Seismic Interpretation & Structural Analysis for Exploration
Interpret seismic data and map subsurface structures for hydrocarbon prospect definition
What You Can Do
You can systematically interpret seismic horizons, define trap geometries, analyze fault-seal integrity, and evaluate hydrocarbon systems risk. The skill helps you translate complex seismic data into documented prospect definitions with depth-converted volumes, cross-validate interpretation scenarios against well-seismic ties, and build risk-weighted volumetric estimates to support drilling decisions and portfolio prioritization.
Features
map multiple seismic reflectors and fault geometries across 2D/3D surveys to establish structural framework
delineate anticlines, fault-bounded closures, and stratigraphic traps with closure depth and spill point analysis
analyze amplitude, impedance, and coherence attribute maps to identify seismic signatures of hydrocarbons
convert two-way travel time to true depth and calculate trap volumes with depth uncertainty ranges
evaluate fault throw, dip, and juxtaposition to determine seal integrity across critical hydrocarbon contacts
validate interpretations against well log data and adjust velocity models to improve structural accuracy
systematically evaluate trap definition, seal, source, and migration risk across multiple scenarios
generate prospect summaries with interpretive rationale, cross-sections, and decision support for presentations
Example Output
Example 1: Anticline Trap Definition
- Input: Seismic inline 450, horizon pick at 2,840 ms, well-log velocity model
- Output: Mapped anticline closure with crest depth of 3,150 m, spill depth 3,185 m, closure area ~45 km², structural relief ~350 m. Risk assessment: trap geometry confidence 85%, seal integrity across Shale-X at top structure 92%.
Example 2: Fault-Bounded Trap Analysis
- Input: 3D seismic cube, fault surface, throw variation along dip
- Output: Fault throw summary (max 280 m, min 120 m), juxtaposition analysis showing sand-on-sand contact in hangingwall, shale seal in footwall at critical contact. Seal risk rating: 78% (moderate—dependent on fault rock properties).
Example 3: DHI Interpretation
- Input: Amplitude map, impedance inversion, well calibration
- Output: Bright-spot anomaly colocation with structural closure, -10 dB amplitude enhancement vs. background, low-impedance zone consistent with hydrocarbon saturation. DHI confidence: 70% (supported by seismic signature, minor structural complexity reduces confidence).

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.

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.

Rapidly assess incident severity and classify emergency levels based on your operational parameters, automatically activate appropriate incident command structures and response teams, and generate real-time communications to regulatory agencies, corporate leadership, and stakeholders. You'll coordinate response activities across operations, medical, environmental, and communications teams while maintaining clear decision logs and identifying critical information gaps during active incidents.
Guide your team through comprehensive Process Hazard Analysis (PHA) using HAZOP, What-If Analysis, and LOPA frameworks to identify potential failures, assess their consequences, and develop defensible safeguard hierarchies. This skill helps you document hazard evaluations with full audit trails, prioritize process safety improvements, and ensure compliance with regulatory requirements before incidents occur.
