Application Tools
ScaleChem
High-level, industry-oriented
interfaces
ESP, OLI Pro, Analyzers
OLI Engine in Alliance Products
Engine, Databanks
Midrange, general purpose tools
Used across industry domains

Simulation Infrastructure
Recap of market trends
“in the workplace”
 Aging, retiring experts are not easily replaced
 Growing body of interested technologists
■ Field of expertise is other than simulation
and electrolyte behavior
■ e.g. Corrosion Engineers, Production
Chemists, Metallurgists
 Lack of time / manpower / staffing to learn
two new disciplines
 Ongoing tension: relying on consultants
versus developing in-house expertise
THINK
SIMULATION
New focus: Application tools
THINK
SIMULATION
Characteristics / features of these products
High-level interface
Application-specific interface
Incorporates best practices into the simulation
Fixed flowsheets for limited, multiple
configurations
 Multi-step and default orientation
 Recipe driven

SIMULATION
One set of tools per industry domain
■ OLI Tools: Production
■ OLI Tools: Refining
■ OLI Tools: Chemical
 Initial domain chosen: Production
 Expedient because we need to replace ScaleChem
 Eventually branch to other domains
e.g., CDU Overheads (will be client-driven)

Scale prediction
Corrosion prediction
MEG (MeOH) regeneration
Hydrates provide water activity
Squeeze
Interfaces Link to matrix of T, P, flow model outputs
Reservoir chemistry modeling
Scale kinetics link to available model
Multiple zone production fluid mixing in well
Dynamic flow loop testing for scale inhibitors
Reservoir souring (biological activity)
What are the common steps (in scale
prediction)?
THINK
SIMULATION
 Enter a brine
 Enter a hydrocarbon stream (gas or liquid)
 Saturate at reservoir conditions
 Produce the fluid (T, P calculations)
Look at “what-if” Conditional scenarios
Look familiar?
These are the same tasks
recommended for ScaleChem
What are the general goals?
THINK
SIMULATION
 Make the application visual, so that
what is to be done is intuitive
 Make data entry look similar to the fluid analysis reports
 Minimize the “number of clicks”
 Expose the items that are used 90% of the time
■ Other items in the menu or specs button
 Enter data and view results on one-screen, where
possible
 Add new scenario options by adding more calculation
screens (simple screens, more of them)
