Survey Design Fold Count CMP Binning Summary
Nominal 2-D end-on acquisition fold N·Δr/(2·Δs) and CMP interval Δr/2 for a regular source/receiver grid; actual edge fold and irregular geometry require explicit trace counting.
Description
Nominal 2-D end-on acquisition fold N·Δr/(2·Δs) and CMP interval Δr/2 for a regular source/receiver grid; actual edge fold and irregular geometry require explicit trace counting.
Survey Design Fold Count CMP Binning Summary is a focused tool for the following task. Nominal 2-D end-on acquisition fold N·Δr/(2·Δs) and CMP interval Δr/2 for a regular source/receiver grid; actual edge fold and irregular geometry require explicit trace counting. It reports fold, bin from the values you provide rather than inventing measurements, coefficients, or professional judgment that are not part of the input.

- N_r
- Required integer. Active receivers per shot.
- Δr (m)
- Required number in m. Receiver group interval.
- Δs (m)
- Required number in m. Shot-point interval.

How Survey Design Fold Count CMP Binning Summary works
Nominal 2-D end-on acquisition fold N·Δr/(2·Δs) and CMP interval Δr/2 for a regular source/receiver grid; actual edge fold and irregular geometry require explicit trace counting. Inputs are interpreted exactly in the displayed units and the calculation returns the following fields without presentation rounding.
- fold
- Returned number. Nominal fold-of-coverage.
- bin (m)
- Returned number in m. CMP interval for the assumed regular grid.
Limitations and assumptions
- Earth structure, source geometry, path effects, site response, instrument response, catalog completeness, uncertainty, and the fitted range can dominate the accuracy of simplified seismic calculations.
- N_r must be at least 2.
- Δr must be at least 0.
- Δs must be at least 0.
- Use finite inputs in the displayed units, preserve source measurements and assumptions, and independently verify consequential decisions.
Alternative or Complementary approaches
For analysis or hazard decisions, retain uncertainty and provenance and compare the result with waveform processing, calibrated regional models, and guidance from qualified seismologists or the responsible agency.
