Пожалуйста, помогите перевести. Это в микросейсмическом анализе.

Выражение встречается в следующем контексте:
Calibration
Two stringshots were performed to calibrate the velocity to known locations.
Stringshot 1: 60ft of 80grain, 10499ft TVD
Stringshot 2: 80ft of 80grain, 8835ft TVD

The stringshots are depth corrected by applying a scalar shift to the velocity model. The velocities were increased by 7% to position both stringshots at the correct depths.

Statics were then computed on the moveout corrected stringshots and subsequently applied to all traces in processing.
Заранее всем большое спасибо!!!
