Environment Report 2014

All the subsea wells capable of unassisted flow in the 2014 survey can flow gas. The gas flow rates are shown in Figure 26. Meanwhile, 94 per cent (509) can flow both oil and gas, the oil flow rates for which are shown in Figure 27. The majority (52 per cent) of subsea wells that are capable of unassisted gas flow can flow between one and five million standard cubic feet per day (MMSCFD). Of the 543 wells capable of unassisted flow, six per cent can freely flow more than 50 MMSCFD.
