The well, designated as 3-BRSA-865A-RJS (3-RJS-677A), was drilled at a water depth of 2 139m, approximately 275km off the coast of Rio de Janeiro state and 11km northwest of the original Tupi discovery well.
Oil samples taken during wireline tests in the well confirmed the presence of a light oil accumulation (approximately 28 degrees API).
The well encountered a 90m reservoir section on the western flank of Tupi helping further delineate the size and quality of the field.
Further testing will now be conducted on the 3-RJS-677A well and if those results confirm the initial productivity data, BG Group and its partners will consider the allocation of a floating production, storage and offloading vessel to the west area of Tupi.
BG Group has a 25% interest in the Tupi, Iracema and Iara discoveries in the BM-S-11 concession.
