Open AccessEmpirical rock physics relationships on carbonate dry-frame elastic properties
Laboratory tests were conducted to analyze the ultrasonic velocity response to the pressure change in dry carbonate rocks from the Weyburn oilfield, Canada. Twenty-four samples are from seven wells with helium...

Open AccessEvaluation of the geothermal potential of the western Snake River Plain based on a deep corehole on the Mountain Home AFB near Mountain Home, Idaho
A geothermal exploration corehole was drilled to a total depth of 1821.5 m on the Mountain Home Air Force Base near Mountain Home, Idaho. The corehole was used to collect an unusually large amount of data, inc...

Correction to: Effective Stress Coefficient for Seismic Velocities in Carbonate Rocks: Effects of Pore Characteristics and Fluid Types
Due to an unfortunate oversight the sentence “Also, the fact that some carbonates, such as siliciclastic rocks, may be less sensitive to compaction adds another level of complexity.” is not given correctly.

Effective Stress Coefficient for Seismic Velocities in Carbonate Rocks: Effects of Pore Characteristics and Fluid Types
The concept of effective stress is key for understanding the dependence of rock elastic and compaction behaviors on stress and pore-fluid pressure. Previous studies on the concept largely used data acquired on...

Extreme hydrothermal conditions at an active plate-bounding fault
Extreme temperatures and fluid pressures are measured, and their causes modelled, in a borehole into the Alpine Fault, where an earthquake rupture is expected within the next few decades.

Open AccessInitial seismic observations from a deep borehole drilled into the Canadian Shield in northeast Alberta
The availability of a deep borehole in northeastern Alberta provides an unprecedented opportunity to study the in situ metamorphic craton rocks. This borehole reaches a depth of 2.4 km, with 1.8 km in the cry...

Elastic Anisotropy of a Metamorphic Rock Sample of the Canadian Shield in Northeastern Alberta
The presence of fractures and textures cause metamorphic rock masses to be seismically anisotropic. Neglect of this anisotropy in the processing of field seismic data causes problems in the final reflection im...

An integrative geothermal resource assessment study for the siliciclastic Granite Wash Unit, northwestern Alberta (Canada)
This study explores the siliciclastic Granite Wash Unit in northwestern Alberta as a potential geothermal reservoir. The approach covers regional 3D structural geological modelling of a 90 km × 70 km area base...

The Transition Between the Scale Domains of Ray and Effective Medium Theory and Anisotropy: Numerical Models
The anisotropy of a periodically layered isotropic medium is numerically modeled in order to study the effect of the scale of heterogeneity on seismic observations. An important motivation is to delineate the ...

Three-dimensional stress-relief displacements from blind-hole drilling: a parametric description
Optically-based interferometric techniques are finding increased application to the quantitative determination of near surface stress states. Unlike the standardized strain-gage method of hole drilling, howeve...
