Abstract
Embodiments of the present invention are directed to an apparatus for acquiring physical properties of a fluid sample at high temperatures and pressures. The apparatus comprises a sample manifold, one or more pressure intensifiers to push or pull a sample through the sample manifold, and a viscosity coil to receive a part of the sample to measure a viscosity of the sample.
Claims15
An apparatus comprising:
- a sample manifold;
- a first pressure intensifier and a second pressure intensifier coupled to opposite ends of the sample manifold, wherein the first pressure intensifier and the second pressure intensifier are configured to move to push or pull a sample through the sample manifold to cause the sample to be approximately homogenous;
- and
- a viscosity coil coupled in a bypass relative to flow between the first pressure intensifier and the second pressure intensifier in the sample manifold, wherein the viscosity coil is configured to receive a part of the sample to measure a viscosity of the sample after a viscosity coil bypass valve is in a closed position, wherein the sample is to flow independent of the viscosity coil after the viscosity coil bypass valve is in an open position.
