Horizontal Bedding Shale Geostress Calculation Method

Horizontal Bedding Shale Geostress Calculation Method

Received: August 15, 2016 Revised: January 11, 2017 Accepted: February 14, 2017 Abstract: Background: Since the fragile anisotropy of shale, it is difficult to carry out laboratory experiments of geostress by shale cores. The existing geostress calculation model that is based on the homogeneous hypothesis also cannot meet the accuracy requirement. Therefore, it is necessary to establish the new...

Calculation of Bedding Angles Inclination from Drill Core Digital Images

In this paper, we describe a new technique for the automatic orientation of bedding in drill core from digital images. Images are planar pictures of the drill core, and we show that it is possible to determine layer orientation without rotating the core on the full circumference. More precisely, we show that angle information can be extracted by applying image processing and a mathematical desc...

Bedding out

As I write these words, thick snow blankets my lawn and my Potentilla is badly frosted, but you know, we gardeners are never gloomy for long. We know, as we toast our muffins and stir our cocoa, that now is the time to plan next Summer's garden. Of course, with so many gardening programmes on the television nowadays, its quite easy to produce a colourful display. Almost too easy, for the boring...

The Calculation of Horizontal Accelerations from Seismoscope Records by Ronald

The seismoscope is a simple instrument designed originally to give a largely qualitative indication of the strong ground motions produced by an earthquake. It consists of a smoked watch glass attached to a two-degree-of-freedom pendulum with a period of 1⁄4 sec and damping about 10 per cent of critical; a pen records the pendulum motions on the watch glass. One point on the displacement spectru...
