What's new in Maximus 7.6

With Maximus 7.6 we continue with the transition of Maximus from a primarily design tool to a tool that can be used across the project lifecycle, from early stages of design to operations management and field-wide production optimization.

List of changes in Maximus 7.6

  • New or improved functionalities
    • Automatic plotting of IPR curves
    • Ability to superimpose a VFP curve onto IPR curve and thus display Nodal Analysis plot for a well
    • Ability to utilize VLP curves to model the wellbore performance from Bottom Hole to Wellhead
    • Tuning of a complete field to known pressures and flowrates
    • New constraints added to Gas Lift Optimization including: Min. & Max. flowrate, Max. Drawdown, Min, FBHP, Min. & Max. WH velocity
    • Sensitivity studies can turn GLO on or off
    • Added new Model Variable Functions. See Maximus Help System for more details.
    • Direct coupling with the Reservoir Simulator 6X from Ridgeway Kite
    • Improvements to the UWA Hydrate model
    • Updated pipe schedule database
    • Allow option to set ambient temperature as a depth for whole system
    • Added Gas Sizing equation for chokes
    • Auto-save model prior to a simulation
    • WGR & GWR added as option to Phase ratios for Black Oil
    • Added X-axis variable option for sensitivity analysis when changing-in-step
    • EOS AGA-8 added for natural gas systems
  • Interfacing and performance
    • Maximus engine release in KBC Acuity for deployment of cloud-based production digital twins
    • Re-organized Ribbon bar is now the default view
    • Improvements to the GIS map functionality
    • New workflow for adding gas lift injection points into a tubing
    • Ability to utilize SLB's OLGA-S (2P, 3P & HD) when it's purchased directly from SLB. Users need to request an AOL 3-J1 OLGA-S type license from SLB.
    • Update to Multiflash 7.5
    • Close model option added to File menu
    • Short length unit added for pipe ID, etc.
    • User can specify a range and step size, when adding sensitivity values
    • MP profile button on results changed to Flow Map

List of known issues in Maximus 7.6

Object Reported issue Issue # Work around
General Oil-water LGS surface tension is inconsistent with Multiflash results BZ-21877 Switch model setting to Sutton+MCSA
General Event configurator crashes when Del is pressed several times BZ-21874 Avoid pressing Del more than twice in a row.
Completion Closing a model while running a Plot VFP calculation causes a crash BZ-21867 Cancel the calculation or wait until calculation is finished before closing the model
Tuning tool Closing a model while tuning is still running causes a crash BZ-21859 Stop calculation or wait until calculation is finished before closing the model
