Texon

Wireline logs from Texon's Tallebudgera-1 well, onshore Gulf Coast South Texas, has indicated two potential gas-bearing formations with a combined thickness of 6.1m, the company said.

The upper sand is at 892m and has a thickness of 4.9m, while the lower sand lies at 1038m with a thickness of 1.2m.

Texon said production casing would be run in preparation for testing the lower zone in the next 10 days.

If this test is successful, the well will be placed on production from this zone. If not, the company plans to test the upper zone, Texon added.

Following production casing, Texon will drill Fingal-1 well, the seventh well in its 2008 shallow program.

According to the company, the Fingal prospect has an estimated gross gas resource potential of 0.3-0.4 billion cubic feet.

Texon has a 95% working interest and a 66.50% net revenue interest in Tallebudgera-1, and a 95% working interest and a 71.25% net revenue interest in Fingal-1.

Golden Gate

Also in Texas, Golden Gate's two Manzano shallow wells in the Manzano Shallow project on Padre Island are flowing at a combined rate of 2.5 million cubic feet per day.

The company said the first Manzano well ST 991-1 recommenced production, producing at an initial rate of 1MMcfd of gas from two 4ft intervals perforated in the Marg Frio formation.

ST 991-1 originally tested a deeper Marg Tex interval, but further examination of the interval determined that it would not be productive beyond its initial short production, Golden Gate said.

The second Manzano Well, Dunn McCampbell-11A, has been brought into commercial production after flowing gas on test operations.

The well has been tied directly into the sales grid along with Golden Gate's other producing wells, and has been producing at a rate of 1.5MMcfd of gas from a perforated 8ft interval over an extended production testing period, the company said.

Golden Gate has a 35% interest in the two wells.

Antares

Meanwhile data gathered from Antares' Stewart-1 well in Wharton County, Texas has indicated potentially attractive sands for the prospect could have been missed by at least several hundred feet.

Antares said the well reached a total depth of 11,992 feet on June 7 and the targeted turbidite channel sand was not well developed at this location.

The company will now test the overlying Jackson sand encountered while drilling the last section.

If the Jackson sand successfully produces hydrocarbons it will be put into production, Antares said.

The company and its joint venture partners are also evaluating the potential for a sidetrack at a later date.

Antares has a 26.25 working interest in Stewart-1.
