Gas Fields

AbstractSean North and Sean South are two small prolific gas fields located on the Indefatigable Shelf in the Southern North Sea. They, like most of the other fields in the area, have a Carboniferous source, a Rotliegend aeolian sandstone reservoir and a Zechstein evaporite cap rock. They have been developed to fullfil a peak-shaving role, being produced for only a few days per year in times of high gas demand when they produce at a rate of 600 MMSCFD. Initially thought to be two equally sized accumulations, there is now some evidence from material balance calculations that the Sean South is bigger than North Sean. The contractual recoverable reserves for the two fields are 425 BCF.

AbstractSean North, Sean South and Sean East are small prolific gas fields located on the Indefatigable Shelf in the Southern North Sea. They, like most of the other fields in the area, have a Carboniferous source, a Rotliegend aeolian sandstone reservoir and a Zechstein evaporite cap rock. Sean North and South have been developed to fulfil a peak-shaving role, being produced for only a few days per year in times of high gas demand when they can produce at rates of up to 600 MMSCF/D. East Sean is sold to the direct market. Reserves for the fields are 234 BCF (North), 488 BCF (South) and 127 BCF (East).

Gas Fields

AbstractThe Mercury and Neptune Gas Fields, discovered in 1983 and 1985 respectively, are located on the NW margin of the southern North Sea. Both fields have reservoirs in the Permian Lower Leman Sandstone Formation of the Rotliegend Group. The Mercury Field, at Rotliegend level, is an elongate, southerly tilting horst block. It trends NW-SE and is bounded by reverse faults. The Neptune Field, at top reservoir level is a faulted, four-way dip closed structure that is elongated in a NW-SE direction. The combined gas-in-place for the two fields is estimated at 465 BCF with recoverable reserves of 368 BCF. Development drilling on Mercury commenced in early 1999 and on Neptune it is scheduled to start in Q3 1999. The maximum gas export rate will be 250 MMSCFD with first gas anticipated in November 1999.

AbstractThe Camelot Gas Fields (Camelot North, Northeast and Central-South) lie in Blocks 53/la and 53/2 in the Southern North Sea, some 30 miles (48 km) east of Great Yarmouth. Initial sub commercial discovery wells were drilled in 1967, 1969 and 1972. Further exploration and appraisal drilling was carried out in 1987 and 1988. This paper covers the Field history up to the 53/la-10 appraisal well in June 1988. The Lower Permian, Leman Sandstone Formation is the reservoir, with the gas accumulations trapped in tilted fault terraces. The Leman Sandstone Fm. in the Camelot area is 800 ft thick with a gas column up to 200 ft. Development of the fields will be in two phases. Phase I will consist of 5 wells deviated from the Camelot 'CA' platform to produce reserves from the Camelot North and Central-South Fields. Production commenced in October 1989. Phase II scheduled for 1991/92 will tie-in the Camelot Northeast Field. Gas is exported from the unmanned 'CA' gathering platform via pipeline to Amoco's Leman 'A' complex, from where the gas is transported to shore via the existing Amoco pipeline from Leman to Bacton. Total recoverable reserves for the Camelot Fields are estimated at 215 BCF.
