Shale: Shale breaks into thin pieces with sharp edges. It occurs in a wide range of colors that include red, brown, green, gray, and black. It is the most common sedimentary rock and is found in sedimentary basins worldwide. What is Shale?

Feb 20, 2020 · Drill core shale samples are critical for palaeoenvironmental studies and potential hydrocarbon reservoirs. They need to be preserved carefully to maximise their retention of reservoir...

Dec 1, 2020 · Hydrocarbon production from unconventional shale reservoirs has gained increasing worldwide focus, spurred largely by improvements in production techniques. Nuclear magnetic resonance (NMR) is increasingly being explored …

Jan 11, 2017 · Mineralization can be missed in core but is hard to miss in thin-sections. This post is not about fractures but take some time to familiarize yourself with features you can use to differentiate shear from tension fractures.

© Kimmeridge 2012 - Defining the Core of Shale Plays 5 After extensive drilling and de-risking of a play, it is relatively easy to define the core (see exhibit 6). It is simply the area of the play where wells produce the highest return on capital employed. More specifically, it …

Understanding lithologic variation is an important key for locating hydrocarbon-rich areas (sweet spots) in the Barnett Shale and other shale gas reservoirs. Only a few detailed studies of Barnett Shale core describing lithology, diagenetic, and depositional histories …

Mar 13, 2019 · To accurately reproduce the morphology of multiscale pore structure of the shale core, a novel core-scale reconstructing method is proposed to reconstruct 3D digital-experimental models...

Shale core can be stored in aluminium or fibreglass tubes, capped and sealed, or placed in metal and corrugated plastic trays that have a good size match with the core. For sampling, a hand corer can be used, and the central portion of an intact core would be the best target.

Regardless of where in the world they are being explored, gas shales share some fundamental properties that make them virtually impossible to analyze with conventional core analysis methods or conventional petrophysical models based on log data.

Abstract: Drill core shale samples are critical for palaeoenvironmental studies and potential hydrocarbon reservoirs. They need to be preserved carefully to maximise their retention of...
