Abstract: A method for mapping a three-dimensional structure and obtaining information on the condition of said structure. The method includes injecting a plurality of motes into the structure causing the plurality of motes to travel through the one or more channels, the motes including a sensor and a storage, the motes being arranged designed to obtain a sensor-value measured by the sensor and to store the sensor-value in the storage, thus obtaining a time series of measured sensor-values in the storage, retrieving at least part of the plurality of motes from the structure, obtaining from said retrieved motes the time series of measured sensor-values stored in the retrieved motes, thus obtaining a set of measured time series, determining the structure or the condition by comparing the set of measured time series with a simulation.

Abstract: A memristor element is used to create a spectrally programmable optical computing device for use in, for example, a downhole environment. An electromagnetic field is applied across the memristor element in order to alter its spectral properties. In turn, the spectral properties of sample-interacted light optically interacting with the memristor element are also altered. This alteration in spectral properties allows the memristor to be “programmed” to achieve a variety of transmission/reflection/absorption functions.

Abstract: A system and method for monitoring underground drilling in which vibration is monitored by creating a model of the drill string using finite element techniques or finite difference techniques and (i) predicting vibration by inputting real time values of operating parameters into the model, and then adjusting the model to agree with measured vibration data, (ii) predicting the weight on bit and drill string and mud motor speeds at which resonance will occur, as well as when stick-slip will occur, so that the operator can avoid operating regimes that will result in high vibration, (iii) determining vibration and torque levels along the length of the drill string based on the measured vibration and torque at one or more locations, (iv) determining the remaining life of critical components of the drill string based on the history of the vibration to which the components have been subjected, and (v) determining the optimum drilling parameters that will avoid excessive vibration of the drill string.

Abstract: Embodiments provide methods and systems for modeling a proposed geological volume. One such embodiment begins by digitally creating a three-dimensional (3D) model of a geological volume that includes one or more variables, each of which is a mathematical factor in an analysis confidence of one or more sub-volumes of the volume. Next, standardized values for each of the one or more variables are defined. In turn, the analysis confidence, e.g. mined, ore quality, etc., of the one or more sub-volumes is mathematically determined. Finally, the model is updated to include the determined analysis confidence of the one or more sub-volumes.

Abstract: The present disclosure relates to methods and apparatus for determining a viscosity-pressure profile of downhole fluid by measuring the viscosity at several different pressures during a sampling operation. According to certain embodiments, the viscosity may be measured at different times during a sampling operation and used to generate the viscosity-pressure profile. For example, the viscosity may be measured at the beginning of pumping, during filling of a sample chamber, during a pressure-build up period, and while retracting the probe. The measured viscosities may then be employed to determine a profile that represents the change in viscosity that occurs with pressure.

Abstract: A method for managing a live stream of waste stream fluids in which a controller of an applicator unit accesses data indicative of a first concentration of at least one contaminant in a volume of waste stream fluids loaded in the applicator unit, and a contaminant capacity profile indicative of an amount of the at least one contaminant to be applied in the land area. At least a portion of the volume of waste stream fluids loaded in the applicator unit is applied on at least a portion of a land area based on the first concentration of the at least one contaminant in the volume of waste stream fluids and the contaminant capacity profile. The controller generates an updated contaminant capacity profile based at least in part on the volume of waste stream fluids applied on the land area and the first concentration of the at least one contaminant in the volume of waste stream fluids applied to the land area.
