Opening new doors with Chemistry THINK SIMULATION! 24 th Conference October 23-24, 2007 Product Development Pat McKenzie & A.J. Gerbino, AQSim October 2007 Future for Upstream Applications
THINK SIMULATION Think SIMULATION! Upstream Oil and gas production Downstream Refining Specialty Chemicals Industry – problem domains and where OLI provides value -added Process simulation & electrolyte thermodynamics Metals & mining Power (including nuclear)
THINK SIMULATION Think SIMULATION! How OLI provides value-added Midrange, general purpose tools Used across industry domains High-level, industry-oriented interfaces Engine, Databanks ESP, OLI Pro, Analyzers OLI Engine in Alliance Products Turnkey, consulting, training Electrolyte and Simulation Infrastructure Application Tools ScaleChem Opportunity!
THINK SIMULATION Think SIMULATION! 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 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
THINK SIMULATION Think SIMULATION! 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)
THINK SIMULATION Think SIMULATION! Project stakeholders OLI AQSim Possible industry partner Possible (external) software development team ScaleChem users
THINK SIMULATION Think SIMULATION! 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)
THINK SIMULATION Think SIMULATION! 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
THINK SIMULATION 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)
THINK SIMULATION Think SIMULATION! Select ion to balance Make Duplicate Hide Zero Row Balance Options 1) Data Entry 2) Basic/Expanded chemistry 3) Charge Balance 4) Reconciliation 5) Solids on/off 6) Use Results Key Features: BASIC WATER ANALYSIS
