Teepee technology applied to design acquisition of seismic P-waves, Part 2―3D land example

摘要

In part 1 of this three-part series, seis-mic subsurface illumination using the concept of "teepees" was introduced and described. This second installment presents a 3D land design example to demonstrate how the teepee optimizes seismic recording projects for cost and collecting data that will produce the desired imaging quality. Subsurface teepees are the building blocks of the 3D survey. If the bin-to-bin characteristics of fold, azimuth, and offset are to be uniform (critical to the interpretation process), each subsurface teepee must be of equal size, shape, and resolution. To ensure uniformity with fold, the teepee overlap in each dimension must be an integer multiple of the respective teepee dimension.
