Geological characterisation of thin-bedded crevasse splay sandstones; outcrop-analogue studies for tough gas reservoir potential

Crevasse splay complexes in floodplain sequences are potential low net-to-gross tough gas reservoirs. The porosity and permeability of these reservoirs is low, but lateral amalgamation by compensational stacking can create extensive lobe-shaped sediment bodies with reservoir potential. The aim of this thesis is to characterize the development of...

Weathering of fluvial sands as a compositional linear process: A new modeling approach

Geological data is often compositional (i.e. positive and sum to unity). The constrained nature of compositional data can lead to severe problems during data analysis. Transforming from the simplex to centered log-ratio (CLR) space can solve these problems, converting constrained non-linear processes into unconstrained linear processes ...
