2. Problem: Handling Reserve Data
Labor intensive: Extensive resources are used to generate, validate and analyze CVX’s Reserves data
Multiple Evaluation Methods: Differently methods and cutoff parameters are used to analyze and evaluate reserve information. Differences occur from business unit to business unit, from asset to asset, and from reservoir to reservoir
Discrepancies: Differences in techniques and cutoff parameter can create discrepancies in reserve calculations – the asset of all E&P companies
Efficient Evaluation: How can we efficiently evaluate the reserves from the PC Reserves database for use by the corporation?

3. Reserves Review Process
Introduction
Definitions:
PC-Reserves: Reserves reporting Database
Opco: operating company
RAC: Reserves Audit Committee
SBU: Strategic Business Unit
Asset team: field level team
Annual Cycle

4. Project Goals
Provide easy, fast and robust connectivity to PC Reserves Database
Automate commonly performed tasks, such as RAC required plots
Enable quick look QC tools
Create an environment for standard and improved analysis using CVX reserves data

5. Improved confidence in reserves data
Benefits
Reduced analysis time
Improved Data Access
More Intuitive Interface
Automated RAC Templates
Improved confidence in reserves data
Increased use of reserves data through new analysis and classification techniques
Platform for rapid deployment of successful analysis practices

6. Export from PC Reserves
Create your own queries from PC Reserves Ad Hoc Query tool.
Directly load a DecisionSite session from PC Reserves for data analysis
Alternatively export to a file and import data to DecisionSite

7. Direct Access to PC Reserves
Common data requests provided from DecisionSite Interface
Data pre-configured for RAC templates
Common calculations and data manipulations performed “on-the-fly”
Recovery Factors (Current and Ultimate)
R/P
Total Reserves (Risked and Unrisked)
Expected Value Reserves 100%,
Does not require launching PC Reserves
Security of data maintained using standard CVX policies

8. Data Retrieval through DecisionSite
No Database knowledge necessary
Direct Connection to PC Reserves
Load Data Exported from PC Reserves
Common Calculations Created Automatically
***Framework in place for rapid deployment of further additions

12. Data Validation
Allows users to “walk through” routine analysis used to identify quality problems in PC Reserves data
Reserves:OOIP Mismatch
Negative Reserves
Production Reserves Mismatch (Negative Reserves Screen)
Data screened using these processes are labeled for further investigation.

13. Value of DecisionSite Integration
Higher confidence of the quality of reserves data
Improved efficiency in analysis of reserves data
Increased understanding of asset base
Standardization of common practices
Improved opportunity discovery rate
Establishes a platform for deploying new and better methods for analyzing reserve data
