SARI
Formasi Parigi, Lapangan “AD” termasuk dalam Cekungan Jawa Barat Utara,
dan merupakan formasi yang disusun oleh batuan karbonat serta salah satu reservoir
produktif di cekungan ini. Penelitian ini dilakukan dengan maksud dan tujuan untuk
mendapatkan gambaran variasi litologi, pola system tract, kerangka strartigrafi secara
lateral, persebaran fasies dan lingkungan pengendapan pada formasi Parigi yang buat
dalam satu bentuk laporan penelitian.
Metode yang digunakan dalam penelitian ini dengan analisis data sumur
pemboran meliputi data log sumur, trajectory, mudlog, dan core, menghasilkan
interpretasi litologi, litofasies, sikuen, dan lingkungan pengendapan.
Hasil analisis menunjukkan bahwa Formasi Parigi terdiri dari batugamping
dengan tiga litofasies: mudstone, wackstone, dan packstone. Elektrofasies
diinterpretasikan dalam tiga bentuk: funnel shaped, cylindrical, dan bell shaped.
Daerah penelitian diinterpretasikan memiliki satu sikuen yang meliputi sequence
boundary, transgressive surface, dan maximum flooding surface, dengan sistem tracts
yang terdiri dari High System Tract (HST), Lowstand System Tract (LST), dan
Transgressive System Tract (TST). Berdasarkan hasil analisis lebih lanjut, daerah
penelitian diendapkan pada lingkungan outer dan inner ramp.

ABSTRACT
The Parigi Formation, located in the "AD" Field within the North West Java
Basin, is a carbonate formation and one of the productive reservoirs in this basin. This
study aims to provide an overview of lithology variations, system tract patterns, lateral
stratigraphic framework, facies distribution, and depositional environments within the
Parigi Formation, presented in a research report.
The methods used in this study involve the analysis of drilling data, including
well logs, trajectory, mudlog, and core data, to interpret lithology, lithofacies,
sequences, and depositional environments.
Results of the analysis indicate that the Parigi Formation consists of limestone
with three lithofacies: mudstone, wackestone, and packstone. Electrofacies are
interpreted in three shapes: funnel-shaped, cylindrical, and bell-shaped. The study
area is interpreted to have one sequence comprising a sequence boundary,
transgressive surface, and maximum flooding surface, with system tracts consisting of
High System Tract (HST), Lowstand System Tract (LST), and Transgressive System
Tract (TST). Further analysis suggests that the study area was deposited in outer and
inner ramp environments.
