Seismic NMO Correction Calculator

Normal-moveout hyperbola t(x)^2 = t0^2 + x^2/V^2 for a horizontal reflector, with zero-offset time t0 in seconds, source-receiver offset x in meters and velocity in meters per second.

Description

Normal-moveout hyperbola t(x)^2 = t0^2 + x^2/V^2 for a horizontal reflector, with zero-offset time t0 in seconds, source-receiver offset x in meters and velocity in meters per second.

Seismic NMO Correction Calculator: Normal-moveout hyperbola t(x)^2 = t0^2 + x^2/V^2 for a horizontal reflector, with zero-offset time t0 in seconds, source-receiver offset x in meters and velocity in meters per second.

When to use Seismic NMO Correction

Use this geological calculation for a transparent first-pass interpretation of measured rock, soil, fluid, well, stratigraphic, isotopic, geophysical, or seismic data under an explicitly selected model.

t0
Zero-offset two-way time in seconds.
x
Source-receiver offset in meters.
V
Moveout (RMS/stack) velocity in meters per second.

How Seismic NMO Correction works

Normal-moveout hyperbola t(x)^2 = t0^2 + x^2/V^2 for a horizontal reflector, with zero-offset time t0 in seconds, source-receiver offset x in meters and velocity in meters per second. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.1

t(x)
Reflected arrival time at the given offset in seconds.
NMO
Normal-moveout correction t(x) - t0 in seconds.

Limitations and assumptions

  • Seismic magnitudes, moments, travel times, velocities, resolution, and energy depend on instrument correction, Earth model, phase picking, geometry, attenuation, radiation pattern, bandwidth, and calibration range. Magnitude scales are not universally interchangeable.
  • Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Alternative or Complementary approaches

Compare independent measurements and models, retain units and analytical metadata, propagate uncertainty, and validate interpretations against logs, cores, maps, laboratory data, or field observations.
