Abstract

SARI
Cekungan Sumatra Tengah dikenal sebagai cekungan matang dan memiliki
potensi hidrokarbon yang sangat baik. Cekungan Sumatra Tengah merupakan salah
satu cekungan penyumbang migas terbesar bagi Indonesia. Cekungan Sumatra
Tengah tersusun atas beberapa formasi, salah satunya Formasi Upper Red Bed dan
Formasi Brown Shale yang memiliki karakteristik reservoir yang beragam. Metode
yang digunakan dalam penelitian adalah metode deskriptif analitik yang terdiri dari
interpretasi litologi menggunakan metode penentuan cut-off dan analisis fasies
menggunakan metode elektrofasies. Berdasarkan analisis data didapatkan litologi
berupa batupasir masif berukuran sangat halus – kasar dan shale berwarna coklat.
Asosiasi fasies penyusun tiap sumur penelitian adalah braided stream, overbank
dan floodplain, channel, crevasse splay, fan delta, prodelta, shallow lacustrine dan
deep lacustrine dengan lingkungan pengendapan Fluvial-Lacustrine. Berdasarkan
hasil analisis kontrol fasies terhadap karakteristik reservoir, fasies braided stream
dan channel termasuk dalam pengontrol yang sangat baik untuk karakteristik
reservoir, pada fasies fan delta termasuk dalam pengontrol cukup baik untuk
karakteristik reservoir, dan pada fasies shallow lacustrine termasuk dalam
pengontrol buruk untuk karakteristik reservoir.

ABSTRACT
The Central Sumatra Basin is known as a mature basin and has excellent
hydrocarbon potential. The Central Sumatra Basin is one of the largest oil and gas
contributing basins for Indonesia. The Central Sumatra Basin is composed of
several formations, one of which is the Upper Red Bed Formation and the Brown
Shale Formation which have diverse reservoir characteristics. The method used in
the research is analytical descriptive method consisting of lithology interpretation
using cut-off determination method and facies analysis using electrofacies method.
Based on data analysis, the lithology is obtained in the form of massive sandstones
of very fine - coarse size and brown shale. The facies association of each research
well is braided stream, overbank and floodplain, channel, crevasse splay, fan delta,
prodelta, shallow lacustrine and deep lacustrine with Fluvial-Lacustrine
depositional environment. Based on the results of the facies control analysis of
reservoir characteristics, braided stream and channel facies are excellent
controllers of reservoir characteristics, fan delta facies are fair controllers of
reservoir characteristics, and shallow lacustrine facies are poor controllers of
reservoir characteristics.
