Cekungan Timor termasuk kedalam kategori semi mature yang memiliki potensi hidrokarbon, namun kompleksitas kondisi geologi dan banyaknya konsep yang berbeda-beda merupakan salah satu penyebab stratigrafi di cekungan ini sulit dimengerti. Penelitian stratigrafi rinci untuk mengidentifikasi fasies dan sub fasies lingkungan pada batuan berumur Perem-Trias dilakukan di daerah Kekneno, Nenas, Cekungan Timor untuk memberikan pandangan baru mengenai stratigrafi, sedimentologi dan fasies lingkungan pengendapan pada batuan berumur Perem-Trias di cekungan ini. Hasil analisis litofasies menunjukkan bahwa batuan yang berumur Perem di daerah Kekneno diendapkan pada fasies lereng bagian bawah sampai atas (lower to upper slope facies), sedangkan batuan berumur Trias umumnya diendapkan sebagai fasies sistem kipas luar (outer fan system facies), fasies paparan luar samping lereng atas (outer shelf to upper slope facies), fasies sistem kipas tengah (middle fan system facies), dan fasies sistem kipas dalam (inner fan system facies). Endapan-endapan alur (channel) dan pematang (levee) pada batuan berumur Trias berpotensi menjadi target play hidrokarbon.
Kata Kunci: fasies, kipas bawah laut, batuan Perem-Trias, Cekungan Timor
