    Abstract: The disclosed embodiments include downhole sample extractors and downhole sample extraction systems. In some embodiments, the downhole sample extractor includes a sample container chamber that holds a sample container containing a downhole sample. The downhole sample extractor also includes a sample extraction chamber having an internal chamber that is partially filled with a carrier solution, wherein the downhole sample is mixed with the carrier solution in the internal chamber of the extraction container. The downhole sample extractor further includes a first piston that, when actuated, inserts the sample container into the internal chamber of the sample extraction chamber.

    Abstract: A downhole formation fluid viscometer sensor and method therefor include a viscometer sensing package, a flexible diaphragm, a magnet and electric coil, and a signal pickup assembly. The viscometer sensor may also include a first cavity and a second cavity for mechanical and electric energy transfer. The magnet and electric coil may be driven by external alternating current to generate an electromagnetic force. Silicon oil may be used to fill the first cavity and/or a pressure balance hole may connect the first cavity to an external area. The diaphragm may be a titanium alloy and a ferromagnetic magnet may be attached to the diaphragm. The diaphragm preferably has a thickness from about 0.030 to about 0.040 inches and the magnet and electric coil can propel the diaphragm to vibrate at a frequency from 0 to 100 kHz. Formation fluid viscosity is determined using resonant frequency linewidth, with contributions from the sensor package intrinsic properties removed.

    Abstract: Technologies for propagating optical information through an optical waveguide in a downhole environment are provided. An example method can include generating a light signal via a light-emitting device at a first location on a wellbore environment; propagating the light signal through an optical waveguide on an inner surface of a wellbore tool, the optical waveguide including a first layer of low refractive-index material, a second layer of high refractive-index material applied to a first surface of the first layer, and a third layer of low refractive-index material applied to a second surface of the second layer; and receiving, by a detector at a second location on the wellbore environment, the light signal via the optical waveguide on the inner surface of the wellbore tool.
