HOUSTON, Jan. 26 -- Caspian Holdings PLC reported it has started production from Jurassic pay in three wells in Kazakhstan's onshore Zhengeldy oil field.

The wells, Nos. 114, 112, and 111, are part of a seven-well drilling program. Caspian Holdings didn't disclose production rates.

Well 114, drilled to 600 m TD and completed last November, encountered 9 m of pay in two intervals: 348-354 m and 271-274 m.

Well 112, drilled to 400 m and completed in December, found 16 m of oil pay at 229-233 m and 299-311 m.

Well 111, also drilled to 400 m, found 13 m of oil pay at 211-212 m, 219-220 m, 225-233 m, and 303-306 m. It was completed this month.

An earlier well, No. 113 completed last August, was drilled to 630 m TD and encountered 13 m of oil pay at 308-302 m, 347-344 m, and 271-267 m. And Well 123, drilled last October on the flank of the structure, had high shale content and wasn't completed.

The four wells were perforated at the lower levels to generate initial production volumes. Caspian expects to increase production rates as shallower intervals are brought into production and warmer weather allows construction of new flow lines and field equipment.

Caspian Holdings plans to drill deeper Triassic sections of the reservoir. The next four wells are slated for completion by the end of March. The company's goal is to increase production to 4,300 b/d by yearend.
