Roch SA, Buenos Aires, has started oil production from a well drilled to appraise its 2008 San Martin discovery in Tierra del Fuego and cased a second appraisal as a possible producer (OGJ Online, Aug. 15, 2008).
According to Crown Point Energy Inc., a 51.56% interest holder based in Calgary, the SM a-1002 appraisal well started producing on Aug. 15 from the Jurassic Tobifera formation.
During the first 12 days of production, rates averaged 1,646 b/d of 35° gravity oil, 3 b/d of bs&w, and 544 Mcfd of natural gas. Choke sizes were 6-16 mm.
The well, drilled to 2,107 m TD, is 0.8 km south of the discovery well, SM x-1001.
Testing is under way of the second appraisal well, SM a-1003, which reached 2,103 m TD about 0.9 km northwest of the discovery well.
The wells are on the Angostura concession operated by Roch with a 20.28% interest.
