Abstract: A molecular factor computing sensor for use in a subterranean well can include a thermal detector, a layer of an electromagnetic energy absorptive composition, and an electromagnetic energy source. The thermal detector is sensitive to electromagnetic energy from the electromagnetic energy source and absorbed by the electromagnetic energy absorptive composition. A method of identifying at least one chemical identity of a substance in a subterranean well can include positioning at least one molecular factor computing sensor in the well, and the molecular factor computing sensor outputting at least one signal indicative of the chemical identity of the substance. A system for use with a subterranean well can include at least one molecular factor computing sensor that outputs a signal indicative of a chemical identity of a substance in the well. The substance flows between an earth formation and a wellbore that penetrates the formation.

Abstract: Methods and systems for mitigating annular pressure buildup in a wellbore are provided. An example method comprises introducing a treatment fluid into an annulus of the wellbore, wherein the annulus has an annular pressure, and wherein the treatment fluid comprises an aqueous base fluid and a nanoporous metal oxide. The method further comprises allowing or causing to allow at least a portion of the treatment fluid to remain in the annulus; and allowing or causing to allow the annular pressure to increase thereby inducing at least a portion of the aqueous base fluid to enter into an interior volume of the nanoporous metal oxide.

Abstract: Optical sensors having one or more soluble coatings thereon are used to detect the presence of a degrading fluid. In a generalized embodiment, the fiber optic sensor includes a fiber optic cable having two strain sensor positioned therein. A soluble layer is positioned over one of the strain sensor. Due to the presence of the soluble layer, the covered strain sensor optically responds differently than the other strain sensor to changes in pressure, strain and temperature. In the presence of a degrading fluid, the soluble layer degrades and ultimately dissolves, thereby changing the optical response of the previously covered strain sensor. When the soluble layer is dissolved, the strain induced by the soluble layer relaxes, thus causing a wavelength shift in the signal of the grating. By monitoring the wavelength shifts of both strain sensors, the fiber optic sensor acts as a detector for the presence of the degrading fluid.
