摘要： The present application relates sensing reactive components in fluids by monitoring band gap changes to a material having interacted with the reactive components via physisorption and/or chemisorption. In some embodiments, the sensors of the present disclosure include the material as a reactive surface on a substrate. The band gap changes may be detected by measuring conductance changes and/or spectroscopic changes. In some instances, the sensing may occur downhole during one or more wellbore operations like drilling, hydraulic fracturing, and producing hydrocarbons.

摘要： The embodiments herein relate to sensors having reactive filter materials for detecting analytes in wellbores. The sensor includes at least one reactive filter material arranged in a flow line, wherein the reactive filter material sorbs an analyte in a wellbore fluid in the flow line; and at least one detector that detects a sorption signal specific to the analyte at at least a first location and a second location of the reactive filter material, wherein the first location is upstream in the flow line relative to the second location. The detector either (1) calculates a balanced measurement corresponding to the presence of the analyte in the wellbore or (2) relays the measurements to a signal processing unit to calculate a balanced measurement corresponding to the presence of the analyte in the wellbore.

摘要： Detection sensitivity of optical computing devices may be improved by utilizing multiple integrated computational elements in combination with one another. Optical computing devices containing multiple integrated computational elements may comprise: two or more integrated computational elements that are identical to one another and optically interact sequentially with incident electromagnetic radiation, such that at least a portion of the photons from the incident electromagnetic radiation optically interacts with each integrated computational element; wherein the sequential optical interaction of the incident electromagnetic radiation with the two or more integrated computational elements increases a detection sensitivity of the optical computing device relative to that obtained when only one of the integrated computational elements is present; and a detector that receives the photons that have optically interacted with each integrated computational element.

摘要： Integrated computational elements having alternating layers of materials may be problematic to configure toward mimicking some regression vectors. Further, they sometimes may be inconvenient to use within highly confined locales. Integrated computational elements containing a quantum dot array may address these issues. Optical analysis tools with an integrated computational element can comprise: an electromagnetic radiation source that provides electromagnetic radiation to an optical pathway; an integrated computational element positioned within the optical pathway, the integrated computational element comprising a quantum dot array having a plurality of quantum dots disposed at a plurality of set array positions; and a detector that receives the electromagnetic radiation from the optical pathway after the electromagnetic radiation has optically interacted with a sample and the integrated computational element. Optical interaction of electromagnetic radiation with the quantum dots at one or more set array positions can substantially mimic a regression vector for a sample characteristic.
