Abstract: An apparatus attaches to a microscope slide to form an enclosed fluidic chamber with input and output ports, where a tissue or cell sample on the slide can be processed using techniques such as immunohistochemical staining. Flow of reagents within the chamber can be laminar and highly uniform across the sample surface to achieve staining that is free of gradients. The sample can be imaged prior to, during, or after any given processing step. Methods for staining and imaging a sample can be implemented through one or more rounds of labeling, label removal or erasure and imaging. Samples can be imaged many times to achieve very high multiplexing levels. Samples can be placed on an imaging apparatus at various times and removed from the imaging apparatus for certain steps.

Abstract: An improved gap sub assembly that can withstand the rigors of directional drilling, while still being cost effective and easy to deploy at the drill site. Embodiments can be assembled by sliding a mandrel into a housing without any threading or clocking, filling the gap between the housing and mandrel with an electrically isolating material, and curing the electrically isolating material to mechanically couple the housing and mandrel. In some embodiments, the interior surface of the housing and the outer surface of the mandrel comprise a plurality of complimentary axial sections having staggered diameters so that a constant dielectric gap is maintained. In some embodiments, the interior surface of the housing and the outer surface of the mandrel comprise non-overlapping right- and/or left-handed helical grooves that, when filled with a cured electrically insulating material, forms a complex 3D shear resistance mechanism optimized to resist torsion or twisting.

Abstract: An improved MWD system for drilling unconventional wells. Embodiments provide a particular combination of sensors in a specific arrangement in order to provide a system expressly designed for drilling unconventional wells. By minimizing modularity to reduce the need for redundant/duplicated components, including only sensors specifically needed for unconventional wells, and by separating long-life components such as sensors from components requiring more frequent maintenance or service such as batteries, the components can be more efficiently combined into a BHA sensor assembly having the shortest possible length.

Abstract: Geophysical measurement system employed during the drilling of a well borehole. The system employs a reference clock disposed within equipment at the surface of the earth and a borehole assembly which houses a downhole clock and at least one sensor. The borehole assembly is operationally connected to a drill string, which advances the borehole. At least one synchronization shuttle apparatus containing a shuttle clock is conveyed downhole to the borehole assembly to synchronize the borehole clock with the reference clock. Reference and borehole clock synchronization is maintained at one millisecond or less over a period of days. Outputs from the reference clock and borehole clock and sensor are combined to obtain a measure of a geophysical parameter of interest. Although the measurement system is particularly applicable to seismic-while-drilling measurements, it can be used in a wide variety of clock driven geophysical measurements.
