Paper presented at the SPE/AAPG/SEG Unconventional Resources Technology Conference, June 13–15, 2023
Paper Number: URTEC-3860785-MS
... Abstract A novel diagnostic processing technique called Conductive Fracture Imaging (CFI) was applied to the Hydraulic Fracture Test Site-2 dataset acquired in 2019 in the Delaware Basin, USA. CFI results were delivered independently and subsequently compared to permanently installed fiber...

A microstructural study involving X-ray radiography and SEM imaging was then carried out to investigate the contributions of texture (phase distribution and load bearing fraction) and fabric (anisotropy) to effective anisotropic grain compressibility. The measurements reveal anisotropy...

... remains poorly understood. Here we report on shale samples that have undergone MICP followed by Micro X-ray Computed Tomography (μXCT) and FIB/SEM imaging. μXCT results show that not all regions of the shale samples were accessed uniformly by MICP. Mercury is observed going into fractures and penetrating...
