摘要： Various methods and tools optically analyze downhole fluid properties in situ. Some disclosed downhole optical radiometry tools include a tool body having a sample cell for fluid flow. A light beam passes through the sample cell and a spectral operation unit (SOU) such as a prism, filter, interferometer, or multivariate optical element (MOE). The resulting light provides a signal indicative of one or more properties of the fluid. A sensor configuration using electrically balanced thermopiles offers a high sensitivity over a wide temperature range. Further sensitivity is achieved by modulating the light beam and/or by providing a reference light beam that does not interact with the fluid flow. To provide a wide spectral range, some embodiments include multiple filaments in the light source, each filament having a different emission spectrum. Moreover, some embodiments include a second light source, sample cell, SOU, and detector to provide increased range, flexibility, and reliability.

摘要： A processor accepts sensor data about a geological formation from a sensor. The sensor data is such that processing the sensor data using a processing technique to estimate a parameter of the geological formation without a constraint, whose value is not yet known, produces a plurality of non-unique estimates of the parameter. The processor accepts more than two time-displaced images of fluid sampled from the geological formation. The time displacements between the images are substantially defined by a mathematical series. The processor processes the images to determine the constraint. The processor processes the sensor data using the processing technique constrained by the constraint to estimate the parameter of the geological formation. The processor uses the estimated parameter to affect the drilling of a well through the geological formation.

摘要： Light sources are provided with enhanced low-frequency (e.g., near infrared) emission. Some disclosed embodiments include a filament and at least one re-radiator element. The filament heats the re-radiator element to a steady-state temperature that is at least one quarter of the filament's absolute temperature. As disclosed herein, the increased surface area provided by the re-radiator element provides enhanced IR radiation from the light source. Patterning or texturing of the surface can further increase the re-radiator element's surface area. Various shapes such as disks, collars, tubes are illustrated and can be combined to customize the spectral emission profile of the light source. Some specific embodiments employ a coating on the bulb as the re-radiator element. The coating can be positioned to occlude light from the filament or to augment light from the filament, depending on the particular application. The various re-radiator elements can be positioned inside or outside the bulb.

摘要： Apparatus, systems, and methods may operate to receive incident energy within a chamber defining a first part of an interaction volume that attenuates the incident energy as a function of path length to provide attenuated energy. Additional activity may include simultaneously transforming the attenuated energy characterized by a substantially exponential intensity function into resultant energy characterized by a substantially polynomial intensity function. The transformation may be accomplished using an interacted energy transformation element that defines a second part of the interaction volume, the transformation element operating to intercept the attenuated energy along a plurality of path lengths. Other activity may include transmitting the resultant energy to a receiver. Additional apparatus, systems, and methods are disclosed.

摘要： Downhole spectrometer tools are provided with two ways to increase the number of filters on an optical path. A first approach employs multiple filter wheels that rotate alternately in a common plane to intersect the optical path. Portions of the wheels are cut out to avoid mechanical interference between the wheels. A second approach drives the one or more filter wheels with a wobble that causes the filters to trace one or more hypocycloidal curves that each intersect the optical path.
