dc.description.abstract | Eskplorasi bawah laut berkaitan dengan penggambaran struktur bawah laut
yang dapat dilakukan dengan metode Seismik. Metode seismik refleksi merupakan
salah satu metode yang dianggap paling baik dalam struktur tersebut. Akuisisi data
seismik di lapangan masih mengandung banyak noise, yaitu data yang tidak
diharapkan dan bersumber dari instrumen, proses perambatan gelombang maupun
dari lingkungan yang dapat mengganggu hasil penampang seismik menjadi tidak
jelas. Dalam pengolahan data seismik terdapat beberapa metode untuk mendeteksi
dan mengatenuasi multiple jenis long-period multiple. Beberapa metode tersebut
diantaranya adalah metode F-K Filter dan metode Surface Related Multiple
Elimination (SRME). Penelitian ini bertujuan mengevaluasi penggunaan metode F K Filter dan Surface Related Multiple Elimination (SRME) dalam mendeteksi dan
mengatenuasi noise jenis long-period multiple pada data seismik multichannel 2D
di Perairan Morowali, Sulawesi. Metode F-K Filter bisa mengatenuasi noise yang
terekam, termasuk multiple dan menyebabkan sinyal penampang seismik terlihat
lebih jelas. Perlu diterapkan metode SRME untuk mengatenuasi multiple jenis long period multiple. Metode SRME berhasil mengatenuasi multiple jenis long-period
multiple yang terdapat pada zona near offset dan juga berhasil mempertahankan
sebagian besar reflektor utama. | id |
dc.description.abstract | Underwater exploration is closely related to the depiction of underwater
structures can be carried out using the seismic method. The seismic reflection
method is one of the methods that is considered to be the best in delineating under
water structures. Field seismic data acquisition contains a lot of noise, namely
unexpected data originating from instruments, wave propagation or from
environment that can lead results of the seismic cross-section being unclear. In
seismic data processing, there are several methods to detect and attenuate multiple
types of long-period multiples. Some of these methods include the F-K Filter and
the Surface Related Multiple Elimination (SRME) methods. This study aims to
evaluate the F-K Filter and Surface Related Multiple Elimination (SRME) methods
in detecting and attenuating long-period multiple noise in 2D multichannel seismic
data from Morowali Waters, Sulawesi. The F-K Filter method can attenuate the
recorded noise, including multiples and cause the seismic cross-sectional signal to
be seen more clearly. The SRME method succeeded in attenuating multiple types
of long-period multiples in the near offset zone and also managed to maintain most
of the primary reflectors. | id |
