Total rock porosity is a key parameter in a wide range of disciplines from petroleum to civil and mining engineering. Porosity is particularly important in petroleum engineering applications, e.g., from estimation of hydrocarbon in place to prediction of geomechanical properties. Conventional techniques used to measure the total porosity, i.e., mercury intrusion, nitrogen physisorption, focused ion beam–scanning electron microscopy (FIB–SEM), nuclear magnetic resonance (NMR) spectroscopy, gas porosimetry, and X-ray micro-/nano-computed tomography (micro-CT), have yielded inconsistent results for unconventional shale gas samples. A new robust yet practical method is thus required for measuring total porosity in tight formations to be added to the toolbox of the porosity measurement. We propose and develop here a new technique using the concept of heat transfer in porous media. This new heat technique route (HTR) was tested on a highly homogeneous Gosford sandstone benchmark to evaluate its reliability and ...

A new constitutive model for intact rock is presented recognising that rock strength, stiffness and stress–strain behaviour are affected by the size of the rock being subjected to loading. The model is formulated using bounding surface plasticity theory. It is validated against a new and extensive set of unconfined compression and triaxial compression test results for Gosford sandstone. The samples tested had diameters ranging from 19 to 145 mm and length-to-diameter ratios of 2. The model captu...

Abstract The physico-chemical processes of water adsorption into water saturated shale rocks have been extensively studied in the past. However, the physico-chemical processes of water uptake into partially saturated shales, such as water loss to fractured organic-rich shales during hydraulic fracturing, are poorly understood which in turn has raised serious technical and environmental concerns. Therefore, we ran a series of experiments on partially saturated calcareous shale samples, with measu...

Porosity plays a clearly important role in geology. It controls fluid storage in aquifers, oil and gas fields and geothermal systems, and the extent and connectivity of the pore structure control fluid flow and transport through geological formations, as well as the relationship between the properties of individual minerals and the bulk properties of the rock. In order to quantify the relationships between porosity, storage, transport and rock properties, however, the pore structure must be meas...

Easier access to X-ray microtomography (μCT) facilities has provided much new insight from high-resolution imaging for various problems in porous media research. Pore space analysis with respect to functional properties usually requires segmentation of the intensity data into different classes. Image segmentation is a nontrivial problem that may have a profound impact on all subsequent image analyses. This review deals with two issues that are neglected in most of the recent studies on image seg...

The dynamic distribution of thermal conditions present in saturated near-surface sediments have been widely utilised to quantify the flow of water. A rapidly increasing number of papers demonstrate that heat as a tracer is becoming an integral part of the toolbox used to investigate water flow in the environment. We summarise the existing body of research investigating natural and induced heat transport, and analyse the progression in fundamental and natural process understanding through the qua...

The ability to understand and predict how thermal, hydrological, mechanical and chemical (THMC) processes interact is fundamental to many research initiatives and industrial applications. We present (1) a new Thermal–Hydrological–Mechanical–Chemical (THMC) coupling formulation, based on non-equilibrium thermodynamics; (2) show how THMC feedback is incorporated in the thermodynamic approach; (3) suggest a unifying thermodynamic framework for multi-scaling; and (4) formulate a new rationale for as...

Abstract Gas shales have a complex pore structure. Mechanisms of gas storage in the gas shale pore system are in two ways, free gas and sorbed gas. The nanometer scaled pore systems of gas shale reservoirs have a prominent contribution for gas storage, especially for adsorbing gas onto their surfaces. In this study three different methods of low pressure nitrogen adsorption, mercury porosimetry and gas expansion were used for pore structure characterization of gas shales. Mercury porosimetry and...

Abstract null null The role of surface geometry and its evolution during shearing process on the hydromechanical behaviour of rock discontinuities has long remained an open question for geologist. During the shearing process, only a fraction of discontinuity is in contact and the actual stresses on these contacts are considerably greater than nominal stresses. However, measuring the contact area during shearing process has been a significant experimental challenge due to difficulties in detectio...

Abstract null null The challenge associated with large-scale hydrogen storage is a pertinent one to achieve a hydrogen economy. The increasing global demand for clean and green energy is the driving force to propel such an economy. Furthermore, hydrogen is also considered an alternative energy source compared to fossil fuel as a clean energy alternative. Hydrogen geo-storage in a deep saline aquifer, depleted oil and gas reservoirs can resolve this challenge. We assess the potential of a saline ...

Abstract Despite significant advances in micro-scale measurement techniques for investigations in subsurface energy-bearing geomaterials, they have been unable to incorporate subsurface geomechanical conditions such as in-situ stresses in their applications. To overcome such lacking, we designed a novel high-pressure shear cell capable of measuring chemo-thermo-mechanical behaviour of actual (not synthetic) geomaterials by allowing application of critical stresses while simultaneously being expo...

Abstract The conventional techniques cannot accurately predict the multiphase flow behaviour in clay rich low permeability rocks. This is particularly important in applications such as hydraulic fracturing where fluid uptake into low permeability rocks is of interest. This inability has given rise to the use of fractal-based estimation of petrophysical properties of such rocks. The concept of fractal theory revolves around the fractal dimension ( D f ) representing the entire pore structure whic...

The formation of compaction bands in porous brittle rocks such as sandstones and carbonates has a significant impact on the localization mechanisms preceding earth and planetary surface instabilities such as earthquakes, landslides, and plate boundary faults. The micromechanics underpinning the dynamics of the formation of compaction bands and its effect on alteration of pore fluid pathways are not yet fully understood. The current study seeks to understand the mechanical properties of compactio...

Abstract Frictional behaviour of joints/faults is of great importance in many geo-engineering applications across different scales. It is known that the joint surface roughness is one of the critical parameters controlling the frictional behaviour of rock joints. While nominal normal and shear stresses acting across the joint asperities are calculated based on overall shearing area, the actual normal and shear stresses can be much greater due to smaller actual contact area. The actual contact ar...

Porosity is important in the assessment of gas shale reservoirs and has been widely tested as a basic characteristic of shale. Different test methods were employed to test the porosity, yet inconsistencies were found among the samples, testing methods, and researches in the Longmaxi Formation of the Sichuan Basin. In this paper, in order to determine the source of the inconsistencies, seven test methods are undertaken and the test results are compared intensely. The results show that the inconsi...

Abstract Despite extensive research conducted on North American and Chinese shale plays, fairly little has been reported on Australian gas-shales and no comparative study exists to assess their complexity associated with their geological setting and mineralogical compositions. We thus performed an extensive set of petrophysical characterizations including mineralogy, porosity, permeability, pore size distribution, fracture system, wettability, adsorption capacity, and mechanical properties of fo...

Abstract The influence of heating followed by cooling on the alteration of the microstructural properties of Harcourt granite was comprehensively investigated utilising X-ray computed tomography (CT) imaging and three-dimensional (3-D) image reconstruction and analysis. Two cooling treatments, rapid and slow cooling, were adopted with preheating temperatures ranging from 25 to 1000 °C. The pore spaces of the thermally-treated specimens were analysed to obtain their porosity and pore connectivity...

Abstract The rate of gas production from coal seam gas reservoirs is highly dependent on coal lithotype, cleat attributes and multiphase flow in cleats. In this paper, we explore and categorize the wettability, roughness data, sorption capacity, and the flow in bright and dull coal lithotypes. The roughness measured on the wall surface of coal fractures indicates different values for each lithotype. Multiphase flow through rough-walled fractures is measured and the pressure variation and relativ...
