Abstract: Sediments at depths of 3.5-5 km are in the "oil-generating window", the zone in which most liquid hydrocarbons are formed. Primary recovery of oil is usually only 20-30% of the total, but techniques such as injection of water or gas can usually double it. Seismic reflection is the most common method of exploration. The two major discoveries in New Zealand have been the Kapuni and Maui fields, discovered in 1959 and 1969 respectively. Both are gas and condensate fields
