Caspian Oil & Gas Limited is pleased to provide an update from its West Mailisu #2 well on the Company’s 100 percent-owned West Mailisu licence in the Kyrgyz Republic, Central Asia.

Caspian reported on 12 September that its West Mailisu #2 well was suspended awaiting production testing with a progressive cavity pump (PCP).

The PCP proved incapable of lifting the fluid to the surface, although on pulling the completion from the hole oil was found within 8m of the surface. As the pump had been set just above the perforations (around 1680m) it is possible to conclude that there is little to no water being produced from the formation. Currently, there is around 75bbls of fluid in the hole which is most likely entirely oil. In order to test and produce from the well, we are currently determining the appropriate pump and will commence production testing once the equipment has been sourced.

Once having undertaken the production test in-well-bore radial drilling or fraccing will be considered as a way to enhance productivity. Initial estimates suggest that there is a potential mean recoverable resource of 1.0 million barrels, with an upside case of 2.2 million barrels of oil within Bed III of the West Mailisu structure. The West Mailisu prospect lies adjacent to the Mailisu IV oil field, which has produced more than 42mmbbls of oil.

Caspian Oil & Gas Limited (ASX: CIG) reports that its rig was drilling ahead on its West Mailisu #2 well at 1,568m at 8.00 am Perth time, on the way to a casing point at 1,700m and the primary target (sandstone Bed III) at 1,740m. The limestone Beds V and VII will then be tested prior to reaching the proposed well depth of approximately 2,000m.

The West Mailisu #2 well is on Caspian’s 100% owned West Mailisu licence in the Kyrgyz Republic, Central Asia.

The West Mailisu prospect lies adjacent to the Mailisu IV oil field, which has produced more than 42mmbbls of oil. West Mailisu #2 will target oil in Eocene age sands and carbonates (Beds III, V & VII).

The targeted feature is defined by a NW-SE trending reverse fault on the northern flank. Seismic sections across the structure indicate a robust closure.

The prospect has the potential to contain oil reserves of up to 9.7mmbbls, with mean potential reserves of 4.5mmbls calculated for the Eocene reservoirs.

The well is being drilled by Caspian’s own rig to a depth of approximately 2,000m, testing the Eocene and upper Cretaceous sands.
