Overpressure prediction in tectonic environments is a challenging topic. The available pore pressure prediction methods are designed to work in environments where compaction is mostly one dimensional and driven by the vertical effective stress applie...

Compaction of diagenetically altered mudstones - Part 1: Mechanical and chemical contributions (2016)
Journal Article
Goulty, N., Sargent, C., Andras, P., & Aplin, A. (2016). Compaction of diagenetically altered mudstones - Part 1: Mechanical and chemical contributions. Marine and Petroleum Geology, 77, 703-713. https://doi.org/10.1016/j.marpetgeo.2016.07.015

At low temperatures, siliciclastic mudstones compact mechanically. Above 70C, where the smectite-to-illite transformation dominates clay diagenesis, they also compact chemically, provided that excess pore water can escape. There are two prevailing co...

Numerical evaluation of mean-field homogenisation methods for predicting shale elastic response (2016)
Journal Article

Homogenisation techniques have been successfully used to estimate the mechanical response of synthetic composite materials, due to their ability to relate the macroscopic mechanical response to the material microstructure. The adoption of these mean-... Read More about Numerical evaluation of mean-field homogenisation methods for predicting shale elastic response.

Stress and pore pressure histories in complex tectonic settings predicted with coupled geomechanical-fluid flow models (2016)
Journal Article

Most of the methods currently used for pore pressure prediction in sedimentary basins assume one dimensional compaction based on relationships between vertical effective stress and porosity. These methods may be inaccurate in complex tectonic regimes... Read More about Stress and pore pressure histories in complex tectonic settings predicted with coupled geomechanical-fluid flow models.

Extracting gas from shale rocks is one of the current engineering challenges but offers the prospect of cheap gas. Part of the development of an effective engineering solution for shale gas extraction in the future will be the availability of reliabl...

Observations of pore systems of natural siliciclastic mudstones (2016)
Book Chapter
Aplin, A., & Moore, J. (2016). Observations of pore systems of natural siliciclastic mudstones. In T. Schäfer, R. Dohrmann, & H. Greenwell (Eds.), Filling the gaps - from microscopic pore structures to transport properties in shales (33-44). Clay Minerals Society. https://doi.org/10.1346/cms-wls-21.3

Grains within siliciclastic muds are deposited either as flocs, in which grains are generally ,10 mm, or as single grains: “sortable silt,” generally .10 mm. When clay-size (,2 mm diameter) particles form .30% of mudstones, pore-size distributions ar... Read More about Observations of pore systems of natural siliciclastic mudstones.
