摘要： Optical measurement devices including one or more sealing assemblies are described. The sealing assemblies are configured for use at relatively high temperatures and pressures, such as temperatures over 200 degrees F. and pressures over 10,000 psi. The sealing assemblies can include a deformable seal element surrounded on each side by a backup seal element. In some examples, the deformable seal element is formed of a material selected from a group consisting of a fluoroelastomer or polytetrafluoroethylene, and the backup seal elements are formed of a material selected from a group consisting of flexible graphite or metal foil. Optionally, at least one additional seal element functioning as an extrusion barrier can be placed on the opposite side of one or both backup seal elements from the deformable seal element. The additional seal element can be formed of polyether ether ketone or flexible graphite, for example. Additional devices and assemblies are described.

摘要： A downhole piston accumulator system is disclosed, such as for a formation tester. The soft piston of the system is designed to withstand high pressure downhole fluids in small volume cylinders, the fluid being collected for optical fluid identification or other analyses. The temperature range of the fluid may vary widely, which can be accommodated by the soft piston. Sealing components on the soft piston include additional materials for sealing the soft piston and otherwise helping to accommodate the wide ranging pressures and temperatures. The piston container or cylinder is designed to properly capture the piston and accommodate piston movement. The piston accumulator system allows an outer or exterior position sensor to detect piston movement, such as by a magnetic sensor.

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.

摘要： The present invention relates to a method for measuring the characteristics of a downhole fluid. The method for measuring the characteristics of a downhole fluid includes passing a downhole fluid sample through an analyzer, analyzing the downhole fluid sample by illuminating the downhole fluid sample with light from a light source and detecting light that interacts with the fluid sample. The method is applicable to detecting carbon dioxide and/or hydrogen sulfide directly in a downhole environment.

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.
