Onshore
wells
Onshore wells are numerous in Latvia, but the majority of these wells were drilled before 1970, with well
sites chosen based on limited quality seismic. The wells all had targets
in Lower Palaeozoic prospects, but based on current knowledge many of
these exploration wells were drilled off-structure.
They
are of many different kinds and status, from exploration wells with
discoveries, shows and dry holes, to wells drilled for hydrogeological
or stratigraphical purposes.
Note: The
well co-ordinates are given based on the archive data; they could differ
from those measured in situ using GPS by 5-100 m, and even more some
wells.
