Critical Minerals

Subsurface Solution Minerals Evaluation Services

DeGolyer and MacNaughton (D&M) provides end‑to‑end scientific, technical, and economic evaluations for extracting solution minerals from petroleum brines, geothermal formation fluids, and saline aquifers. Our multidisciplinary offering combines petroleum‑reservoir workflows, geochemistry, laboratory pilot testing, reservoir engineering, and commercial valuation to de‑risk projects and quantify in‑place and recoverable solution mineral resources.

Our services

1. Geological, Brine‑In‑Place & Mass‑In‑Place Assessment
   • Build a three‑dimensional structural and stratigraphic framework from available seismic and well data to define gross reservoir volume.
   • Populate the geological model with petrophysical properties using deterministic and probabilistic methods.
   • Quantify uncertainty and statistical dependencies among model inputs.
   • Assess brine geochemistry: identify mineral concentration trends and spatial/vertical patterns and quantify concentration uncertainty.
   • Estimate stochastically resources: Monte Carlo modeling to produce a probabilistic range of in‑place solution‑mineral resource estimates that reflect input uncertainties and correlations.
2. Laboratory & Field Testing
   • State‑of‑the‑art brine chemistry analysis, including trace elements and rare‑earth element (REE) characterization.
   • Laboratory pilot‑scale extraction and processing tests to define purity profiles and produce representative product samples.
   • Field‑scale pilot testing and validation of extraction, separation, and process flowsheet performance.
3. Techno‑Economic Analysis
   • Economic Assessments that outline capital expenditure (CAPEX), operating expenditure (OPEX), recovery rates, and project economics under multiple development scenarios.
4. Market & Valuation Services
   • Market analysis and demand forecasting for targeted critical minerals.
   • Valuation and NPV modeling for mineral projects, and technical commercial due diligence for M&A and financing.
5. Reservoir Simulation & Field Development Planning
   • Dynamic reservoir modeling to support production/injection planning and optimize recovery.
6. Reserves & Resources Evaluation
   • Classification and reporting of reserves and resources using D&M’s in‑house Solution Mineral Resources Management System (SMRMS), a PRMS‑inspired framework adapted for solution minerals.

Why D&M

• Integrated petroleum reservoir and mineral‑extraction expertise enables rapid, rigorous resource assessment using existing subsurface data and infrastructure.
• Probabilistic, uncertainty‑aware workflows deliver defensible in‑place and recoverable resource estimates.
• Laboratory‑to‑field validation ensures technical feasibility and supports credible economic and commercial decisions.

D&M’s solution minerals service allows operators to transform co-produced formation water into a strategic economic asset.
