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

Requesting approval for 6 wells in SW Bebob
Field: Be303, Be304, Be305, Be441, Be445
and Be447.
SW Bebob Surface Map
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
