The Miller field lies in blocks 16/7b and 16/8b of the UKCS and was discovered in 1982. The Miller reservoir is an Upper Jurassic submarine-fan sandstone with a typical true vertical depth of 13,200 feet (4000m). The field currently produces circa 125mbpd from seven wells. The oil contains 11% by weight of carbon dioxide and the gas typically contains 200 ppm (vol/vol) of hydrogen sulphide. General reservoir fluid parameters are listed in Table 1.
