The New Deepwater Oil and Gas Province in Brazil: Flow Assurance and Artificial Lift: Innovations for Jubarte Heavy Oil

Abstract

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractThe Jubarte field, in the Campos Basin, Brazil, was discovered in January 2001. It is located about 80 km offshore from the State of Espírito Santo, under water depths between 1,000 and 1,500 m, containing oil of 17 °API and viscosity of 14 cP at reservoir conditions. This work presents a review of the artificial lift and flow assurance aspects faced by PETROBRAS in the exploitation of Jubarte heavy oil, starting from the features of the Pilot Phase. It details all the challenges posed and innovations proposed and implemented for Phase 1 field development, as well as expectations for the subsequent Phase 2.

Subsea ESP Skid Production System for Jubarte Field

“…Whereas P-57 wells were a complement to Jubarte Phase 2 development, which already had 15 other producers using ESPs in vertical pumping modules known as MOBO 1 (Colodette et al 2007), P-58 is a new platform that produces from presalt and post-salt reservoirs (Tarcha et al 2015).

Modeling of gas–liquid separation inside a slightly inclined annular duct

“…One example is the ESP Skid, 2 , a Petrobras project for better profitability, that significantly lowers cash flow implications during any period of either intervention or stopped production due to pump failure. The ESP Skid is housed in the subsea downstream the Christmas tree and slightly inclined horizontally (Details of such equipment can be found in Colodette et al 3 ; Teixeira et al 4 ; Costa et al 5 ; Tarcha et al 6,7 ; Vieira, 8 ; Vieira et al 9 and Vieira et al 10 ).…”
