Method of determining a value indicative of fracture quality

摘要

Determining a value indicative of fracture quality. At least some of the illustrative embodiments are methods including: obtaining or measuring gas saturation of a formation to create a value indicative of pre-fracture gas saturation; and after a fracturing process measuring gas saturation of the formation to create a value indicative of post-fracture gas saturation; and creating a value indicative of fracture quality based on the value indicative of pre-fracture gas saturation and the value indicative of post-fracture gas saturation.

1. A method comprising:
determining a value indicative of fracture quality by:
releasing neutrons into a formation from a neutron source of a first logging tool, the formation fractured prior to releasing the neutrons;sensing energies of gammas produced by materials in the formation, the sensing by a gamma detector associated with the first logging tool;determining a first value indicative of post-fracture gas saturation based on the gammas; andcreating the value indicative of fracture quality based on the first value indicative of post-fracture gas saturation.
