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 for a geological location includes determining a fabric metric and a mineralogical composition metric for a geological sample extracted from a geological location and estimating a fracability index for the geological location from the fabric metric and the mineralogical composition metric. The fabric metric may be a grain related measurement such as grain size or angularity, or a pore-space related measurement such as pore area, diameter, aspect ratio, and circumference, or statistics associated with such measurements. In certain embodiments, determining the mineralogical composition metric includes detecting a prevalence of at least one organic proxy within the geological sample such as vanadium, iron, uranium, thorium, copper, sulfur, zinc, chromium, nickel, cobalt, lead and molybdenum. Determining the mineralogical composition metric may also include detecting a prevalence of one, two, or all of siliciclastics, 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...
