Caspian Oil and GAs has issued its July 2011 Quarterly reports covering its operations in the Kyrgyz Republic and the West Mailisu wells.

Kyrgyz Republic

 West Mailisu #2 well on Caspian’s 100%-owned West Mailisu licence spudded on 13 June
 Well is adjacent to the Mailisu IV oil and gas field, which has produced 42mmbbls oil to date
 Good shows in Bed II over the interval 1691-1697m
 Intermediate casing point set at 1713m with first primary target sandstone Bed III (1740m) expected to be penetrated in late July
 Charvak Block seismic reprocessed – a total of 241km has been undertaken to date Romania
 Awaiting ministerial signature on Parta Licence Agreement – expected in 4th quarter 2011

September quarter plans

 A follow-up well to West Mailisu #2 will be considered if the results justify it
 Planning for the acquisition of up to 120km of 2D seismic in Kyrgyz licences
 Ongoing search for additional central Asian opportunities

Background

Caspian Oil and Gas, through its subsidiaries, holds a number of licences in the Fergana Basin, giving it a significant exploration position in the Kyrgyz Republic in Central Asia.

West Mailisu #2

In June, the Company spudded the West Mailisu #2 well on its 100%-owned West Mailisu licence, which is adjacent to the Mailisu IV oil and gas field. Mailisu IV has produced 42mmbbls of oil to date. The well-site is located at the interpreted structural crest of a four-way dip-closure (see Figure 2).
The Company believes West Mailisu #2 has the potential for oil in Eocene-age sands and carbonates (beds III, V and VII) and gas in the Cretaceous and Jurassic-age sands. Prospective oil resources of up to 9.7mmbbls (mean 4.5mmbbls) had been calculated for the Eocene reservoirs.

Prospective gas resources of 5-10bcf are mapped in the Cretaceous or Jurassic reservoirs, although West Mailisu #2 was planned to test only the upper Cretaceous sands, due to depth limitations of the rig. 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 (see figures 3 and 4). Caspian plans to target oil and gas potential in
the deeper Cretaceous and Jurassic age sands in a follow-up well, should West Mailisu #2 be successful.

West Mailisu #2 spudded on 13 June 2011, using Caspian’s own rig. Surface casing was set at 20m, 9 5/8-inch casing was set at 350m and intermediate 7 inch casing set at 1713m.

By late July the rig was drilling through the primary targets, Beds III, V and VII, on its way to the target depth of 2000m. Good oil shows were recorded over a six metre interval in Bed II (1691-1697m). The commerciality of this unexpected discovery has not been assessed, but the presence of oil in Bed II increases the likelihood of closures occurring in Beds III, V and VII.
