Prod probes Statoil's seabed soils

摘要

Making its European debut, Benthic Geotech's seabed drilling spread operated 1300m below the water line to obtain continuous cores down to 100m at Statoil's Luva field.rnStatoil marine geotechnics and geohazards specialist Tor Inge Tjelta says his company first started thinking about using such a unit for continuous coring and testing of downhole soils for foundation purposes a couple of years ago. Carrying out shallow geotechnical drilling programmes from surface vessels raises a number of issues, he says, notably the time required to run the pipes through the water column and exposure to weather.
