Abstract: One example of determining well fluid flow velocity based on vortex frequency is implemented using a well fluid flow velocity measurement system. The system includes a well fluid flow monitoring unit to determine a parameter of a well fluid flow in response to a vortex being produced in a well fluid, and provide the parameter. The system also includes a controller to receive the parameter determined by the flow monitoring unit, determine a frequency of the vortex from the received parameter, and determine a flow velocity of the well fluid based on the determined frequency.

Abstract: The present disclosure relates to methods for determining the compressibility of downhole fluids using measurements obtained during over-pressurization of a formation fluid sample. In certain embodiments, the density of the fluid may be measured as the fluid is directed through a flowline into a sample chamber. The density measurements can be employed in conjunction with pressure spikes that occur during over pressuring of a sample chamber to determine the compressibility.
