Step 1: Subsurface Bin Size & Spatial Sampling
Define equipment deployment intervals to establish horizontal image pixel resolution limits.
Geophysical Guidance Note: Due to midpoint reflection mechanics, the natural subsurface bin structure becomes exactly half of your input footprint values (RI/2 × SI/2).
Step 2: Fold of Coverage & Desired S/N Targets
Calculate how redundancy will attenuate ambient ground roll and environmental interference.
S/N Stacking Rule: Summing random wavefields improves signal profiles proportionally to √Fold. Choosing 48 Fold yields a statistical signal amplification factor of 6.93x over raw trace noise.
Step 3: Offsets (Deep Velocity & Shallow Gaps)
Optimize layout dimensions to safely image deep structures while eliminating shallow blind spots.
Maximum Minimum Offset Bounds: If line spreads cross too broadly, the mid-patch Largest Minimum Offset ($LM_{os}$) expands. Wide angles will be muted out during data processing, leaving zero near-surface traces.
Step 4: Temporal Sampling & Migration Aperture
Map target depth bounds, wave attributes, and signal collection times.

Ensure your field line boundaries extend by at least this radius amount past the edge of the reservoir target zone to safely capture dipping reflections.
