Refracted P-wave
Fig. 3: Rays of refracted P-wave (history file sal-ray1.h).
Reflected P-wave
Fig. 4: Rays of P-wave reflected from the salt top interface (history file sal-ray1.h).
Reflected P-wave
Fig. 5: Rays of P-wave reflected from the salt bottom interface. Salt top interface is partially transparent (history file sal-ray1.h).
Reflected P-wave
Fig. 6: Rays of P-wave reflected from the bottom flat interface. Geopressure horizon is partially transparent (history file sal-ray1.h).
Reflected P-wave
Fig. 7: Rays of P-wave reflected from the salt bottom interface. Shot is located in the well above the salt in the depth of 900m. The salt bottom interface is partially transparent (history file sal-rwe1.h).
Multiply reflected P-wave
Fig. 8: Rays of P-wave multiply reflected from the bottom of the salt and from the bottom flat interface. The shot is located in the well, below the salt, in the depth of 2300m (history file sal-rwe2.h).
Reflected P-wave
Fig. 9: Rays of the P-wave reflected from the bottom flat interface. The model is cut by GOCAD slicer (history file sal-mapx.h).
