Abstract
Summary
Maui Gas field is one of the most important gas/condensate fields in the Southern Taranaki Basin (STB). Maui Gas Field includes an area of about 150 square kilometres and represents one of the largest hydrocarbon accumulations in the New Zealand peninsula with average total production rate of ∼3600 bcf of gas and 190 mmbbl oil / condensate[1–2]. Mangahewa Formation was interpreted to have porosity range (12–19%) with higher intergranular permeability (∼100–500mD) whereas Farewell Formation contained slightly higher porosity within the range of 11–20% with lower permeability ranging from ∼40–90mD. The petrophysical modeling used a modified workflow for better volumetric estimation which gave a improved recovery factor of the major reservoirs of the Maui Gas Field.
