Cachalote & Jubarte 2D4C

Description

The 4 line 2D program was designed to illuminate oil and disseminated gas in the tertiary Eocene and Oligocene reservoirs (~1,250 m beneath the sea floor) from northern Campos basin.

data deliverables (segy)

1.	Prestack time migration (P-wave, C-time & C-time converted to P-time)
2.	Near-, mid- and far- angle stacks, prestack time migrated (P-wave)
3.	Prestack time migrated gathers (P-wave without NMO, C-wave with cNMO applied)

other deliverables

1.	Migration and residual P-wave & C-wave velocity fields (ASCII format)
2.	Bin center data
3.	Acquisition and processing reports
