Quiz — Part 1: Foundations of Seismic
Learning objectives
- Self-test mastery of Part 1: cube basics, impedance + reflection coefficients, the convolutional model, processing, migration, time vs depth, 2D-vs-3D, and resolution
- Identify weak Part 1 topics before tackling the toolkit and structural-interpretation parts that follow
- Re-run with fresh draws to reinforce learning
Self-assessment quiz drawn from a 31-question bank covering all eight sections of Part 1 — Foundations of Seismic. The quiz randomly selects 15 questions per session. Re-running gives a fresh draw and exercises different concepts.
For each question, select your best answer and click Submit answer. The correct answer + a short rationale appear immediately. After all 15 questions, you’ll see a score summary and a list of any items you missed with the rationale for each.
What this quiz tests
- §1.0 Seismic cube basics: inlines, crosslines, time slices, RWB polarity convention
- §1.1 Acoustic impedance Z = ρ·Vp; reflection coefficient R = (Z₂−Z₁)/(Z₂+Z₁); polarity; brightness scale; energy conservation
- §1.2 The convolutional model s = r∗w + n; spike→wavelet; bandwidth and resolution; model assumptions
- §1.3 Processing pipeline: CMP, fold, NMO equation, RMS velocity, multiple attenuation, stacking
- §1.4 Migration: diffraction hyperbolas, smiles, time vs depth migration
- §1.5 Time vs depth: TWT formula, Dix equation, depth uncertainty propagation
- §1.6 2D vs 3D: sideswipe, misties, the four interpretation views, volume-centric mindset
- §1.7 λ/4 vertical resolution; tuning regime; Fresnel zone for lateral resolution
Score 90%+ and you have Part 1 well-internalized; below 75% and the misses listed at the end will tell you exactly which section to revisit. Run twice for fuller coverage of the bank.
