Geothermal Reservoir Characterization & Analysis
Analyze geothermal reservoirs using thermal, pressure, and geochemical data
What You Can Do
You can synthesize multi-source geothermal datasets to identify reservoir boundaries, estimate thermal capacity and permeability, map fracture corridors and fault zones, and forecast production sustainability. Claude interprets complex thermal-hydraulic-geochemical relationships to guide drilling decisions, injection well design, and long-term field development strategy without requiring specialized simulation software.
Features
identify thermal gradients, zone boundaries, and anomalies indicating active fluid flow
calculate permeability and storage coefficients from pressure buildup and falloff test data
use fluid chemistry patterns to trace reservoir connectivity and water-rock interactions
synthesize core data with well logs to estimate productive intervals and flow capacity
map preferential flow paths using pressure and temperature anomaly clusters
estimate resource longevity and optimal extraction rates based on thermal and pressure depletion models
recommend drilling locations based on integrated thermal and structural analysis
evaluate pressure maintenance and thermal recovery scenarios for sustainable operations
Example Output
Example 1: Reservoir Assessment Report
- Temperature log summary: 180–245 °C across 800–1,200 m depth interval; anomalous cooling at 950 m indicates permeable fault zone
- Pressure transient results: permeability ~50–80 mD; storage coefficient suggests 2.5 km² effective reservoir area
- Geochemical interpretation: Na-K-Ca ratios indicate 160 °C reservoir temperature; silica saturation shows active mineral precipitation risk
- Well placement recommendation: Target NW-trending fracture at 1,050 m; avoid southern boundary where temperature drops below 160 °C
Example 2: Production Forecast
- Initial resource: 400 GWh thermal equivalent over 30-year field life
- Pressure decline scenario: 2.5% annual decline without injection; recovery extends to 40 years with 75% reinjection
- Temperature sustainability: Core production well maintains >170 °C threshold with optimal spacing (600 m minimum)
- Risk assessment: Silica precipitation in surface equipment requires descaling protocol every 18 months
