Deep Panuke Project Description - Encana

Potential Radioactive Components: The presence of radon, a Naturally Occurring Radioactive Material(NORM), was measured during well testing by an RDA 200 Radon Detector. Deep Panuke raw gascontains very low levels of radon (Rn), in the range of 50-100 Bq/m 3 , equivalent to 1.4-2.7 pCi/Litre(Conversion factor: 1Bq = 27.027 pCi).The following sections describe the process by which EnCana proposes to develop this reservoir andproduce market-ready gas.2.2 Project Infrastructure ComponentsThe main Project infrastructure components include a mobile offshore production unit (MOPU), subseawells and flowlines, and a subsea pipeline to transport sales product to either Goldboro, NS (M&NPOption) or SOEP 660 mm [26 inch] pipeline tie-in (SOEP Subsea Option).A rendering of the proposed layout is presented in Figure 2.2.2.2.1 Mobile Offshore Production Unit (MOPU)The MOPU comprises the hull and topsides facilities. The hull includes all facilities and equipment thatwould normally be supplied with a mobile jack-up unit including jacking systems, legs, foundations,accommodations, helideck and utilities. The topsides facility will include all equipment required forprocessing hydrocarbon fluids from the reservoir. The topsides equipment will generally be located on topof the main deck but may also include equipment located within the hull, such as the central control room.The topsides facility will contain processing equipment to separate, measure, dehydrate, and sweeten theraw gas. Acid gas and water handling equipment will also be installed on the MOPU. Hydrocarbondew pointing will be required for the M&NP Option and the condensate will be used as the primary fuelfor power generation and compression. Currently, it is estimated that there will be no surpluscondensate produced beyond fuel usage; however, in the event that condensate must be injected, it willbe injected down-hole with the acid gas stream. For the SOEP Subsea Option, condensate separatedfrom the gas will be dehydrated, sweetened, and recombined with the export gas for delivery to the tie-infor the SOEP Subsea Option. The production facility is designed to export 8.5 x 10 6 m 3 /d [300MMscfd].Deep Panuke Volume 4 (Environmental Assessment Report)• November 2006 2-3
