    Abstract: The present disclosure relates to delivery and release systems, such as core-shell particles. An exemplary composition according to the disclosure can include a carrier element forming an outer shell that defines an inner core. The core can include a reactive agent that is adapted to react with the shell, particularly at an inner interface of the shell with the core materials. The reaction can provide an inside-out degradation of the shell and release of one or more materials therein. The reactive agent may be separated from the shell, such as using a phase change material (PCM). Upon reaching specific environmental conditions, the PCM can change so as the release the reactive agent for reaction with the shell. The systems can be used in various methods to deliver a material to various environments, including underground reservoirs.

    Abstract: The present disclosure relates to cementitious fluids comprising additives configured to form a permeable cement matrix after curing of the cement. The cementitious fluids can comprise a cementitious medium (e.g., a cement slurry) with a plurality of fibers dispersed therein. The fibers can be hollow, can be porous, and can be degradable. The cementitious fluid particularly can be used in methods of stimulating hydrocarbon bearing formations. Specifically, the cementitious fluid can be injected into the formation to form or enlarge a fracture, and the fluid can be cured to form the permeable cement matrix, said permeability arising from a loosely assembled tubular network and/or passages remaining after degradation of the fibers.

    CPC classification number: G01N21/534

    Abstract: The present disclosure provides sensing systems and methods that are useful for monitoring materials (e.g., cement) via light diffusion to identify characteristics thereof and changes therein. The systems can utilize a light source, a light sensor, and light transmitting members combined with the material to be monitored. In use, light from the light source can be allowed to scatter through the material via the light transmitting members for detection by the light sensor. The data regarding the light transfer can be transmitted utilizing a communication interface and can be analyzed using data processing equipment. The systems and methods may particularly be utilized in monitoring the reinforcing cement positioned between the casing and the formation in an oil well.
