The Reconcavo Basin was the first producer basin of hydrocarbons in Brazil and it was the largest oil producer during 4 decades. That basin has its origin related to extensional efforts acted in Gondwana during the Mesozoic period, and has high index of recoverable oil. This paper aims to present the complete processing flow of the seismic line 2D 26-RL-1993 located in the Northeast compartment of the Reconcavo Basin. The processing flow was applied the following steps: geometry, editing, static correction, velocity analysis, normal moveout correction (NMO), stacking, migration as well as several techniques of filtering and amplitude corrections. We show that the filtering methods to increase the signal to noise ration are crucial to obtaining of a seismic section of good quality.
