Seismic Interpretation Assistant for Oil & Gas Exploration
Systematize fault mapping, stratigraphic analysis, and trap definition from seismic data
What You Can Do
You can use this skill to systematize seismic interpretation workflows without replacing specialized software like Kingdom or Petrel. It helps you organize fault geometry analysis, establish chronostratigraphic frameworks, identify seismic facies patterns, define trap configuration and spill geometry, and assess seal integrity. The skill transforms scattered observations into documented, reproducible interpretive products that support volumetric assessment and drilling decisions.
Features
Organize fault traces, displacement patterns, and fault-seal relationships across 3D survey lines
Systematize seismic horizon picks and document lateral facies changes and stratigraphic relationships
Define hydrocarbon trap configuration, spill points, and closure geometry for exploration risk assessment
Generate multiple interpretation scenarios with documented assumptions and supporting evidence
Identify seismic facies patterns, depositional environments, and chronostratigraphic boundaries from reflection geometries
Integrate regional tectonics, play concepts, and structural styles into interpretation frameworks
Document seal lithology, thickness, and lateral continuity for trap evaluation
Example Output
Example 1: Fault Geometry Analysis
- Input: Cross-section observations of throw magnitude and dip angle changes across two seismic lines
- Output: Documented fault geometry map showing fault trace, displacement variation, and fault-seal risk assessment by segment
Example 2: Trap Definition Summary
- Input: Horizon picks for structural closure and spill geometry from multiple 3D lines
- Output: Trap configuration summary with closure volume calculation framework, spillpoint location, and closure categories (primary/secondary)
Example 3: Interpretation Scenario Documentation
- Input: Ambiguous reflection patterns in a salt-adjacent zone with multiple possible structural interpretations
- Output: Three competing interpretation models with assumptions listed, supporting seismic evidence, and implications for trap definition and drilling risk

You can perform comprehensive wellbore hydraulics analysis by inputting well geometry, fluid properties, and operational parameters. Claude calculates pressure drops across open hole and cased hole sections, determines equivalent circulating density (ECD) for narrow margin windows, identifies flow regime transitions, and provides optimization recommendations that balance ROP, hole cleaning, and well control margins. This enables you to validate designs, troubleshoot pressure anomalies, and make data-driven adjustments to flow rates and drilling fluid specifications before issues impact operations.

You can analyze geochemical analytical data to characterize petroleum source rocks and quantify their hydrocarbon generation potential. This skill guides you through interpreting Rock-Eval pyrolysis parameters (S1, S2, S3, Tmax), assessing thermal maturity using vitrinite reflectance and Tmax correlations, classifying kerogen types (I-IV), calculating transformation ratios, and evaluating depositional environments to construct petroleum systems models and manage exploration risk.

You can process cuttings samples, core descriptions, wireline logs, and offset well data simultaneously to identify formation boundaries, detect unexpected lithology, and generate actionable drilling recommendations within 15–30 minutes. The skill cross-validates disparate data sources to confirm formation picks, mitigates drilling delays that cost $1M+/day on deepwater rigs, and produces audit-compliant documentation of stratigraphic decisions made in real time.

You can conduct systematic hazard identification across operational zones, quantify exposure severity using evidence-based risk matrices, and develop hierarchical control strategies with realistic implementation timelines. This skill helps you document defensible assessments that satisfy regulatory requirements (OSHA, API, IMCA) and support informed decision-making for health protection measures.

You can analyze pressure buildup and drawdown test data to identify flow regimes, apply type curve matching techniques to estimate reservoir properties, and conduct material balance studies to quantify original oil/gas in place (OOIP/OGIP). Claude helps you evaluate pressure support mechanisms, generate production forecasts under different depletion scenarios, and assess reserve uncertainty from pressure interpretation data.

You can systematically interpret sedimentary facies from core descriptions, wireline logs, and outcrop data to build coherent paleoenvironmental models. This skill helps you classify lithofacies and ichnofacies, recognize recurring depositional patterns, correlate stratigraphic intervals across multiple wells, and predict reservoir quality and geometry based on depositional systems. You'll move beyond simple lithologic logging to derive interpretations that directly support exploration risking, play fairway mapping, and field development planning.

You can decompose seismic interpretation into discrete analysis phases—structural identification, stratigraphic correlation, fault characterization, seal integrity evaluation, and source-to-trap geometry validation. Claude generates ranked prospect summaries with explicit confidence levels tied to seismic data quality, regional analogs, and pressure regime consistency, giving you documented rationale for go/no-go decisions and resource allocation across exploration blocks.

You can systematically analyze formation pressure measurements, buildup/drawdown test data, and long-term monitoring records to diagnose underlying reservoir behavior. This skill helps you identify depletion trends, detect faulting or sealing boundaries, quantify aquifer support, track fluid contact movement, and reveal wellbore communication patterns—transforming raw pressure data into strategic guidance for drilling locations, completion design, and production operations.
