"The Maari Field is a large oil field located in the southern part of the Taranaki Basin, New Zealand. The field is bounded by two major structures, the Eastern Mobile Belt and Western Stable Platform. The Maari Field produces 40,000 BOPD (Barrels of Oil per Day) from five wells from reservoirs in the Moki Formation. The Miocene Moki Formation was deposited as part of the Wai-iti Group and consists of sandstone interbedded with siltstone and claystone. The sandstone of the Moki Formation is characterized by a submarine fan. It is distributed along the southern and central Taranaki shelf. Three-dimensional seismic data and well logs were recorded by the Geco-Prakla Company. Time and depth structural maps on the top of the Moki Formation are subdivided into a main structure with high and low elevations of topography, which are separated by a major fault, the Kiwi Fault. The fault trends from the south toward the northeast. Seismic attributes, such as coherence and edge detection, were mapped to interpret the major and minor faults. In the Maari Field, there are more than seventeen faults. Seismic data and well log data were used to determine the petrophysical properties in the Moki reservoir. Using the well logs, the transition zone (oil-water contact) between the oil and water was found to be 1352 m. The Moki reservoir has good quality oil, with an average porosity at Maari-1, Maui-4, Kea-1, Moki, and Maari-2 ranging from 14 to 19 percent. Gamma ray, resistivity, and spontaneous potential logs were used to determine correlation between well and lithology of the Moki reservoir. The net thickness of the reservoir is 320 m to 360 m. The distribution of shale is less than 10 percent throughout the Moki reservoir"--Abstract, page iii.
