Overview

What is he best known for?

The fields of study he is best known for:

  • Geometry
  • Composite material
  • Optics

His scientific interests lie mostly in Anisotropy, Mineralogy, Composite material, Ultrasonic sensor and Geometry. The Seismic anisotropy research Colin M. Sayers does as part of his general Anisotropy study is frequently linked to other disciplines of science, such as Distribution function, therefore creating a link between diverse domains of science. His study in Mineralogy is interdisciplinary in nature, drawing from both Azimuth, Characterization, Transverse isotropy, Fracture and Reflection.

His work on Porous medium, Shear waves and Porosity as part of his general Composite material study is frequently connected to Context, thereby bridging the divide between different branches of science. The concepts of his Ultrasonic sensor study are interwoven with issues in Neutron diffraction, Optics and Austenite. As part of one scientific family, he deals mainly with the area of Geometry, narrowing it down to issues related to the Spherical harmonics, and often Vertical seismic profile.

His most cited work include:

  • Seismic anisotropy of fractured rock (637 citations)
  • Microcrack-induced elastic wave anisotropy of brittle rocks (439 citations)
  • A simple technique for finding effective elastic constants of cracked solids for arbitrary crack orientation statistics (197 citations)

What are the main themes of his work throughout his whole career to date?

Colin M. Sayers focuses on Anisotropy, Mineralogy, Seismology, Pore water pressure and Geotechnical engineering. The Anisotropy study combines topics in areas such as Shear and Azimuth, Geometry. His Geometry research incorporates elements of Series expansion and Spherical harmonics.

His Mineralogy research integrates issues from Oil shale, Seismic wave, Amplitude versus offset, Isotropy and Reflection. As a member of one scientific family, he mostly works in the field of Pore water pressure, focusing on Drilling and, on occasion, Petroleum engineering, Casing and Borehole. His Stress research extends to the thematically linked field of Geotechnical engineering.

He most often published in these fields:

  • Anisotropy (32.12%)
  • Mineralogy (19.34%)
  • Seismology (17.52%)

What were the highlights of his more recent work (between 2011-2021)?

  • Anisotropy (32.12%)
  • Seismology (17.52%)
  • Azimuth (10.95%)

In recent papers he was focusing on the following fields of study:

Colin M. Sayers spends much of his time researching Anisotropy, Seismology, Azimuth, Mineralogy and Oil shale. Colin M. Sayers works in the field of Anisotropy, focusing on Elastic anisotropy in particular. The various areas that Colin M. Sayers examines in his Seismology study include Structural basin, Inversion, Horn and Drilling.

His work carried out in the field of Azimuth brings together such families of science as Amplitude, Geophysics and Fluid dynamics. His Mineralogy study incorporates themes from Isotropy, Transverse isotropy, Reflection coefficient and Elastic modulus. His Oil shale research focuses on Kerogen and how it relates to Geotechnical engineering.

Between 2011 and 2021, his most popular works were:

  • The effect of kerogen on the elastic anisotropy of organic-rich shales (116 citations)
  • The effect of anisotropy on the Young's moduli and Poisson's ratios of shales (75 citations)
  • Seismic characterization of naturally fractured reservoirs using amplitude versus offset and azimuth analysis (41 citations)

In his most recent research, the most cited papers focused on:

  • Geometry
  • Composite material
  • Optics

The scientist’s investigation covers issues in Anisotropy, Seismology, Mineralogy, Azimuth and Amplitude versus offset. Colin M. Sayers is studying Seismic anisotropy, which is a component of Anisotropy. He has included themes like Pore water pressure, Permeability and Petroleum engineering in his Seismology study.

The study incorporates disciplines such as Isotropy, Transverse isotropy and Reflection coefficient in addition to Mineralogy. His Reflection coefficient research includes elements of Amplitude, Reflection, Geometry and Shear. His research in Kerogen tackles topics such as Geotechnical engineering which are related to areas like Drilling.
