HOUSTON, July 6 -- Tethys Oil AB, Stockholm, plans to spud its Karlebo-1 wildcat on the 533 sq km onshore License 1/02 in Denmark in late August-early September using a rig to be moved from Lithuania.

Karlebo-1 is to be drilled to 1,800-2,400 m at a site 30 km north of Copenhagen and 8 km from a gas pipeline.

The Lavo-1 well on the 1,655 sq km License 1/03 adjacent to the west and held by the same companies encountered Cretaceous, Jurassic, and Triassic sandstones with around 20% porosity.

The seismic acquisition commitment from the 1/02 license's first phase was waived in exchange for having tested a new seismic reprocessing technique, wavelet energy absorption (WEA), on an existing seismic line (OGJ, Jan. 5, 2004, p. 32). WEA identified amplitude anomalies that correspond to the structural closure of two of the prospective reservoir horizons.

Tethys Oil is interpreting results of a late 2005 surface geochemical hydrocarbon gas survey of license 1/03.

Tethys Oil operates the licenses with 70% interest. Partners are DONG E&P 20% and Odin Energi AS 10%.
