Abstract

The rig and ancillary gear were shipped by the 300-ton landing barge "Wewak" from Kaufana, Papua, to Wilson Island, a distance of approximately 1,000 miles. They were thence transferred to Wreck Island by the drilling company's landing barge "Tamona" of 47.38 registered tonnage. All stores, supplies, and fresh water were transported 58 miles from Gladstone by the "Tamona". Communications were maintained by an A.W.A. 5A Transceiver with OTC Station VIR Rockhampton. The bore was spudded in at 1400 hours, 7th May, 1959. 12-1/4 inch hole was drilled to 493 feet. Owing to lost circulation, no cuttings could be recovered from the hole, and a laborious system of bailing was resorted to. The 12-1/4 inch pilot hole was opened to 17-1/2 inches, and 13-3/8 inch J55x54.5 lb. STC casing was run to 480 feet. 12-1/4 inch hole was drilled to 1,170 feet, but owing to porous unconsolidated sediments and lost circulation in higher zones it was decided to run and cement 9-5/8 inch J55x40 lb. STC casing at 1,110 feet. 8-1/2 inch hole was then drilled to total depth, 1,898 feet. Recent, Pleistocene, Pliocene, and Miocene sediments were penetrated; basement was encountered at 1,795 feet. Fourteen cores were cut during the drilling of the bore, using a 20-foot Reed K500 "Kor-King" barrel. Both hard and soft formation 5-5/8 inch core heads were used. The hole was logged to total depth with a Failing Logmaster, giving the self-potential, 16 and 63 inch normal and single point resistivity, and gamma ray curves. No shows of oil or gas were noted, and in consequence no drill stem tests were carried out. Three deviation surveys were made; the maximum deviation was 1/2 degree at 1,580 feet. The bore was abandoned as a dry hole by placing cement plugs from 1,160 to 1,060 feet and from 50 feet to surface; a metal name plate affixed to a projecting pipe was welded on to the cap sealing the bore.
