Apache, Chevron to partner on Kitimat LNG project
Apache Canada has completed a transaction with Chevron Canada to build and operate the Kitimat LNG project and develop natural gas resources at the Liard and Horn River basins in British Columbia, Canada.
Each company is 50% owner of the Kitimat LNG plant, the Pacific Trail Pipelines and 644,000 gross undeveloped acres in the Horn River and Liard basins. After a brief transition period, Chevron Canada will assume operatorship of the LNG plant and the pipeline. Apache Canada increased its ownership in the LNG plant and pipeline from 40% and will operate the upstream assets. Apache’s net proceeds from the transaction were $405 million.
Liard and Horn River are two of the most prolific shale gas plays in North America, with more than 50 Tcf of resource potential on the Apache-Chevron acreage.
Eni makes oil discovery in Western Desert of Egypt
Eni recently made a new oil discovery from the NFW well, Rosa North 1X, located in the Meleiha Concession in the Western Desert of Egypt. The well encountered a total oil pay of approximately 80 meters in multiple good-quality sandstones of the Bahariya, Alam El Bueib, Khatatba and Ras Qattara reservoirs and has been successfully tested in the reservoirs flowing a 43° to 48° API oil at very good rates.
The discovery will likely lead to the drilling of at least two development wells in 2013. Production for each well is estimated at 2,000 bbls of oil/day.
Separately, Eni and Sonatrach have started gas production from the Menzel Ledjmet East field in Block 405b, approximately 1,000 km from Algiers. A plant, located in the field, allows for the treatment of rich gas for the daily production and sale of 9 million cu meters of gas, 15,000 bbls of oil and condensate, and 12,000 bbls of liquefied petroleum gas.
Chevron finds gas again in Australia’s prolific Carnarvon Basin
Chevron’s Australian subsidiary has made the 20th discovery off the Western Australian coast since mid-2009 following further drilling success in the Exmouth Plateau area, located in the prolific Carnarvon Basin.
The Kentish Knock South-1 exploration discovery well encountered approximately 246 ft (75 meters) of net gas pay in the upper Mungaroo Sands. The well is located in the WA-365-P permit area approximately 173 miles (280 km) north of Exmouth off the Western Australian coast.
The well was drilled in 3,832 ft (1,168 meters) of water to a total depth of 10,056 ft (3,065 meters).
“The Asia Pacific region is key to Chevron’s growth strategy, and our strong Australia natural gas portfolio continues to be bolstered by our strategic approach to finding and developing resources that will help meet the growing energy needs in the region,” said George Kirkland, Chevron vice chairman.
Chevron Australia is the operator of WA-365-P with 50% interest while Shell Development (Australia) holds the other 50%.
