Abstract

See full text

A downhole viscosity sensor and related systems and methods are disclosed. The sensor includes a first fluid flow path including a turbine and a velocity sensor, a second fluid flow path including a second turbine and a second velocity sensor, a mechanical or electrical linkage linking the first turbine and second turbine to cause the turbines to rotate in unison. The sensor also includes a field generator, which may be a magnetic field or electric field generator. The first fluid flow path includes an open flow path for receiving a fluid from a formation and the second fluid flow path includes a closed flow path having a reference fluid that has a variable but known viscosity.
