Oman, Block 15, Jebel Aswad
Block 15 is situated in the north western part of central Oman and covers a area of about 1,400 square kilometres.
Two wells have been drilled since Tethys entered the licence. The Jebel Aswad-1 ("JAS-1") well was drilled in 2007. Upon testing, it flowed 11.03 mmcfpd of gas and 793 bopd of condensate (total of 2,626 boepd). The JAS -2 well, drilled in 2008, showed the same log response whilst drilling as the JAS-1, however, the JAS -2 well tested however only water. In 2008, a 3D seismic survey covering 285 square kilometres of the Jebel Aswad structure was conducted.
Work program
The main efforts on Block 15 is focused on finding the most economic method of putting the JAS-1 well in production. An extension of the 3D seismic survey shot in 2008 is also planned before drilling activities will resume.
