Morvin produces gas and oil from Jurassic sandstone in the Tilje, Tofte, Ile, Garn and Spekk Formations. The reservoirs lie in a rotated and tilted fault block at a depth of 4,500-4,700 metres. They have high pressure and high temperature (HPHT). The Garn Formation is relatively homogeneous, while the Ile Formation is more heterogeneous. The Spekk Formation has good reservoir properties.
