Key points
- Undertaken with in-country support of ResLab Solintec do Brasil, with Access to cores & samples in Rio were kindly provided by the ANP & Petrobras.
- Clastic and carbonate reservoirs characterised in the Albacora, Caratinga, Corvina, Pampo & Roncador Fields, presented here as field-scale integrated technical reports.
- 1,318m of core described at a 1:50 scale, with 112 samples analysed petrographically, 80 SEM and quantitative XRD analyses and 125 samples with new quantitative biostratigraphic analyses – all tied to 16 2D seismic lines.
This study presents the results of an integrated sedimentological, ichnological, stratigraphical and reservoir quality appraisal of five fields from the Campos Basin, Brazil. The field areas under investigation include Albacora, Caratinga, Corvina, Pampo and Roncador. The project investigates the gross structural setting, stratigraphic development and sedimentary style of reservoir-scale building blocks together with primary and secondary controls on reservoir quality. A total of 1315.86m of detailed core logging has been undertaken together with new biostratigraphical analyses, petrographic analysis including SEM/XRD and conventional core analysis. The aim of the study is to provide a comprehensive database of analogue data from these fields which is of specific relevance to exploration and operating companies assessing the prospectivity and commerciality of existing oil and gas fields and frontier exploration acreage within the Campos Basin. This data has been compiled to be an integral part of the assessment of geotechnical risk for current and future projects in the Campos Basin.
Deliverables
- Data on the reservoir interval from 25 wells from the Albacora, Caratinga, Corvina, Pampo and Roncador Fields, Campos Basin.
- Stratigraphic interpretation of the reservoir interval for all wells.
- Reservoir sequence stratigraphy and depositional model for each of the fields.
- Calibration to seismic based on released 2D data.
- Detailed core descriptions at 1:50 scale for the cored intervals (total 1315.86 m).
- Reservoir quality study including petrographic descriptions of 112 thin sections (plus SEM/XRD on select samples) documenting primary and secondary mineralology and quantification of primary depositional and secondary diagenetic factors.
- Conventional core analysis data on a total of 389 core plugs.
- Set of representative core photographs illustrating sedimentological, ichnological and tectonic/diagenetic features.
