Introduction



Project Objectives

Standardize format for reserves data and knowledge transfer between project teams and groups

Improve consistency of reserves data

Increase discovery rate for opportunities

Provide a platform for enhancing other work

processes related to reserves analysis

Steps To Support the Reserves Review Process: Input/Access Reserves Data QC Data Report Data – consolidate and merge

Workflow:

PC Reserves – Excel - Powerpoint

or

PC Reserves – Spotfire

Time spent populating database Used for all ChevronTexaco fields PC-Reserves program is robust and

versatile (complicated). Data display (plotting) is limited to

exporting data to Excel. Valuable data is not being used to

its fullest.

Relationship of PC-Reserves

and Spotfire to the Review

Process



Interaction between all visualizations



Opportunity Example

• Reservoir Level

• OOIP

• Reserves

• Waterflood Flag

Purple Area highlights potential

waterflood opportunity



Opportunity Example

• Reservoir Level

• OOIP

• Reserves

• Waterflood Flag

Select reservoirs

• <45% recovery

• not waterflooded



Benefits

Improves Annual Reserves Review Reserves Data Access (no database knowledge needed by end user) QC reserves data

– negative values, – unrealistic recovery factors– …

Enables year around data analysis by multiple groups Quicker Analysis for waterflood opportunities Quicker Analysis for two stage completion in gas cap



Future Opportunities

Data Analysis from multiple databases Improved Process Guides to automate data analysis work

flows Posters (global internet access for collaboration and

review) Secondary Query Devices “Plots on Demand” Scale By Value Pie Charts
