The fourth well drilled in the Jupiter area is located 296km off the coast of Rio de Janeiro at 2183m water depth. It sits 8km southwest of the original discovery well.
The discovery was made following drilling operations at well 3-BRSA-1246-RJS (3-RJS-732), informally known as Apollonia. Petrobras found a hydrocarbon column measuring apprxomiately 313m, and 87m thick, with rocks showing good porosity and permeability.
Drilling is still in progress and is expected to reach a final depth of approximately 5700m.
Samples collected from the well have confirmed fluids similar to those found in pioneer Jupiter well 1-RJS-652A and at both extension wells drilled so far, which have confirmed a sizeable reservoir of natural gas, CO2, condensate and oil.
In October 2013, Petrobras completed drilling of the third Jupiter well, Bracuhy. The project confirmed a hydrocarbon column of approximately 160m, and measured 100m thick, which contained rocks of good porosity and permeability. Bracuhy is 267km off the coast of Rio de Janeiro in 2251m water depth.
Earlier this month, Petrobras announced drilling began on the first exploration well on the Libra pre-salt area in the Santos basin. Libra is estimated to contain 8-12 billion boe. The well is being drilled using the NS-36 Schahin Cerrado drillship.
Petrobras is the operator of the consortium with an 80% interest with partner Petrogal Brasil (20%). The joint venture will proceed with the activities provided for in the discovery evaluation plan approved by Brazil’s National Petroleum, Natural Gas and Biofuels Agency.
