| 20100265793 | Methods for Optimizing Offset Distribution of Cross Spread 3-D Seismic Surveys Using Variable Shot Line Length - A method for acquiring three-dimensional seismic data for sub-surface geologic features wherein a seismic source array is moved along a survey pattern having a plurality of source lines of unequal lengths that are substantially parallel to each other and intersect a receiver line. The survey pattern can be repeated in an overlapping and interleaved fashion to survey a larger area. | 10-21-2010 |
