Real-time monitoring of wellbore fluids is of crucial importance for oil recovery. During
various operations such as drilling, production, stimulation, and intervention, the …

The viscosity of subsurface hydrocarbons is commonly determined by sampling produced
fluids at the surface. However, bringing hydrocarbons to surface temperature and pressure …

A method and device are described for making in situ measurements of the density and
viscosity of downhole fluids at subterranean wells. An oscillator circuit is deployed in the well …

The ability to characterize fluids as they are being produced is of great importance for
reservoir management in the petroleum industry. Real-time information about changes in …

In this paper, a new high-pressure viscosity measurement system using a capillary method
is reported. In this system, two pressure balances are used to generate stable pressure and …

The introduction of downhole fluid analysis (DFA) two decades ago was a major addition to
the wireline formation testing suite of measurements previously available in the industry …

Measurement of oil's internal flow resistance, usually known as viscosity, is essential in
several domains such as automotive and oil production. Although different types of …

The development of the Wilcox formation in the Gulf of Mexico is constantly pushing
technical boundaries in the oil industry. Here, ultra-deepwater wells are needed to target …

The introduction of downhole fluid analysis (DFA) two decades ago was a major addition to
the wireline formation testing suite of measurements previously available in the industry …

During oil spill incidents, large amounts of oil mixtures spread through open water. Studies
have shown that the effectiveness of oil cleaning techniques depends on knowing the actual …
