Abstract
Lapangan Melayu terletak di Cekungan Sumatera Tengah, merupakan
salah satu lapangan penghasil minyak yang di operasikan oleh PT. Chevron Pacific
Indonesia. Lapangan Melayu terletak sekitar 70 km ke arah barat laut dari Kota
Pekanbaru, ibukota Provinsi Riau.
Berdasarkan hasil interpretasi lingkungan pengendapan didapatkan bahwa
Kelompok Sihapas merupakan tide dominated delta dengan fasies pengendapan antara lain
channel, tidal channel,tidal mud flat, tidal ridge, delta front, dan prodelta. Dari interpretasi
korelasi sikuen stratigrafi didapatkan 4 sikuen. Hasil interpretasi system tract didapatkan
berdasarkan ciri fasies pengendapan, log pattern dan biostratigrafi. Dimana berdasarkan
umur yang terdapat pada data biostratigrafi, maka orde penelitian berada pada orde 3 yang
dipengaruhi oleh eustasy (perubahan muka air laut).
Model paleogeografi dibuat berdasarkan pembagian system tract dalam
bentuk 2 dimensi dan 3 dimensi sehingga didapatkan LST 1 (Channel), TST 1 (pro
delta delta front, dan tidal ridge). HST 1 (delta front dan pro delta). LST 2 (tidal channel).
TST 2 (delta front dan pro delta). HST 2 (delta front). LST 3 (tidal ridge). TST 3 (delta
front dan pro delta). HST 3 (delta front). LST 4 (tidal ridge). TST 4 (delta front dan
prodelta)

The located of Melayu Field in Central Sumatera Basin, one of the prospect oil field
that operated by PT. Chevron Pacific Indonesia. The located of Melayu Field about 70 km to
Northwest from Pekanbaru, capital city of Riau province.
Based on the interpretation results of depositional environmental that Sihapas
Group is tide dominated delta with environmental facies channel, tidal channel,tidal mud
flat, tidal ridge, delta front, dan prodelta. Sequence stratigraphy correlation found four
sequence. The interpretation results of system tract found based on characteristic of
environmental facies, log pattern and biostratigraphy. Where by age contained in the data
biostratigraphy, then order the research is on the order of three who is affected by eustasy
(changes in sea level).
Paleogeography models made based on classification of system tract in form
2 dimensional and 3 dimensional and produced LST 1 (Channel), TST 1 (pro delta delta
front, dan tidal ridge). HST 1 (delta front dan pro delta). LST 2 (tidal channel). TST 2 (delta
front dan pro delta). HST 2 (delta front). LST 3 (tidal ridge). TST 3 (delta front dan pro
delta). HST 3 (delta front). LST 4 (tidal ridge). TST 4 (delta front and prodelta).
Keyword : Melayu Field, Tide Dominated Delta, Sequence Stratigraphy, paleogeography.
