Controlled?source electromagnetics (CSEM) has been used as a de?risking tool in the hydrocarbon exploration industry. Although there have been successful applications of CSEM, this technique is still not widely used in the industry because the limited types of hydrocarbon reservoirs CSEM can detect. In this paper, we apply the concept of...

We perform wave experiments using a vertical shock tube setup. Shock waves are generated by the rupture of a thin membrane. In the test section, the incident pressure waves generate borehole-guided waves along water-saturated samples. The tube is equipped with side wall gages and a mobile pressure probe, so that the attenuation and reflection of...

Controlled-source electromagnetics (CSEM) has been used as a derisking tool in the hydrocarbon exploration industry. We apply the concept of synthetic aperture to the lowfrequency electromagnetic field in CSEM. Synthetic aperture sources have been used in radar imaging for many years. Using the synthetic aperture concept, big synthetic sources...

We report on direct measurements of the magnetic near-field of metamaterial split ring resonators at terahertz frequencies using a magnetic field sensitive material. Specifically, planar split ring resonators are fabricated on a single magneto-optically active terbium gallium garnet crystal. Normally incident terahertz radiation couples to the...

Interferometry by multidimensional deconvolution applied to Controlled-Source Electromagnetic data replaces the medium above the receivers by a homogeneous halfspace, suppresses the direct field and redatums the source positions to the receiver locations. In that sense, the airwave and any other interactions of the signal with the air-water...

This summary provides a brief account of the background, approach, analysis and conclusions of this thesis. Construction is characterized as a high hazard industry which contains a wide range of activities including construction, alteration and/or repair (Michaels, 2010). The organizations involved in construction projects are project owner,...

With interferometry applied to controlled-source electromagnetic data, the direct field and the airwave and all other effects related to the air-water interface can be suppressed in a data-driven way. Interferometry allows for retreival of the scattered field Green’s function of the subsurface or, in other words, the subsurface reflection...

We use interferometry by multidimensional deconvolution in combination with synthetic aperture sources in 3D to suppress the airwave and the direct field, and to decrease source uncertainty in marine Controlled-Source electromagnetics. We show with this numerical study that the method works for very large receiver spacing distances, even though...

Concrete cracking is inevitable, and can be the result of one or a combination of factors such as dry shrinkage, thermal contraction, fatigue, and embedded steel corrosion. The presence of cracks leads to further deterioration, service life reduction of concrete infrastructure, and frequent maintenance and repairs. These challenges can be...

In a traditional AC distribution system, the synchronous frequencies of the generators are coupled with the system frequency, and thus the diesel engines are kept at a constant speed. In a Dynamic Positioning (DP) vessel such as a Platform Supply Vessel (PSV), the diesel engines sometimes work at the partial load condition. The efficiency of...

In this project we introduce the sintering process, which involves two basic phenomena, pore shrinkage and grain growth, occurring simultaneously. The objective of this project is to quantitatively describe the sintering process incorporating the kinetics of pore shrinkage and grain growth. First we build a model for pore shrinkage separately....

Mathematical modeling tools are useful for predicting the safe operation limits and efficiencies of SOFCs. For a particular SOFC design, variations in internal methane reforming kinetic parameters is expected to affect local gas compositions, local Nernst voltages, current densities and temperature profiles and in turn the safe operation limits...

In the current situation, although there are advantages of intermodal freight transport, the performance of intermodal freight transport (IFT) is not good. The market share of IFT is low compared with single-mode road transport. It is necessary to analyze the current operation of IFT system and apply the concept of synchromodal transport to...

Some polymers are not only transparent and lightweight, but also impact and ballistic resistant. Designing and preparing such polymeric materials with a high impact?resistant performance is of importance to e.g. aviation, military and windscreen applications.
