An efficient first arrival picking procedure for marine streamer data
Picking first breaks is a tedious and time-consuming process. We suggest a procedure for an efficient manual first arrival picking of marine towed-streamer data. The procedure contains three methods: we reduce the total number of manual picks by skipping shots and interpolating picks of each shot gather, reusing previous picks, and sorting three-dimensional (3D) shot gathers using offset. Two-dimensional and 3D simulations demonstrate that we can accelerate the picking process 11–117 times compared to that of a complete picking method. Although the efficiency varies depending on the data, the suggested procedure can save considerable manpower while maintaining the accuracy of manual picking.
