PETROLEUM OIL Activity in the petroleum mining industry was again confined to the operations of New Zealand Oil Refineries, Ltd., which, in addition to maintaining production from the old wells in the Moturoa field near New Plymouth, completed a new well, the Dobson No. 1. Although this well was not completed until March, 1949, production from it alone amounted to 180,970 gallons of crude oil as compared with 55,493 gallons from the three old wells. This result has encouraged the company to commence a new well, the Dobson No. 2, and despite some misfortune at the commencement of operations, satisfactory progress has been made in sinking the bore hole. Production from the Moturoa field for the year 1949 amounted to 236,463 gallons, as against 83,112 gallons in 1948, 82,307 gallons in 1947, and 81,625 gallons in 1946. The total production of crude petroleum in New Zealand up to 31st December, 1949, now amounts to 3,986,316 gallons. COAL-MINING The total coal-production of the Dominion for the year 1949 amounted to 2,813,275 tons, which is 37,389 tons greater than production in 1948, which amounted to 2,775,886 tons.
