Document Type and Number:

WIPO Patent Application WO/2012/174046

Kind Code:

A3

Abstract:

Apparatus and methods for determining downhole fluid parameters are disclosed herein. An example method includes disposing a downhole tool in a well. The downhole tool has a sensor including a heater and a temperature sensor. The example method further includes flowing a fluid in the well. The example method also includes determining a first velocity of the fluid at a first depth via the sensor and, based on the first velocity of the fluid, a first parameter of the well at the first depth is determined.
