Apache added to its natural gas portfolio with two discoveries in the Gulf of Mexico. The West Cameron 615 A-4 well tested at 35 MMcf/d of gas and encountered 180 ft of pay in two zones. The second well, High Island 86 No. 1, flowed 17.5 MMcf/d of gas from a dual completion. The two wells tested at a combined rate of 52.3 MMcf/d of gas and are now on production.
Husky Oil's appraisal well L-08 on the White Rose Field in the Jeanne d'Arc basin off Newfoundland encountered oil. The well drilled a oil reservoir with a producing zone more than 330 ft-thick and flowed a combined 5,000 b/d of oil from two tests using a restricted choke. The well is located about 30 miles east of the Hibernia Field. Another appraisal well will be drilled about 2 miles south of the well in the fourth quarter of this year.
Tana Oil & Gas has made a gas discovery on Ship Shoal Block 278 in the Gulf of Mexico in 200 ft of water. The well opened approximately 20 net ft of pay in two intervals. The company will contract to build a production platform for the discovery next year. The well is the second of a 12-prospect exploratory program begun in May.

Conoco encountered extensive natural gas zones with two wells drilled offshore Indonesia in Block B of the West Natuna Sea. The well West Belut #2 and Belut #5 were drilled to delineate the gas zones of the three-field Belut complex encountered by the Belut #3 well. Conoco said that two wells drilled into the Arang and Udang formations have the potential for high production rates of gas with minimal carbon dioxide. Conoco holds 40% in the West Belut and South Belut fields with partners Indonesia Petroleum (35%) and Texaco (25%).
The first well drilled with the new Deepwater Frontier deepwater drillship is unsuccessful. The well was drilled offshore New Zealand by operator Conoco, co-owner of the drillship, in 4,812 ft of water about 90 miles northwest of Auckland. The well did not encounter any hydrocarbons. Conoco holds a 57% interest in the block, which covers over 12 million acres.
Mitsui Oil Exploration has pledged to spend $35 million on oil exploration in Thailand this year. The announcement came following an agreement the company reached with the government of Thailand for the acquisition of a 4% stake from PTT Exploration and Production in blocks 14A, 15A, and 16A in the Gulf of Thailand.
Unocal has again confirmed the commerciality of the Pakarang gas field in the Gulf of Thailand with four new delineation wells. The Pakarang 6, 7, 8, and 9 wells each encountered 161-347 ft of natural gas-bearing sands. Unocal now estimates the gross gas resource potential to be between 275 and 550 Bcf. Pakarang lies in concession Block 11 and was originally discovered in 1983. The company is currently reviewing the data to determine the field development plan.
