摘要:
Apparatus and systems may operate to enable positron emission imaging with a unitary chamber body having an open end that defines a hollow interior portion shaped to completely contain a flexible sleeve that is used to cover a core sample when the sleeve is seated within the hollow interior portion. An end cap may be formed to engage the open end of the chamber body, which is configured to attenuate gamma rays approximately eight times less than stainless steel, while supporting a pressure differential of at least 3 MPa between the chamber inlet and the outlet when fluid carrying a radioactive tag to generate the gamma rays flows through the hollow interior portion and the core sample via the inlet and the outlet. Additional apparatus, systems, and methods are disclosed.

Modeling hydrocarbon flow, from layered shale formations. At least some of the illustrative embodiments are methods including: modeling movement of hydrocarbons through kerogen-related porosity, the movement through a first model volume; estimating a first permeability of a kerogen-rich layer of a layered shale formation based on the modeling; and modeling hydrocarbon production from the layered shale formation. The modeling hydrocarbon production may include: utilizing the first permeability for the kerogen-rich layer of the layered shale formation; and utilizing a second permeability for a kerogen-poor layer of the layered shale formation, the second permeability different than the first permeability. In various cases the modeling of hydrocarbon production is with respect to a second model volume greater than the first model volume.
