Abstract
Telah dilakukan penelitian hasil pengolahan Post Stack Time Migration metode
FK pada lintasan “JMC 11” Cekungan Pati, Secara fisiografis, daerah penelitian
termasuk dari bagian paparan Laut Jawa, yang dan secara geografis termasuk
dalam wilayah perairan Kabupaten Jepara, Provinsi Jawa Tengah. Terletak pada
koordinat antara 111
o
06’ – 111
o
29’ BT dan 06
o
22’LS – 06
o
33’ LS dengan panjang
lintasan 35,20 km, dan Seismic Recording System dilakukan di kapal Geomarin
III, pengolahan data seismik 2D dengan menggunakan perangkat lunak Landmark
ProMax2D Linux (Promax 2D Version 2003.12.1 ). Dimana pengolahan data
seismik dilakukan dengan S/N (Signal To Noise Ratio) sebaik mungkin.
Penelitian ini bertujuan untuk mengidentifikasi gambaran struktur geologi bawah
permukaan guna mengetahui bidang batas lapisan, struktur patahan, dan
mengetahui konfigurasi refleksi dari interval batuan yang dibatasi, dimana
diperoleh dari data rekaman seismik yang direkam dipermukaan bumi.
Hasil yang diperoleh dari Identifikasi Struktur Geologi berdasarkan analisa
seismik 2D yang diinterpretasi dari penampang time migration terdapat 6 (enam)
satuan batuan (formasi) sebagai pembatas antar bidang lapisan, 7 (tujuh) bidang
patahan, dan Terdapat 3 (tiga) konfigurasi refleksi pada tubuh/interval batuan
yang dibatasi (Upper/Lower) oleh bidang perlapisan yaitu: KR 1, KR 2, KR 3.

Had been done research results of Post Stack Time Migration processing using FK
method on the line “JMC 11” Pati Basin, The Physiographic areas of research
included the exposure of the Java Sea, and is geographically included in the
teritorial waters Jepara Regency, Central Java Province. Located at coordinates
between 111

33’ LS with 35.20 km line
length , and Seismic Recording System carried on board Geomarine III, the
processing of 2D seismic data using Landmark software ProMax2D Linux
(Promax 2D Version 1.12.2003). Where seismic data processing is done by S/N
(Signal To Noise Ratio) as possible.
This research aims to identify the picture of the subsurface geological structure in
order to determine the boundary layer, structural faulting and know the
configuration of reflection of the rock bounded interval which is obtained from the
recorded seismic data recording surface of the earth.
The results obtained from the Identification of the structure geology based on
seismic 2D analysis of the cross-section of time migration interpreted there are
six (6) lithologies (formations) as a barrier between the boundary layer, seven (7)
fault boundary, and There are three (3) configurations reflection on the body/rock
interval bounded (Upper/Lower) by boundary layers that is: KR 1, KR 2, KR 3.
