"The Company expects to spud Heron 1 in early July.
The well will be drilled to a planned TD of 3,050 metres and will take approximately 40 days to drill and log. The Heron Prospect is the southerly extension of the proven oil-bearing structure drilled by the T19-46-3 discovery well in adjacent Block XIX. The latest mapping based on reprocessed 2D and newly accessed 3D seismic shows the majority of the structure, including the crest of the trap, lying in Block XX. The Heron Prospect is estimated to have mean recoverable prospective resource potential of 25 MMbo. Heron 1 will be located 1.1 km south of the T19-46-3 oil well and is prognosed to encounter the top of the primary reservoir targets at approximately 2,800 metres.
On completion of operations at Heron 1, the rig will immediately move to the Gazelle 1 location.
The planned TD of Gazelle 1 is 2,500 metres and the well is expected to take approximately 35 days to drill and log. The Gazelle Prospect is located on the south-western flank of the Tamsag Basin, which is the primary source kitchen charging the Block XIX discoveries. The Gazelle 1 well will be drilled 5 km west of Heron 1 and 4.5 km southwest of the T19-46-1 oil well in Block XIX. The mean prospective recoverable resource assessment for the Gazelle Prospect is 13 MMbo.
The Red Deer 1 well will be drilled with the Daton rig and is expected to spud later in July and is forecast to take 35 days to drill and log. The planned TD of the well is 2,100 metres. The Red Deer 1 well will target a basin centre, fault bounded, structural closure in the southern part of Block XX. The mean prospective recoverable resource assessment for the Red Deer Prospect is 48 MMbo. On completion of drilling and depending on the success of the well, the Company will then take the decision to whether to drill a further well at Red Deer, move the rig to drill a well in Block V, or focus on activities in the north of Block XX.
Running two rigs, with a separate workover rig for any testing operations, should give the Company sufficient time to complete its 2019 drilling campaign before the winter operational shutdown in late Q4 2019."
