Recent attention has focused on the in situ immobilization of uranium by stimulation of dissimilatory metal-reducing bacteria (DMRB). The objective of this work was to investigate the effectiveness of this approach in heterogeneous and structured por

The major ore minerals in black shale-hosted copper deposits typically have a zoned distribution. In this paper a numerical model that couples the processes of chemical reaction and interdiffusion of metals and sulfur is applied to reproduce the patt

The smectite-to-illite reaction (illitization) was examined in a dilute suspension of Wyoming bentonite in the presence of oxalate and acetate. Experiments were performed using fluidsampling apparatus at 200°C, 50 MPa, in which progressive changes i

The importance of precipitation rate as an effective control on illite and kaolanite formation during diagenesis has been examined by measuring precipitation rates, from Al fluid concentration, in a Dickson fluid-sampling vessel at 160°-250° and 50

Illite and illite-smectite, with various morphologies, have been formed on quartz grains by precipitation from solution following dissolution of amorphous Al/Si gels at 150-350 degrees C and 0.75-1.0 kbar (75-100 MPa). Initial solutions include deion

Experiments to explore the dissolution behaviour of Pb-rich orthoclase (1% PbO) and quartz have been carried out in the presence of pH buffered and unbuffered potassium acetate and lithium acetate solutions at 150°C and 50 MPa (500 bars). In pH-unbu

A process-based model relevant to landfill and anaerobic digesters was developed, which included a novel approach to biomass transfer between a cellulose-bound biofilm and biomass in the bulk liquid. Model results highlighted the significance of the

Uranium extraction, processing and storage have resulted in a legacy of uranium-contaminated groundwater aquifers worldwide. An emerging remediation technology for such sites is the in situ immobilization of uranium via biostimulation of dissimilator

A low frequency passive seismic experiment conducted over an onshore carbonate oilfield in Abu Dhabi observed a narrow band of low frequency (2.5 – 2.8 Hz) signals over both the oil reservoir and the water saturated zone (Ali et al., 2007). The pos
