Quiz, Part 9: Capstone Case Studies

Part 10, Self-Assessment Quizzes

Learning objectives

Self-test mastery of Part 9: 6 real-field capstones (Girassol, Valhall, Thunder Horse, Wolfcamp, Tupi, Sleipner)
Identify the canonical workflow + diagnostic signature for each capstone’s exemplary application
Re-run with fresh draws to consolidate field-by-field knowledge

Self-assessment quiz drawn from a 25-question bank covering all six capstone case studies of Part 9: Capstone Case Studies. The quiz randomly selects 15 questions per session.

Each capstone is anchored on a REAL FIELD with publicly-documented results. The questions test recognition + interpretation of each field’s canonical workflow + diagnostic signatures, the kind of pattern-matching senior interpreters use when they encounter analog plays.

What this quiz tests

Section 9.1 Girassol (Angola, deepwater turbidite QI): RMS amplitude, AVO fluid factor, net sand from impedance, top-reservoir depth and closures, the three-leg screen and a time-lapse monitor (4 Q)
Section 9.2 Valhall (North Sea chalk 4D compaction): the chalk compacts, the seabed sinks and the overburden stretches and slows, so the top of the chalk arrives later; time shifts from 1982 to 2020 (4 Q)
Section 9.3 Thunder Horse (Gulf of Mexico subsalt): light and position beneath salt, from Kirchhoff with no salt through a smoothed salt model, reverse-time migration and an FWI model to inversion (4 Q)
Section 9.4 Wolfcamp (Permian shale completion): brittleness against least horizontal stress, fracture height from the stress contrast and the net pressure, what a band-limited inversion resolves, and lateral azimuth from the greatest horizontal stress (5 Q)
Section 9.5 Tupi, formerly Lula (Brazil pre-salt carbonate): pore shape moves velocity as far as porosity does, Gassmann and its limits, and the reflection at the base of the salt (4 Q)
Section 9.6 Sleipner (Norway CCS): the CO₂ in nine thin layers, the push-down beneath them, the mixing law and tuning, survey by survey from 1994 to 2016 (4 Q)

If you can pass this quiz reliably, you have the field-recognition vocabulary that working senior interpreters use to PATTERN-MATCH new prospects against analog real fields, one of the most valuable skills in modern subsurface exploration.
