PETROBRAS’ oil production at the pre-salt layer of the Santos and Campos basins has passed its daily production record of 470,000 barrels of oil per day.
“The average productivity per well from the Santos basin’s Pre-Salt Layer reached 28,000 bpd, representing an increase of almost 30 per cent since February 2013, when the daily production record of 300,000 bpd was set,” Petrobras said.
Petrobras said the result, which came from its 24 wells in the area, was largely due to well 7-LL-22D-RJS coming into operation on 9 May.
“The new well, which currently generates a f low of 31,000 bpd, is connected to the FPSO Cidade de Paraty platform ship, located in the Lula field, using a Buoyancy Supported Riser (BSR),” the company said.
This is the company’s third well to be connected using BSR technology, allowing the production pipeline to be suspended from a submerged buoy, as well as being the first to be connected to the FPSO Cidade de Paraty.
The first two BSR connected wells, connecting to the FPSO Cidade de São Paulo in the Sapinhoá field, have average outputs of about 36,000 bpd and 35,000 bpd respectively.
The FPSO Cidade de São Paulo currently produces around 100,000 bpd, from three wells, while the output of the FPSO Cidade de Paraty, stands at around 60,000 bpd, from two wells.
Petrobras said it would connect a series of new wells to the FPSOs using BSRs over the coming months, reaching the maximum capacity for this type of platform – of 120,000 bpd – in the third quarter of this year.
The Lula field is operated Petrobras (65%), in partnership with BG E&P Brasil (25%) and Petrogal Brasil (10%), while the Sapinhoá field is operated by Petrobras (45%), in partnership with BG E&P Brasil (30%) and Repsol Sinopec Brasil (25%).
