Ingrain, Inc. is a multinational digital rock physics laboratory. Co-founded in 2007 by Amos Nur, Ph.D. and Henrique Tono, Ph.D, Ingrain's imaging technology allows it to compute the physical properties and fluid flow characteristics of oil and gas reservoir rocks. Ingrain's advances in 3D imaging technology provide oil and gas companies with comprehensive and accurate measurements of reservoir rock properties including porosity, absolute permeability, electrical conductivity, elastic properties and relative permeability. Ingrain’s financial backers include Energy Ventures, a leading venture capital firm specializing in upstream technology. Wikipedia.

A method is provided for efficiently characterizing rock traversed while drilling a borehole for hydrocarbon reservoir development. A rock sample can be obtained having a provenance of collection linked to a specific region of the borehole, which is scanned to obtain a 2D digital image that is segmented to pixels characterized as pore space and as mineral matrix and defining a boundary between them. A transform relationship, for example, a form of the Kozeny-Carman equation adapted for application to a 2D segmented image environment, can be applied to calculate the estimated value for a target rock property, which can be absolute permeability, relative permeability, formation factor, elasticity, bulk modulus, shear modulus, compressional velocity, shear velocity, electrical resistivity, or capillary pressure, and the estimated value is used to characterize the rock at that region of the borehole. This affords an opportunity to quickly and efficiently develop massive data directly characterizing extended regions of rock, whether traversed by the borehole in this or a related well. Computerized systems, computer readable media, and programs for performing the methods are also provided.

A method includes receiving images of a rock sample. The method also includes modifying a set of voxels related to one or more of the received images by applying a digital pore growing operation that changes non-pore voxels surrounding a pore space to pore voxels, wherein the digital pore growing operation is based at least in part on a predetermined dead oil estimate. The method also includes estimating a property of the rock sample based at least in part on the modified set of voxels.

A method for increasing the accuracy of a target property value derived from a rock sample is described in which the sample is scanned to obtain a three-dimensional tomographic digital image which can be processed to pore space and solid material phases through a segmentation process. A process is used which revises the segmented volume, e.g., by increasing pore space connectivity, in a manner affecting the target property value that would be derived. Another described method increases the accuracy with which a segmented volume represents a material sample having structure not adequately resolved in an original three-dimensional tomographic digital image. Further, a system for performing the processes, and a segmented digital volume which more accurately represents a sample of a porous media, are described.

Methods and systems for cuttings-based well logging, including a method that includes converting measurements of cuttings samples from one or more depth intervals of a wellbore to a concentration percent of one or more elements, determining a one or more minerals of the cuttings samples from the concentration percent and building a mineralogy model for the cuttings sample based at least in part on a gravimetric conversion of the concentration percent of at least some of the one or more elements to a concentration percent of the one or more minerals. The method further includes normalizing the concentration percent of the one or more minerals, computing a photo-electric absorption factor (PEF) of the cuttings samples for each of the one or more depth intervals, and presenting to a user a log of the computed PEF as a function of wellbore depth.

A method is provided to allow characterization of rock or other types of samples using a sliver that is prepared to have a sample and optionally a plurality of thin discrete reference objects encapsulated by hardened encapsulant that surrounds the peripheral edges of the sample and any reference objects. Systems for performing the methods are also provided. An x-ray scannable sliver also is provided as a single unit that has a thin discrete sample and a plurality of thin discrete reference objects encapsulated by hardened encapsulant that encases the peripheral edges of the sample and reference objects.
