Design a Seismic Survey
Fold, offset, azimuth, and the judgment to trade them. From the physics of sources and receivers to a geometry you can defend, on land or at sea, with the QC to prove the field delivered it.
You can specify sources, receivers, and a 3D geometry for a stated imaging objective, defend the fold-offset-azimuth trade-offs in review, and run the field QC that catches problems while they are still cheap.
The physics you point at the ground
Every design rule in this path is Huygens plus the reflection coefficient wearing work clothes.
A source radiates where physics says, not where you wish; array theory is how you steer what you cannot aim.
Spatial aliasing is the one acquisition mistake no processor can ever undo, and the noise taxonomy tells you what you are sampling against.
Reciprocity halves your design problem, and attenuation decides how much bandwidth survives to the target.
Sources
Charge size, depth, and coupling are the oldest design variables in the business and still the most unforgiving.
The two workhorse sources: sweeps and their distortions on land, bubbles and ghosts at sea; both are design problems before they are equipment.
The ghost notch sets your usable bandwidth and simultaneous shooting sets your cost; both are decided at the design desk.
Receivers
Coil-magnet physics versus accelerometers is a real trade with real spectra; know what your sensor cannot hear.
Pressure versus motion, and the 3C/4C sensors that catch the converted waves single components throw away.
Group-forming, fiber, and the unglamorous truth that coupling quality decides more surveys than sensor choice does.
Geometry, the heart of design
These four statistics are the currency every survey is priced in; learn to read a fold map like a balance sheet.
The bin is where sampling theory meets money: too big aliases the dips you were paid to image, too small buys nothing.
Inline and crossline templates, salvos, and roll-alongs are the vocabulary the crew actually executes; design in their words.
Migration aperture sets the survey bigger than the target, and the end-to-end walkthrough is where every rule earns its place.
Marine practice
Towing kilometers of cable behind a moving vessel is its own physics; the streamer spread is a design object, not a given.
Dual-sensor and over-under designs buy back the ghost notch, and feathering quietly rewrites your azimuth plan every hour.
Nodes on the seabed and WAZ/RAZ/FAZ towing are how marine surveys buy the azimuths that subsalt targets demand.
Land practice
Vibroseis fleets and nodal layouts live or die on logistics; the design must survive contact with the terrain.
Ground roll and cultural noise shape the geometry: orthogonal, brick, zigzag, and slanted layouts each answer a different noise question.
The near surface will wreck your image unless the survey records what is needed to solve it; statics start at the design desk.
QC in the field
A bad shot caught today costs a reshoot; caught in the processing center it costs the image.
Source signatures, first breaks, and positioning are the three quiet logs that decide whether the processors inherit data or excuses.
The design desk
A real wide-azimuth design problem, end to end, with the budget and the subsalt target both watching.
The whole discipline compressed onto one card you can carry into a bid review.
