Agenda
  • What is iRAVE?
  • Demo Project Overview
  • How  iRAVE is used by Chevron NOJV Team for :
    • Pre Drill well package review/approval
    • Post Drill analysis
    • Current Year Drill Well Results
    • Reservoir Surveillance and Management
  • Summary
    • Conclusions
    • Lessons Learned
    • Best Practices
    • Future Work
what is irave
What is iRAVE?
  • iRAVE
    • Is an acronym for integrated Reservoir Analysis & Visualization Environment
    • Created in the Spotfire environment
irave data sources
iRAVE Data Sources

Current focus is static/dynamic reservoir and production data (no financials)

  • Files from Operator
    • Monthly via DVD
      • Oil Field Manager (MS Access) – production & downtime
      • WellView (MS Access) – well schematics and activities
    • Sporadic
      • Completion Schematics (Adobe PDF)
      • Production Logging (MS Word)
      • MDT Runs (MS Excel)
      • Proposed Drill Production Forecasts (MS Excel)
      • Weekly Well Test Report (MS Excel)
  • Files We Generate (as needed)
    • Well table including proposed drills and other well-specific data not supplied by Operator
    • Log images (Petrel workflow)
irave data upload
iRAVE Data Upload
  • MS Access-based data uploading tool
    • Can specify which data to be updated (reduces wait time)
    • Full upload takes ~30 minutes
    • Data is copied to SQL Server, and new tables are created for use in Spotfire
    • All done by our Geo Tech

MDP-422SW Bebob, Aram
  • Requesting approval for 6 wells in SW Bebob Field: Be303, Be304, Be305, Be441, Be445 and Be447.
  • SW Bebob Development
  • Currently 23 producers , 4 injectors
  • Oil Recovery thru YE 2117 = 10.2 MMBO
  • Estimated current SW Bebob EUR (decline curve) = 21.14 MMBO
  • Forecasted incremental capture reserves from MDP-422 wells = 6.1 MMBO
  • Planned Development (18 acre pattern infill)
  • Multiple YO sands in area
  • All wells to have M1-10 perfs
  • All wells to have M1-20 perfs
  • Tie in to Manifold Be152

how does the chevron team use irave
How Does the Chevron Team use iRAVE?
  • The Chevron Team uses iRAVE for :
    • Pre Drill well package review/approval
    • Post Drill analysis & Current Year Results
before we go live
Before we go live…
  • We use the library function as opposed to WebEx or InfoLinks
  • It can be easily saved on a laptop for portability at offsite meetings
  • We will now go through the basic screens to show how we use iRAVE
well package proposal example mdp 422
Well Package Proposal Example (MDP-422)

Issues: Are well locations acceptable?

Completion intervals okay?

conclusions
Conclusions
  • iRAVE is an emerging technology which enables us to keep up with Operator.
    • Six rigs total
    • 100+ new completions per year
    • ~1,000 stims per year
    • $500 MM - $1,000 MM annual Capex and Opex budget
    • Only one geo and one engineer on Chevron team!
  • Team activities in 2009 generated over $50 MM in NPV utilizing iRAVE and independent mapping to identify project opportunities
  • iRAVE can be applied to other assets with minimal effort
lessons learned
Lessons Learned
  • Integrated platform allows improved decision-making, in some cases, better than the Operator
  • Splitting the process to compile data to a central server separate from the application allows easier adoption to other assets and easily integrate new data
  • This process has helped us influence the Operator by challenging their analysis methods (i.e., IP rates were always optimistic)
  • Plan for due diligence, that is, data clean-up, and influence Operator to improve data sources
best practices
Best Practices
  • 2009 Drilling Results plot – recognized by Chevron’s Internal Reserves Advisory Committee as best practice (type curves and comparison to actual new drills)
  • MDP post-drill analysis – has helped to influence Operator to review their proposals in more detail
