Course Content

The lacustrine rocks of the Pre-Salt offshore Santos basin in Brazil belong to two formations deposited during the Cretaceous period. The basal unit, the Itapema Formation, consists primarily of bioclastic lacustrine deposits composed of bivalve rudstones and form important reservoirs mainly in Buzios and Mero fields. The overlying Barra Velha Formation, located just below the salt layer, is predominantly composed of carbonate sediments of chemical origin and represent the main producing unit for several pre-salt accumulations in the basin.

This two-day study of the pre-salt cores aims to present and discuss the geological succession of the Itapema and Barra Velha formations in Buzios, Mero and Tupi fields, located in Santos Basin. The selected cores will provide a didactic overview of the main facies, facies associations and interpreted depositional systems.

Participants will have the opportunity to examine and discuss the Aptian cores from Itapema and Barra Velha formations in these oil fields, focusing on facies analysis, processes, stacking patterns and interpretation of depositional systems. Stratigraphic surfaces (Unconformities) observed in both cores and available seismic data and the records of lake-level variation will be discussed. The recognition of the Pre-Alagoas Regional Unconformity (DPA) at Búzios, Mero and Tupi fields and discussions on distinct characteristics of each of these fields will be covered during these two full days.

By the end of the core-workshop, participants will have a comprehensive understanding of the pre-salt reservoirs at three of the most prolific areas offshore Santos basin in Brazil.

Who Should Attend: Geologists and Geophysicists involved in reservoir or exploration interpretation.

Prerequisites: Basic knowledge of Sedimentology and Stratigraphy

Instructor(s)

Carlos is a geologist, holding a degree from UFMG (Federal University of Minas Gerais), a master's in geology with an emphasis on sedimentary petrology from UFOP (Federal University of Ouro Preto), and a PhD from the University of Leeds, UK, specializing in deep marine depositional systems (with a case history on the Amazon Fan). WorkExperience: He joined Petrobras in 1993, where he worked in the Sedimentology and Stratigraphy Department at the Research Centre. During this time, he coordinated and participated in numerous sedimentology/stratigraphy projects and managed the Scanning Electron Microscopy Laboratory from 2000 to worked in Exploration, coordinating Petrobras' Rock Laboratories. A consultant specializing in depositional systems and diagenesis of he is currently leading research and develooment prolects in sedimentology and stratigraphy at the Búzios Field in the Santos Basin.

Caroline is a geologist, holding a degree from UFRJ (Federal University of Rio de Janeiro), a master's in geology with an emphasis on sedimentary petrology and diagenesis from pre-salt rift deposits of Santos Basin at UFRGS (Federal University of Rio Grande do Sul). WorkExperience: She joined Petrobras in 2011, since then she has been working in the Sedimentology and Stratigraphy Department at the Research Center. During this time, she coordinated and participated in numerous sedimentology/stratigraphy projects. She is an expert in sedimentology, petrology and diagenesis of pre-salt carbonate rocks, giving classes to company professionals on these topics and integrating research teams dedicated mainly to Buzios Field in Santos Basin.

Francisco holds a degree in Geology from the Federal University of Rio de Janeiro (1986) and a PhD in Carbonates (2007) from the Rosenstiel School of Marine and Atmospheric Science at the University of Miami, USA. Work Experience: He is a master geologist and senior consultant at Petrobras and has in the company for past 37 years dedicating himself to the sedimentology and stratigraphy focused on correlation and rock data to PETROBRAS extensive carbonate consulting and technical support for prospect generation/evaluation and production development of sub- and post-salt plays and reservoirs within the E&P. He is also an active fieldtrip leader and instructor on several field seminars and short courses promoted by Petrobras.

Luci holds a degree in Geology from Federal University of Rio Grande do Sul (1982) and a master’s degree in Geology at the same institution in 1984. Her PhD degree in Sequence Stratigraphy (1996) from the Federal University of Rio Grande do Sul focused on stratigraphic analysis and studies on gravity flow and geometry of the rift deposits of the Maceió and Poção formations at Sergipe-Alagoas Basin. Work Experience: From 1984 to 1986, she served as a professor of Sedimentology and Petrography at University Vale Rio dos Sinos - UNISINOS in Brazil. She joined Petrobras Research Center - CENPES in 1987. Along her career, she worked as a geologist until 2001, before working as a technical consultant for 11 years at CENPES. From 2012 to 2019, Luci worked as a master consultant on sedimentology and stratigraphy of post-salt turbidites and pre-salt carbonate reservoirs for the E&P. Additionally, she acted as a field guide leader for several significant geological regions in Brazil and overseas. Her current assignment is a researcher at UNISINOS dealing with the pre-salt rocks.
