What is iRAVE?
iRAVE
 Is an acronym for integrated Reservoir Analysis &
Visualization Environment
 Created in the Spotfire environment

iRAVE Data Sources
 Files from Operator
Current focus is
static/dynamic
reservoir and
production data
(no financials)
 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
 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

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

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…
 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

Issues:

Are well locations acceptable?
Completion intervals okay?
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
 Integrated platform allows improved decisionmaking, 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
 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

Future Work
 Integrating other data elements
• Stimulation Results
• Pump Replacements
• Production Attribute Background Maps
• Well Pay Summaries
• Simulation History-Match Data
 Application windows
• Stimulation Uplift Tracker & Predictor
• Areal Bubble Maps
• Waterflood Analysis
• After-Before Compare (ABC) Plots
• Downtime Analysis
• Artificial Lift Analysis
