  • Chow Pressure Group
    • Bourdet Derivative option 
    • Use of pressure integral option 
    • Key takeaways note option 
    • Date switch. 
  • DCA & Type Well Upgrade 3.0
    • Rate vs Cum option 
    • Rate vs date option 
    • Import type well into DCA module 
  • Multi-well Diagnostic Plot
    • 2×2 plot 
    • Select all wells option 
    • Select groups to plot ala Type Well 
    • Wells stacked in export 
  • Separator Shrinkage & Common Process Conversion Calculations 
    • 10x speed increase! 
    • Now a simple (default) and advanced (can be toggled on) 
    • Simple: do not database and display wellstream compositions vs time 
    • Advanced: do database and display wellstream compositions vs time 
  • Filtering & Sorting
    • Link the filtering in main well list, top bar well list and mass edit well list. 
    • Keep user filtered list persistent even after logging out / refreshing. User comes back to work to the same state they left. 
    • Nested sorting at multiple levels in mass edit 
    • Be able to filter a project to only a list of wellnames and/or API numbers 
    • Be able to filter in GIS map. 
  • Flowing Material Balance 
    • Lasso fit in multiphase FMB  
    • Bulk run option (run for several wells)

  • Huge Performance Upgrade
    • Upgrade of messaging system, including prioritization of calculations 
    • Upgrade of database system to CloudSQL 
    • Daily database backups with history of 1 week 
    • Use of WebGL to plot 10x as many datapoints on charts 
  • Miscellaneous
    • Project: Restricted – Only project owners can edit BHP and prod data 
    • Plots: New zoom option in all plots 
    • Production Data: Visual delete / graphical delete of production data 
    • PVT: GOR – psat graphical selection edit 
  • Data integration:
    • Upgrade of whitson+ API endpoints. 
    • Upgrade of whitson+ direct database connection process and procedures.

I would also like to take the opportunity to thank you all for the great collaboration and supporting our development.  

… So, What’s Next? 

  • Multi-well numerical model 
  • DFIT interpretation 
  • DQI 
  • Gradient calculations 
  • Gas lift optimizer  
  • Fractional version of Numerical RTA. 
  • Property cross plots  
  • + lots more! 

Next release is scheduled for September 2023. 

PS! Let me know if you don’t want this update e-mail and I’ll not send it to you going forward.
