Fast imaging techniques of marine controlled source electromagnetic (CSEM) data
… structure of the subsurface<br/>from marine CSEM data involves complex processes. 1D and 2D forward and inverse<br/>modelling are currently the standard approaches used to produce geoelectrical models,<br/>with 3D inversion fast becoming a realizable method. However, these methods …

Inversion Analysis of Time-Domain Controlled-Source Electromagnetic Data to Characterize Offshore Freshened Groundwater in the Canterbury Bight, New Zealand, and Offshore Maltese Islands
… Marine controlled-source electromagnetic (CSEM) methods are effective in delineating the spatial extent of OFG bodies by using electrical resistivity as a proxy. Integrating resistivity models with subsurface properties, such as host-rock porosity derived from in situ measurements or …

Joint Elastic-Electrical Properties of Reservoir Sandstones
… marine controlled source electromagnetic (CSEM), sub-seabed imaging has developed to a state where routine resistivity mapping of hydrocarbon reservoirs is now possible. Co-located marine seismic and electrical resistivity survey data could provide the engineering parameters needed to …

Seismic-Style Processing of Numerical Em Data
… several variations of a standard 1-D numerical CSEM model, calculated using seismic-style acquisition parameters: an impulsive source and many receivers, unaliased. The data are normalized to unit maximum amplitude at each offset, making the weak far-offset signal visible (seismic-style) without …

Computational Investigations of Boundary Condition Effects on Simulations of Thermoacoustic Instabilities
… of the Continuous Sensitivity Equation Method (CSEM) applied to the Computational Fluid Dynamics (CFD) simulation of thermoacoustic instability problems. The proposed sensitivity analysis approach only requires a single run of the CFD simulation. Moreover, the sensitivities of field variables, …

Assessing low thermal conductivity of bricks which contain rice husk, corn cob and waste tea as an additive material
… mm x 65 mm. Compressed Stabilized Earth Machine (CSEM) with 900-1000 psi pressure was used in producing these bricks. This study focused on the compressive strength, water absorption and thermal conductivity of the fired clay bricks according to the BS 3921: 1985, MS 76: 1972 and ASTM C518 …
