Increasing demand means oil companies with major offshore businesses are drilling new wells to depths of 25,000 to 35,000, which are under pressures ranging from 25,000 to 30,000 psi. A new high-pressure viscometer for oil, gas and supercritical fluids, the Cambridge Viscosity Viscolab PVT option can now extend its pressure range from 20,000 psi to 30,000 psi while maintaining its user-friendly operation and minimal sample usage of only 6 ml.
