Abstract
Embodiments presented provide for a fully automated method of high-resolution interval velocity estimation for vertical seismic profile-type data.
Claims20
A method, comprising:
- lowering one or more sensors into a wellbore;
- performing a seismic test using one or more seismic sources;
- obtaining particle velocity data from the seismic test from at least one geological stratum in a field location using the one or more sensors;
- obtaining strain data from the seismic test from the at least one geological stratum in the field location using the one or more sensors;
- performing a first peak-to-peak amplitude analysis for the particle velocity data at the at least one geological stratum for at least one of a direct P wave, a reflected P wave, a direct S wave, or a reflected S wave;
- performing a second peak-to-peak amplitude analysis for the strain data at the at least one geological stratum for the at least one of the direct P wave, the reflected P wave, the direct S wave, or the reflected S wave;
- and
- estimating a velocity of waves in the at least one geological stratum based upon the first peak-to-peak amplitude analysis for the particle velocity data and the second peak-to-peak amplitude analysis for the strain data.
