West Mailisu well spudded
Posted: 24 July 2008
Caspian's 100 per cent owned West Mailisu Well #1 spudded 1300hrs on 21 July, and was this morning drilling ahead at 170m, heading towards a total depth of 1,000m.
The well is designed to test the presence of oil on the western flank of the Mailisu III structure, some 3km west of earlier drilling.
While considered to be a higher risk well, if successful, the presence of oil will significantly expand the resource potential of the Mailisu III field.
This well will complete the initial six well appraisal programme for the Mailisu III oil field before the rig is upgraded with the view to drilling deeper prospects in the southern Fergana Basin.
All five wells drilled to date have encountered oil in the Palaeogene limestone Beds V and VII, but flow rates are likely to be modest at up to 10 barrels of oil per day due in part to low formation pressure at the shallow depths (620m-650m).
The same target reservoirs are being tested at West Mailisu Well #1 at a depth of approximately 950m. At greater depths higher flow rates could be expected.
