... are often not imaged properly by the available seismic data due to resolution limits. These features sometimes important to understand for supporting well planning and avoiding drilling hazards. This study demonstrates how ConocoPhillips uses an inhouse proprietary technology to improve seismic resolution...

... 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...

... of the water imbibition/oil recovery dynamics and geological controls is in demand. In this paper, a multiscale imaging technique that covers cm- to nm-scale, i.e., core to pore scale, integrating neutron radiography, micro-CT, and SEM is applied to investigate the water imbibition depth and rate and the cause...

... and microstructure unaffected. Samples of the Tuscaloosa Marine Shale were cleaned by Soxhlet extraction using two conventional solvent mixtures of 80% toluene/20% methanol and 80% dichloromethane/20% methanol. Scanning electron microscopy imaging was performed on the same areas of the samples before and after...

... 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 in directional grain...

.... In this work, this process and its controlling factors are investigated through a comparative study of three shale samples that have different types of pore systems and wettability. An integrated method of imbibition and multiscale imaging was applied, and a modified oleic tracer that can better represent oil...

... Abstract Electron tomography (ET) imaging provides nanometer-scale measurements of the structure of solid samples. ET, with an appropriate reconstruction workflow, provides significant insight into a variety of shale properties including structure, fluid transport and reaction. Despite...

... Abstract The focused-ion-beam scanning electron microscopy (FIB-SEM) technology allows imaging of nano-porous tight reservoir rock samples in 3D at a resolution up to 3 nm/voxel. However, the quality and efficient segmentation of FIB-SEM images is still a complicated and challenging task...

... and horizontal sections. This provides not only velocity/image control in the overburden and target, but also high-resolution images within the frac zone from the horizontal receivers. Another advantage of DAS VSP, if the fiber is permanently installed behind casing, is that the receiver locations are fixed...

...-flooding and subsequent cryogenic preservation, three sub-samples were taken, representing the upstream, midstream, and downstream portions of the core plug sample. Images were acquired at various magnifications and analyzed using multiple image analysis techniques to identify 1) fluid type (oil, brine), 2...

... 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...

... Abstract Orthorhombic model building and depth imaging can provide information uplift in several ways over more simplistic kinematic models. For unconventional onshore seismic projects time processed results are typically used to suggest a smooth velocity function to attempt to correctly...

... Abstract Micro Computed Tomography (microCT) of cores yields valuable information about rock and fluid properties at pore-scale for conventional rock and at rock heterogeneity scale for unconventionals. High levels of uncorrected X-ray scatter in CT data leads to strong image artifacts...

... Summary We propose azimuthal plane-wave destruction seismic diffraction imaging workflow (AzPWD) to efficiently emphasize small-scale features associated with subsurface discontinuities such as faults, channel edges, fracture swarms, etc., and to determine their orientation by properly...

For a number of the stages here imaged, MS events do not extend as far downward as compared to other downhole measurements, possibly due to ductile zone interactions.

We observed good agreement between bulk rock data and digital rock analysis with respect to organic matter volume. Multiple resolution imaging was key in matching porosity visible in SEM with porosity from GRI...

... Summary The physical properties of shale are fundamentally controlled by its microstructure; however, shale is problematic due to microstructural heterogeneity that can exist across multiple scales. This creates difficulty in determining a representative sample size for imaging as well...
