block 105 rig all go, page-2

looking at the ensco update mid april

ENSCO 107 KFELS MOD V-B 400 -----Mitra Energy Low 160s Vietnam Aug. 14 -----. -----. Plus two 1-well options. Then to OMV in New Zealand Oct. 13 to Aug. 14, low 230s. Plus cost
adjustments and one 90-day unpriced option. Mob fee to be amortized over primary contract term

so at that stage ENI's name was blanked out. According to the 4th May Mitra announcement

Exploration well 46/07-ND-1X was spudded today in Block 46/07, offshore Vietnam, by the partnership of the Block 46/07 PSC. The well is the first of the 3-well drilling campaign operated by subsidiaries of Mitra in Vietnam in 2013. The drilling operations are being carried out by the jack-up drilling rig "Ensco 107".

so have we bought one of the options of Mitra is that how it works?
