Özet
The demand for
geothermal energy is increasing due to its clean, sustainable use as a
renewable resource. Geothermal energy may be used in many ways, such as in hot springs and spas, geothermal power
plants, fishing and farming industry, and heating individual buildings and as
well as the entire district. Geothermal energy is the accumulation of heat
energy as hot water within hot and dry rocks, steam or gases under pressure
within the earth's crust at various depths. The change in physical properties of
rock with temperature may be determined using electrical, electromagnetic,
gravity, magnetic, seismic, radiometric, well-logging and down hole geophysical
methods. The Caferbeyli geothermal system is situated within the confines of
the county of Manisa about 100
km east of İzmir. Increasing demand on thermal water requires
exploring new fields. For this purpose, geophysical studies may assist in
quantifying the geothermal energy potential of the area by delineating
subsurface fractures. The major purpose of this magnetic survey is to locate the
boudaries of active hydrothermal system in the South of Gediz Graben in Caferbeyli.
The presence of the hydrothermal system had already been inferred from surface
evidence of hydrothermal
activity and drillings. Firstly, 3-D prismatic models were theoretically
investigated and edge detection methods were utilized to define the boundaries and the parameters of the
structure. In the
first step of the application, it was necessary to convert the total field
anomaly into a reduced-to-pole anomaly map. Then the geometric boudaries of the structures were
determined by applying a MATLAB based software with 3 different edge detection algorithms, such as tilt angle,
theta map and analytic signal methods. The exact location of the structures
were obtained by using
these boundary coordinates as initial geometric parameters in the
inversion process. In addition to these methods, reduction to pole and horizontal gradient
methods were applied to the data to achieve more information about the location and shape of
the possible reservoir. As a result, the edge detection methods were found to
be successful, both in
the field and as theoretical data sets for delineating the boundaries of the
possible geothermal reservoir structure. The depth of the geothermal reservoir was determined as 2,4
km from 3-D inversion and 2,32 km from radial amplitude power spectrum
methods.
