HOUSTON, June 4 -- Swift Energy Co., Houston, has tested one exploration well and is continuing work on four others in South Texas, company officials said Monday.
The Vaughn No. 1 well in the company's Rome Prospect in Willacy County tested at an initial rate of 12.5 MMcfd of gas and 160 b/d of condensate on a 17/64-in. choke with a flowing tubing pressure of 8,900 psi. Swift Energy is operator, with 65% working interest.
That discovery should be producing by the end of June, following construction of a gas-gathering line, said Swift Energy officials.
Meanwhile, they said the Kinnally No. 1 wildcat was drilling below 10,900 ft, targeting the Wilcox sands in the Falcon Ridge Prospect in Zapata County. The Mallet No. 1 was at 12,600 ft, targeting deeper Frio sands in the Sienna Prospect in Willacy County. Swift Energy is operator for both of those wells, with working interests of 25% and 65%, respectively.
Workers are setting a liner at 15,800 ft in the Foster Minerals No. 1 well on the Lion Prospect in San Jacinto County. They will drill another 300-500 ft before initiating additional testing, officials said. Swift Energy is operator with 49% working interest.
The Post No. 1 well in the Nita No. 1 Prospect in Goliad County has been drilled to 14,937 ft TD, with Swift Energy as operator with 76% working interest. Production casing was set and final completion in potential Wilcox sands is awaiting construction of a tank battery, said officials.
Moreover, Swift Energy participated in drilling seven development wells in the first half of this year, including six as operator. Those have been placed in production, boosting Swift Energy's average US production to more than 140 MMcfd of natural gas equivalent, officials said.
In New Zealand, Swift Energy is still drilling its Kauri-A1 well at 8,679 ft Plans call for workers to set a 9 5/8-in. casing to a depth of 9,840 ft and to drill an 8.5-in. hole to 14,760 ft to evaluate potential Tariki sand, Rimu lime, and Cretaceous sands on that large structure.
The Kauri structure is immediately south of the Rimu structure, where previous wells have encountered upper and lower sections of both the Tariki sand and the Rimu lime.
