different modules to help manage crude oil data:
|
Module |
Description |
Reference |
|---|---|---|
|
Database |
Used for organising (including sorting, grouping and filtering) and viewing the list of crudes. |
|
|
Profile Graph |
Used for viewing property profiles for crudes, and for graphical cross hair functions. Additionally, when using the AssayEditor, the graph becomes interactive and allows you to modify property profiles. |
|
|
Scatter Graph |
Used for displaying any pair of crude property values, for all crudes in the database, plotted against one another as an (x, y)-scatter. |
|
|
Residue Graph |
Used for viewing residue profiles for crudes, and for graphical cross hair functions. Additionally, when using the AssayEditor, the graph becomes interactive and allows you to modify residue profiles. |
|
|
Bar Graph |
Used to view the value of cut properties on a bar chart for one or more assays. For each selected assay, the value of the property for the selected cuts is shown as a bar on the bar chart. |
|
|
Viscosity Graph |
Used for viewing kinematic viscosity versus temperature, for each selected cut of a crude. |
|
|
Distillation Graph |
Used for viewing the fitting of distillation data when this is included in the Measurement Grid and a flowsheet is associated with the streams in the grid. |
Document types
The different Documents enable you to create new crude descriptions, either by manually editing them or blending together other descriptions:
|
Module |
Description |
Reference |
|---|---|---|
|
AssayWorkup |
Used for working up raw laboratory measurements for a crude oil and its products, to a fully balanced, recuttable and graphable crude description. |
|
|
AssayEditor |
Used for editing crude data and updating Property Profiles. |
|
|
AssaySynthesis |
Used for synthesising a complete crude assay from limited measurement information. |
|
|
ProductSynthesis |
Used for synthesising end product (such as kerosene) from limited measurement information. |
|
|
AssayUpdate |
Used for reflecting changes for all properties of a known crude using only a few new measurements. |
|
|
BlendAnalysis |
Used for determining the most likely blend of known constituent crudes, given a limited set of measurements on the blend. |
|
|
Blend |
Used for blending together any number of crudes in either weight or volume ratios. |
|
|
Generic Feedstock |
Used to store the properties of non-crude feedstocks (such as vegetables oils) in Assay. These feedstocks can have their properties added, but missing properties cannot be calculated. Also no cuts are possible. |
|
|
Real-Time Crude |
Used for creating an assay based on infra-red spectral analysis of a sample. |

These different document types allow easy transfer of data between one another. The Graph Module can always be shown on the right-hand side, allowing the graphical display of data contained in any Document.
