The drill site is located on private land near Puddletown, Dorset. The well is targeting the
Cornbrash, Bridport Sands and Sherwood Sandstone horizons.
The Wytch Farm oil field comprises three separate oil reservoirs; the Bridport
and Sherwood Jurassic sandstone oil reservoirs and the Frome clay/limestone oil reservoir. The
Bridport Sands, lying 900m beneath the surface, was discovered in 1973. The Sherwood
Sandstone reservoir, situated at a depth of 1,600m, was discovered in 1978. The Frome Clay
reservoir, containing 7.5 million barrels of oil at a depth of 750m, was discovered later. Oil
production from Wytch Farm peaked at 110,000 barrels per day in 1997 compared to 6,000
barrels per day in 1984, however, production has gradually declined since then to 50,000
barrels per day in 2002 and to 13,000 barrels per day in 2019.
