Seven offshore wells were completed off New Zealand in 1970. Shell's Maui No. 3, on test in Feb., produced at the rate of an aggregate potential 87.5 million cu ft of gas a day and 4,000 bbl of condensate from 2 zones. Maui had been discovered early in 1969. Three earlier wells produced gas and condensate with Maui No. 1 having some oil as well. The field is now said to be among the 15 biggest gas fields in the world, with reserves of at least 6 trillion cu ft indicated. All 4 Maui wells were in more than 300 ft of water, Maui No. 1, the deepest, at 363 ft. Estimates for costs of developing the field range up to $300 million. Crude oil reserves at Maui do not justify development on their own, and at this stage the future of the field remains a subject for speculation. Its prospects lie in natural gas and condensate production, but the present New Zealand gas market is already supplied by Kapuni gas field onshore. In the New Zealand concessions closer to shore and over the continental shelf proper, it is expected that drilling will resume soon to test all possibilities. Water depth, distance from shore and bad weather conditions in most of the prospective areas will require technological skills beyond those presently available for commercial operations.
