Methods for using treatment fluids comprising synthetic silicates in subterranean formations are provided. In some embodiments, the methods may comprise introducing a treatment fluid comprising an aqueous base fluid and a synthetic silicate into a wellbore penetrating at least a portion of a subterranean formation comprising a loss zone; allowing the treatment fluid to displace at least a portion of a first fluid present in the wellbore; and allowing the treatment fluid to at least partially plug the loss zone.

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.

An apparatus, method, and sample vessel for recombining a sample fluid. The sample fluid is received in a sample vessel. Sample parameters are recreated in the sample vessel. The sample fluid is agitated within the sample vessel. Optical measurements of the sample fluid are performed within the sample vessel utilizing one or more optical sensors. A determination is made whether recombination is complete in response to the optical measurements of the sample fluid performed by the one or more optical sensors.
