Typical Vertical Resolution

This document presents a detailed comparison of seismic resolution characteristics for shallow and deep events. For shallow events, with a velocity of 2000 m/s and a center frequency of 50 Hz, the resolution limit is calculated to be 10 meters. In contrast, deep events with a velocity of 3000 m/s and a center frequency of 20 Hz yield a resolution limit of 37.5 meters. Understanding these parameters is essential for accurate seismic data interpretation and is critical for fields such as geophysics and exploration geology. Data provided courtesy of ExxonMobil.

  1. Typical Vertical Resolution • Shallow Event • Velocity = 2000 Meters / sec • Pulse: • Center Frequency = 50 Hz • Period = 1 / 50 = .020 sec • Wavelength = .020 x 2000 = 40 Meters • Limit of resolution = 40 /4 = 10 Meters • Deep Event • Velocity = 3000 Meters / sec • Pulse: • Center Frequency = 20 Hz • Period = 1 / 20 = .050 sec • Wavelength = .050 x 3000 = 150 Meters • Limit of resolution = 150 / 4 = 37.5 Meters Courtesy of ExxonMobil
