Comments
The Pazflor project is located in Block 17, in deepwater offshore Angola.  The development area is located approximately 40km East of the existing Dalia FPSO and 150km from shore.

The project will target development of hydrocarbons in two independent reservoir structures;
-Miocene reservoirs, in 600m to 900m water depth, containing heavy oil to be recovered using subsea gas/liquid separation and liquid boosting. 
-Oligocene reservoirs, in 1,000 to 1,200m water depth, containing light oil to be developed with a production loop including riser bottom gas lift.

The overall development consists currently of 49 subsea wells connected via subsea production, injection lines and risers to a spread moored FPSO. The topside control system is designed to accommodate further 21 wells and a fourth subsea separation unit.
