We have completed the drilling of the ninth well in the Tupi area, in the Santos Basin pre-salt cluster, and confirmed the field's light oil and natural gas recovery potential, which has been estimated between 5 and 8 billion barrels of oil equivalent. This well, in addition to proving that the oil accumulation extends to the far south of the Assessment Plan area, also showed that the oil-bearing reservoir is about 130 meters thick, reducing hydrocarbon volume estimate uncertainties for the area.
The results attained by drilling the ninth well defined, among other things, the oil/water contact level in the reservoir, which indicated the greater thickness of the oil-bearing rock in this area, among the possibilities under study.
In addition to the large estimated recoverable volume, the Tupi oil has a density of 28o API, which indicates excellent commercial value. The declaration of commerciality for the field is scheduled for next December 31. Until then, two more delimitation wells will still be drilled.
The well, informally known as Tupi SW, was drilled in water depths of 2,152 meters. It is located about 290 kilometers off the coast of the State of Rio de Janeiro.
The productivity of the well's pre-salt layer reservoirs, now completed, will be assessed by means of formation tests scheduled for the coming months. Once the expected yield has been confirmed, the consortium will analyze the installation, in the southern area of Tupi, of one of the first standardized platform vessels that are being designed to operate in the Santos Basin pre-salt.
