An apparatus for estimating a viscosity or density of a fluid downhole includes a carrier configured to be conveyed through a borehole penetrating the earth. A pump is disposed at the carrier and configured to pump the fluid. A flow restriction element is configured to receive a flow of the fluid pumped by the pump and to reduce pressure of the fluid flowing through the flow restriction element. A sensor is configured to measure a differential pressure across the flow restriction element and to provide an output that is used to estimate the viscosity or density.

Viscosity measurement in a fluid analyzer sampling tool

The disclosure provides a system, tools and methods for estimating a property or characteristic of a fluid downhole. In one aspect, the method may include: heating the fluid at a selected or first location during a first time phase, taking temperature measurements of the fluid substantially at the selected location during a second time phase, and estimating the property of the downhole fluid using temperature measurements. Temperature measurements may also be taken at a location spaced apart from the first location and used to estimate the property of the fluid. The tool may include a device that heats the fluid during a first time phase and takes temperature measurements of the fluid during a second time phase. A processor uses the temperature measurements and a model to estimate a property of interest of the fluid.

Apparatus and methods for estimating a characteristic of a fluid downhole using thermal properties of the fluid

An apparatus for evaluating downhole fluids is disclosed. The apparatus includes: an optical block having an adjustable opening that receives electromagnetic energy emitted by an electromagnetic energy source; a controller operatively associated with the optical block for adjusting the opening size, wherein the opening size is adjusted at least in part based on one or more estimated downhole parameters; and a sensor that receives the electromagnetic energy emitted by the electromagnetic energy source after the emitted electromagnetic energy interacts with a downhole fluid. A method for evaluating downhole fluids is also disclosed.

Apparatus and method for evaluating downhole fluids

A method for measuring optical properties of a fluid downhole, the method comprising measuring intensity of light interacting with the fluid downhole for each of one or more wavelengths; integrating each intensity of light for each wavelength for an integration time; and estimating the optical property from a difference between a starting value and an ending value for the integral of the intensity of light over time divided by the integration time for the wavelength. An apparatus is disclosed for measuring an optical property of a fluid downhole, the apparatus comprising one or more photodiodes that measure an intensity of light interacting with the fluid downhole for each of one or more wavelengths; and one or more integration circuits that each integrates an intensity of light for one wavelength for an integration time.
