Abstract:

A test site for CO2 geological storage is situated in Hontomín (Burgos, northern Spain) with a reservoir rock that is mainly composed of limestone (80-85%) and sandstone (15-20%). The reservoir rock is a deep saline aquifer that is covered by a very low permeability formation which acts as a cap rock. During and after CO2 injection, since the resident groundwater contains sulfate, the resulting CO2-rich acid solution gives rise to the dissolution of carbonate minerals (calcite and dolomite) and secondary sulfate-rich mineral precipitation (gypsum or anhydrite) may occur. These reactions that m

Abstract:

Deep geological repositories (DGR) are considered an effective long-term solution for radioactive waste disposal. Sedimentary (argillaceous formations) and crystalline rocks are currently under investigation worldwide as potential host formations for DGR. Their low porosity (<1-2 %) and very low hydraulic conductivity result in diffusion-dominated solute transport. There is a need to investigate their diffusion properties in detail, the long-established diffusion methods do not allow an evaluation of the spatial relationship between tracers and the characteristics of the geological medium.

Abstract:

A basin analysis of the Oligocene Porter Group rocks in Castle Hill Basin, Canterbury, was completed. The Porter Group contains the Coleridge Formation which comprises a lower sandstone unit and an upper micritic limestone unit, and the Thomas Formation which consists of biosparite limestone and interbedded tuffs. Basin analysis provided evidence that the Coleridge Formation lower sandstone unit was deposited in an inner shelf setting based upon its moderate sorting, large grain size range, laterally continuous geometry and lack of bedforms due to intense bioturbation.

Abstract:

SummaryThe displacement of oil from reservoir rock pore spaces is a function of many interacting variables, amongst which the reservoir wetting state has been shown to be one of the important affected by the rock lithology, oil chemistry and brine salinity. A finding from previous research says that the injection brine into oil saturated core plug increased oil recovery. Based on this the objective of this master thesis is to investigate the effect of brine concentration on flow properties in two types of carbonate rocks for enhanced oil recovery (EOR) through imbibition and water flooding pro

Abstract:

Sedimentary rocks are characterized with very low permeability (in the order of 10-22 m2), low diffusivity, a possible self-healing of fractures, and a good capacity to retard radionuclide transport. In recent years, sedimentary rocks are investigated by many research groups for their suitability for the disposal of radioactive waste. Development of deep geologic repositories (DGRs) for the storage of radioactive waste within these formations causes progressive modification to the state of stress, to the groundwater regime, and to the chemistry of the rock mass.

Therefore, target unconfined compressive strengths of the study specimens ranged between 60 psi to 850 psi. A simulated limestone material was developed based on over 200 cylinders ca

Given that the near surface horizontal stress conditions in Southern Ontario are uniquely high (σH/σV = 4-6 to depths of 200m; Lo, 1978), it can be expected that sla

Es presenta per a cada espècie una descripció elaborada a partir del material recol•lectat, i es relacionen les localitats on s’ha trobat cada tàxon. Es consideren 41 espècies com a nova aportació a la flora de les Illes Balears,10 per a Mallorca i 67 per a Cabrera. S’estudia el paper dels líquens i altres litobionts en el procés de meteorització de les roques calcàries, a partir de les anàlisi de les aigües d’escorriment superficial sobre tres parells de roques calcàries, estudian

Abstract:

Traditionally New Zealand ecological research has focused on nature outside of cities, however, as with global trends, there is now more interest being given to the ecological functioning of cities and the potential they may hold for protecting native biodiversity. Traditionally, efforts to maintain biodiversity in urban areas have been restricted to remnants of native vegetation and restoration activities. Little attention has been given to how native biodiversity could be woven into the urban fabric in an ecologically meaningful way. One option, that is receiving much attention overseas, is

Abstract:

La prise de conscience de la communauté internationale et la convergence des données scientifiques autour du réchauffement climatique confirment l'urgence de déployer des technologies pour réduire les émissions de gaz à effet de serre. Cependant, ces gaz peuvent s'échapper des réservoirs géologiques profonds et migrer vers les aquifères sus-jacents et la surface. Il est donc nécessaire de mettre en place des systèmes de surveillance du stockage géologique du CO2 pour détecter ces éventuelles fuites et évaluer leur importance et leur impact sur la qualité de l'eau des aquifères.

Abstract:

M.Sc.<br>Certain carbonate bearing formations in the Paleoproterozoic Pretoria Group and its Griqualand West equivalent exhibit remarkable geochemical and stable isotopic signatures. The 8'3Ccarb isotopic signatures from the Duitschland and Silverton Formations exhibit large positive excursions, which seemingly coincide with a significant increase in atmospheric oxygen between 2.4 and 2.0 Ga. The Duitschland Formation with its distinctive basal unconformity is composed primarily of limestone and dolomite units, interbedded with two compositionally different shale units and quartzite.

Abstract:

The primary objective was to predict the relative storage capacity of carbonate rocks relevant for carbon dioxide sequestration. To achieve this, a detailed pore scale characterization of model carbonate rocks, Indiana Limestone and Pink Dolomite, was conducted utilizing micro-computed tomography (microCT) data using pore network modeling and invasion percolation simulations. For the first time in literature, Pink Dolomite’s pore space characteristics were analyzed. A secondary objective was to compare thresholding techniques as applied to carbonates which exhibit dual porosity (porosity at m

Abstract:

Quick and accurate measurements of size distribution are essential for managing fragmented rock and other materials. Various fragmentation measurement techniques are available and used by industry/researchers but most of the methods are time consuming and not precise. WipFrag is an automated image based granulometry system that uses digital image analysis of rock photographs and video tape images to determine grain size distributions. WipFrag images can be digitized from fixed video cameras in the field, or using roving camcorders. Photographic images can be digitized from slides, prints or ne

Abstract:

Two gigantic landslides in carbonate sequences were studied through a combination of remotely sensed datasets and detailed field investigation. Field investigations supplemented the remote analysis at both sites. The work presents the first detailed documentation of the Seymareh (Saidmarreh) landslide, Zagros Mountains, Iran, which is shown to be the largest known rock avalanche in the world and the largest known landslide of any type on the Earth’s land surface. Volume of the Seymareh rock avalanche (38 Gm³) was previously underestimated by nearly 50 percent. The failure mode was complex
