A 3D finite-element modelling investigation into optimal survey parameters and direct imaging for marine controlled-source electromagnetic surveysLau, Ryan 17 September 2007 (has links)
Relatively little is known about marine controlled-source electromagnetic
surveys (MCSEM) used to detect hydrocarbon reservoirs. Typical MCSEM require the
use of inversion to generate a model of the subsurface. We utilize a 3D finite-element
forward model to simulate a MCSEM survey. With the results we were able to
determine the strengths and weaknesses of each transmitter and receiver configuration
that would best detect a shallow hydrocarbon target. Careful selection of the correct
configuration is important as we have found that incorrect transmitter orientation, offset
and receiver measurement component can yield misleading results. Using the ideal
configuration we were able to directly image the hydrocarbon target without the use of
inversion modeling. The direct image is able to show the hydrocarbon target's shape
and edges without any ambiguity. The direct image of the target can potentially be used
to refine 3D inversion modeling, or be used in conjunction with seismic profiles to refine
seismic picks.

The development and testing of a parametric sonar system for use in sediment classification and the detection of buried objectsLepper, Paul Andrew January 1999 (has links)
This thesis describes the work carried out in the development and testing of parametric sonar systems for application in the fields of seabed sediment characterisation and classification, and the detection of seabed embedded objects. Parametric sonar systems offer a number of advantages over conventional sonar systems. This is especially true of the conflicting requirements of both seabed delineation and penetration required for a practical sub-seabed profiling system. Echoes from sub-bottom layers vary in strength dependent on both the boundary acoustic reflectivity and the absorption characteristics of the layer above. Absorption effects are usually frequency dependent, allowing better penetration to lower frequency signals.

Seabed Filter Feasibility Study of Om Almisk IslandSesler, Kathryn 06 1900 (has links)
Freshwater access has always been and is continuing to be a severe problem in desert coastal regions, despite the fact that they have an unlimited supply of easily accessible saline water. Water desalination plants are well established and heavily relied upon throughout the Middle East, Saudi Arabia in particular. However, water desalination tends to be a very expensive and energy intensive solution to the problem. The transition from using open water intake systems and all of the pretreatment processes that they require, to using seabed water filters as an intake, would potentially reduce the lifetime costs, energy consumption, and environmental impacts commonly associated with water desalination. This is because the filtration process that the seabed filter generates, serves as sufficient pretreatment for seawater as well as eliminating any risk of entrainment or impingement of marine organisms. The main objective of this research is to conduct a feasibility study on Om Almisk Island, an island off the coast of King Abdullah University of Science and Technology (KAUST), to determine if it would be a suitable location to construct a seabed water filter as a replacement for the current open water intake. The Om Almisk Island site was evaluated through collection of sand samples over a radial grid around Om Almisk Island and sample analysis using grain size distribution, porosity, and hydraulic conductivity. The lack of mud, high hydraulic conductivity, proximity to KAUST, and the shallow waters of the sandy apron surrounding Om Almisk Island make this an ideal location for a seabed water filter to be used as an intake and pretreatment for the KAUST desalination plant. This location also has low tide change and the presence of benthic macrofauna to create bioturbation in the sediments, which could inhibit the growth of a schmutzdecke. If this biological layer forms, it could drastically reduce the hydraulic conductivity of the system. Due to the high hydraulic conductivity of the native sand, a relatively small footprint is possible for the design of the filter. A design with an intake of 105,000 m3/day, using four active galleries and one standby gallery was generated.
