Embodiment Construction
[0031] The following description of exemplary embodiments refers to the accompanying drawings. The same reference numbers in different drawings identify the same or similar elements. The following detailed description does not limit the invention. Rather, the scope of the invention is defined by the appended claims.
[0032] Reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the disclosed subject matter. Thus, appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout the specification are not necessarily referring to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more embodiments.
[0033]As used herein, the term "index" refers to a measurement-derived value that describes...

Abstract
A method for estimating a fracability index of a geographic location includes determining a structural index and a mineral composition index of a geological sample extracted from a geographic location, and estimating the geographic location based on the structural index and the mineral composition index. The fracability index of the location. The texture index may be a texture-related measure, such as texture size or angularity, or a pore space-related measure, such as pore area, diameter, aspect ratio, and perimeter, or statistical data associated with these measurements. In certain embodiments, determining the mineral composition indicator includes detecting in the geological sample at least one prevalent organic proxy indicator, such as vanadium, iron, uranium, thorium, copper, sulfur, zinc, chromium, nickel, cobalt, lead, and molybdenum. Determining mineral composition indicators may also include detecting one, both, or all of the prevalent siliciclastic, carbonate, and clay.
Description
technical field [0001] Embodiments of the subject matter disclosed herein relate generally to the field of oil and gas exploration and extraction. In particular, embodiments disclosed herein relate to apparatus, methods, and systems for determining geomechanical properties of rock and adjusting oil and gas recovery operations in response to those measurements. Background technique [0002] Geophysical data are useful for various applications such as weather and climate prediction, environmental monitoring, agriculture, mining, and seismology. As the economic benefits of such data have been demonstrated, and additional applications for geophysical data have been discovered and developed, the demand for localized, high-resolution, and cost-effective geophysical data has grown enormously . This trend is expected to continue. [0003] For example, seismic data acquisition and processing can be used to generate sections (images) of geophysical structures beneath the surface (e...
