WELL ADZE-4

The Adze-4 (or Adze PN-4) exploration well was drilled in 1989 in the dome part of the Kuldiga structure with the purpose of studying the oil prospects in the L. Ordovician and testing of the M. Cambrian oil-bearing horizon.

 

An oil flow was obtained during the testing of the M. Cambrian sandstone – 2.5 m3/day. A small oil flow was obtained from the siltstone in the Volkhov horizon (L. Ordovician).

 

The Adze PN-4 well reached the depth of 997 m in the top M. Cambrian.
