4 DEVELOPMENT PLANDeveloping the White Rose <strong>oilfield</strong> will include:• design engineering of the selected production system;• procuring the goods and services required for the production system;• constructing or modifying various components of the production system;• installing and commissioning the production system at the White Rose site;• drilling and completing up to 18 to 25 wells (production, water injection and gas injection);• production, operation, maintenance and support services over the producing life of the field,designed for a 20-year life span; and• decommissioning and removing the production system from the White Rose site, and removingand/or abandoning the subsea infrastructure.4.1 Geology4.1.1 White Rose StratigraphyThe stratigraphic section penetrated by the wells drilled in the White Rose region contains Tertiary toUpper Jurassic age rocks. Of the formations penetrated, only the South Mara, Avalon, Eastern Shoalsand Hibernia sections have any reservoir-quality sandstones. The oldest rocks penetrated in the WhiteRose region are from the Voyager Formation in the White Rose N-22 well.The Egret Member is the main source rock for the hydrocarbons in the White Rose area and waspenetrated in the White Rose A-90, Archer K19 and Trave E-87 wells. Oil bearing, overpressuredsandstones, probably the Tempest Member were penetrated in the E-09 well.The Aptian-aged Avalon Formation is the primary reservoir in the White Rose field. In general, theAvalon is a marginal marine, shoreface succession through much of the field. The Avalon is dominatedby fine to very fine-grained sandstones, siltstones and shales, and ranges from 0 to 400 m in thickness.The main sandstone accumulations occur in the southeastern portion of the field with the E-09, L-08, A-17 and H-20 wells (South Avalon Pool) exhibiting thicknesses of up to 350 m of sandstone. The AvalonFormation is absent in the White Rose A-90 and Trave E-87 wells.White Rose DA Project Summary • January 2001 Page 47
