More consistent forecasts
Standardize decline workflows and reduce the variability that comes from personal spreadsheet formats and hidden assumptions.
Systems / Reservoir Forecasting & Reserves
System Overview
Reservoir Forecasting & Reserves System
PetroSphere helps reservoir and asset teams build decline cases, compare forecast assumptions, organize reserve reviews and keep technical outputs in a structured product instead of maintaining fragmented spreadsheets and disconnected review files.
Decline case management
Reserve-ready outputs
Scenario comparison
PVT and technical context
Benefits
Why reservoir and asset teams move these workflows into software.
Versioned reserve cases
Track multiple reserve or planning cases with stored notes, assumptions and comparison views.
Faster technical reviews
Assemble management or partner-facing outputs with less manual formatting and fewer disconnected source files.
Stronger cross-team alignment
Give production, reservoir and planning teams a common place to review the same forecast logic and case history.
Characteristics
Core capabilities and outputs inside the reservoir system.
Core Capabilities
- Forecast modelsArps, Duong and saved custom cases
- Case libraryMultiple assumptions and scenario sets
- Reserves workflowMaterial balance and reserve-case support
- Technical contextPVT, pressure and well history references
- CollaborationShared review across engineering roles
The purpose is not just forecasting faster, but keeping the logic behind the forecast visible, reusable and reviewable.
Typical Outputs
- Scenario comparisonCase-to-case forecast reviews
- Reserve summariesTechnical tables and management-ready exports
- Planning supportBase, upside and downside views
- Review packagesStructured notes and exported files
- AuditabilityVisible assumptions and version history
This is valuable when forecasts support internal planning, budgeting, reserves updates or partner-facing technical reviews.
Included Workflows
The reservoir system groups the recurring forecast and reserves tasks together.

How Teams Use It
A typical operating sequence inside the reservoir system.
Build the base case
Load history, define assumptions and save a structured forecast case with the context needed for later review.
Compare scenarios
Review base, upside and downside cases against operational assumptions, field constraints or reserve interpretations.
Publish the package
Export the technical review, summarize the recommendation and keep the case history stored for future planning cycles.
Next Step
See the forecasting workflow in the demo, then move to a plan with live data access.
If your team is already spending too much time reviewing or rebuilding forecast cases, start with the demo and then compare the Pro and Enterprise plans.

Compare Plans
Pro is usually the right starting point for teams that need decline, reserve and shared engineering case workflows without a large enterprise deployment.
