Description/Abstract The Hewett gas field is 15 miles off the Norfolk coast, and has an estimated 3.5 trillion cu ft of recoverable gas contained in 2 Triassic Bunter sandstones.^ The field was discovered late in 1966 and placed on production in July 1969.^ By that time, 22 wells had been drilled, permanent offshore and onshore facilities installed, unitization negotiations concluded, and market secured.^ The contract with the purchaser calls for a gradual increase in daily production to an average rate of 600 MMcf by 1974.^ The 2 reservoirs are largely coextensive, and the field, roughly elliptical in outline, has a length of 18 miles and a maximum width of 3 miles.^ Average depth to the middle Bunter Sandstone is 3,000 ft and to the lower Bunter Sandstone is 4,150 ft.^ Maximum observed gross pay thicknesses are 323 ft (middle) and 202 ft (lower).^ Both reservoirs have excellent porosity and permeability.^ The Hewett structure is apparent on seismic profiles and at both bunter levels a fault-bounded, NW.-SE.-trending anticline is present.^ The gas in the lower Bunter differs from that in the middle bunter in that it is free of hydrogen sulfide.
