Jubarte Field

Description: The Jubarte Field it lies at a water depth of 1,300m in the northern Campos Basin in block BC-60.Discovered in January 2001, the field is owned and operated by Petrobras. The project was Petrobras's largest discovery since 1996, with oil reserves estimated at 600 million barrels.The field is a pre-salt area where oil and gas deposits lie under a layer of sal, making it difficult to tap the potential. In July 2002, Petrobras was awarded a license to run an extended well test in the field. A field development plan was devised consisting of three stages: pilot phase, phase I and phase II. The field's commercial feasibility, meanwhile, was confirmed in December 2002. Until January 2006 the well ESS-110 HPA produced 20,000b/d. The first oil in the pre-salt layer at the Jubarte field was produced in 2008. Phase I production started in late 2006 with the start of operations of FPSO JK (P-34), which had a processing capacity of up to 60,000 barrels. Phase I covered four producing wells. The Jubarte-4 horizontal well produces 15,000bpd of heavy oil. The other three wells contribute nominal capacities. With FPSO JK (P-34), the first pre-salt production resulted in production up to 18,000b/d in September 2008. Phase II production started in December 2010 through FPSO P-57. About 15 producing wells and seven injection wells were planned under this phase.
