PC Reserves/DecisionSite
Integration
Improved RAC Process

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?
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
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
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
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
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”

• Does not require launching PC Reserves
• Security of data maintained using standard CVX
policies
Data Retrieval through DecisionSite
No Database knowledge necessary
• Direct Connection to PC Reserves
•Load Data Exported from PC

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
