		Gadwall will be developed as a sub-sea tie back to the Kittiwake platformutilising a single producer/injector pair of wells.
		The expected producing life of the Gadwall oil field is approximately 10 years, with cumulative production of 6.6 million barrels of oil and 4.4 billion cubic feet of gas forecast to be recovered over that period, a total of 7.3 million barrels of oil equivalent.

		ABSTRACT - The Gadwall is a dabbling duck with a wide distribution that extends across Europe, Asia, and North America.
		We examined genetic variation using 658 bp of DNA from domains 1 and 2 of the mitochondrial control region of 140 Gadwall from Europe, Asia, and North America (including 5 populations).
		Evidence suggests that Gadwall recently colonized North America from Europe and/or Asia, but more intensive sampling is needed to confirm this pattern.
