Abstract: A subterranean formation penetrated by a wellbore is treated by introducing into the wellbore an encapsulated material comprising an encapsulating component formed from a regenerated ionic-liquid-dissolved compound and an active component that is encapsulated by the encapsulating component. The encapsulating material is then allowed to release the active component into the formation. In another treatment method, an encapsulated material comprising an encapsulating component and an active component that is encapsulated by the encapsulating component are introduced into the wellbore. The encapsulating component is degradable when subjected to electromagnetic radiation having a frequency of from about 300 MHz to about 300. The encapsulated material is then subjected to electromagnetic energy in the frequency range of from about 300 MHz to about 300 GHz to degrade the encapsulating component and facilitate the release the active component into the formation.

Abstract: A methodology improves sampling and characterization of heterogeneous, unconventional hydrocarbon-bearing regions. The methodology is designed to integrate consistently across measurements and scales. Additionally, the methodology involves characterizing various scales, such as regional-scale heterogeneity, wellbore-scale heterogeneity, core-scale heterogeneity, sample-scale, and pore-scale heterogeneity. The results are integrated across the multiple scales based on results obtained from the characterization of the scales. The methodology further comprises determining data propagation across the multiple scales in a hydrocarbon-bearing region.

Abstract: An aspect of a formation may be estimated by placing a nuclear spectroscopy tool including a neutron source and a gamma ray detector into a borehole and performing a plurality of environmental measurements. Neutrons are emitted from the nuclear spectroscopy tool such that some of the neutrons generate gamma rays from a formation adjacent the nuclear spectroscopy tool, some of the neutrons generate gamma rays from elements within the nuclear spectroscopy tool and some of the neutrons generate gamma rays from an element in the drilling mud. An energy spectrum of gamma rays induced by the emitted neutrons can be detected with the tool. The detected gamma-ray energy spectrum can be analyzed using a combination of standard spectra, where the shape of at least one of the standard spectra can be varied based on the environmental measurements to account for the environment's effects on gamma-ray spectra.

Abstract: A method for estimating an aspect of a formation using a nuclear spectroscopy tool includes placing a nuclear spectroscopy tool into a borehole and emitting neutrons such that some of the neutrons generate gamma rays from a formation adjacent the nuclear spectroscopy tool and some of the neutrons generate gamma rays from elements within the nuclear spectroscopy tool. An energy spectrum of gamma rays induced by the emitted neutrons can be detected. The energy spectrum includes a background having a plurality of measured spectral components. A background ratio between at least one spectral component of the background and another measured spectral component can be determined or estimated in accordance with environmental measurements. The detected gamma ray spectra can be analyzed using a combination of standard spectra and subtracting at least one spectral component of the background in accordance with the background ratio.
