4.5.3 Marine Support VesselsHusky Oil proposes to charter existing marine support vessels from existing contractors for resupplyservices and ice management functions.4.5.4 Drilling ServicesOne or more semi-submersible drilling units will be used throughout the life of the field for drilling, reenteringand completing wells. These units will be chartered.The unit(s) will be moored at each well location supported by onboard chain and anchors. Marinesupport vessels, with anchor-handling capability, will be used to deploy and retrieve anchors inconjunction with rig anchor handling equipment.4.6 Development Drilling and Well CompletionsSince the discovery in 1984 of the White Rose field, with the drilling of the N-22 well, eight additionaldelineation wells have been drilled and suspended or abandoned.Up to approximately 18 to 25 wells will be required to develop the White Rose oil reservoir. Up to 10 to14 will be producing wells, six to eight will be water injection wells and two to three will be gasinjection wells.Initially, up to 10 wells will be drilled before field production begins. Plans are for wells to be drilled inclusters. Semi-submersible mobile offshore drilling units will be used to drill and complete these wellsbefore the arrival of the FPSO. The remainder will be drilled in parallel with producing operations tomeet the depletion plan objectives. The current plan is to start drilling several months after projectsanction is received.There were no significant operational problems encountered during the drilling of the White Rosedelineation wells, however, there is always some potential for problems and drilling hazards duringdrilling operations. The more typical problems that will be addressed within the well design andcontingency planning, include:• shallow gas;• hole instability;• formation pressure;• well control; and• differential sticking.White Rose DA Project Summary • January 2001 Page 60
The White Rose development well completions design is intended to maximize well productivity, whilemaintaining appropriate levels of risk and well integrity. Well performance modelling based on thereservoir properties of the discovery and delineation wells has been conducted for both flowing andartificial lift (gas lift) scenarios. The flowing well model suggests that initial oil rates of between 2,800and 4,200 m 3 /d are possible from horizontal development wells completed with 140-mm tubing. A wellwith average reservoir properties should flow at 3,600 m 3 /d of oil prior to water or gas breakthrough.Water associated with White Rose oil production is expected to increase over the life of thedevelopment. The flow modeling discussions above indicate that oil wells will require artificial liftwhen water cut exceeds 40 percent. Gas lift will be a readily available means of artificial lift with gascompression facilities required for the reinjection of produced gas. Gas lift also has advantages overother means of artificial lift because it has high reliability and efficiency.Prior to the start of production, all wells in a given glory hole will likely be batch completed after beingdrilled and temporarily suspended. It is assumed that at the end of batch drilling operations the wellswill be left with proper barriers in place and the vertical subsea trees will be fitted with back pressureplugs and external debris covers.4.7 Production OperationsHusky Oil will be the Operator of the White Rose oilfield on behalf of itself and Petro-Canada, its coventurer.The operation will be run from the Husky Oil office in St. John's, where the operationsmanagement will be located. The management and control of all offshore operations will be theresponsibility of the Offshore Installation Manager (OIM) who will be located on the FPSO. The OIMwill report to the Operations Manager.The on-shore organization will be structured to provide total support for all normal offshore operations,during the development and operations phases. The on-shore organization will include personnel withall the requisite skills, knowledge, and experience for ensuring competent support to the offshoreoperation, even in emergency situations. It will be focused on flexibility, efficiency and costeffectiveness. The permanent core of the on-shore organization team is expected to be 45 to 50 people.In addition, there will be further personnel on-shore in the following categories:• helicopter air and ground staff;• dockworkers and crane operators for supply vessel operations at the shorebase; and• crews for the supply and standby vessels.White Rose DA Project Summary • January 2001 Page 61
