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

THINKSIMULATION

Think SIMULATION!

New focus: Application tools

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

Characteristics / features of these products

Initial implementation

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)

Possible Applications for Upstream

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)?

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

THINKSIMULATION

Think SIMULATION!

What are the general goals?

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)
