Abstract

The carbonate reservoir is one of the reservoir characters found in hydrocarbon fields in Indonesia. Carbonate reservoirs have complex porosity and permeability relationships. So it is necessary to do a special reservoir character that is different from the siliciclastic reservoir. Efforts that can be made to assist the development of this hydrocarbon field are to analyze the reservoir character in more detail using the petrophysical rock type (PRT) approach. This approach is used by combining geological elements such as the depositional environment, the petrophysical properties of the rock, as well as the fluid flow in it which is reflected by capillary pressure and water saturation. Modeling with this method is expected to be a method that can increase hydrocarbon production optimally in Xena Field. The object of research from Xena Field is Zone A2 which is included in the Parigi Formation. The Parigi Formation is one of the main hydrocarbon-producing reservoirs. The data used in this study are routine core analysis (RCAL) rock data on JLB-07, JLB-08, JLB-02, JLB-23 wells, wire log data (gamma-ray log, resistivity log, density log, neutron log) of 30 wells, and 2D seismic data. The depositional facies are divided into 2 facies, namely the margin reef platform facies and the interior platform facies. Identification of rock type (RT) using the flow zone indicator (FZI) method. The rock type in this field can be divided into 4 rock types, namely RT 1, RT 2, RT 3, RT 4 with RT 1 being able to drain the best fluid and RT 4 to drain the worst fluid. Reservoir property modeling is controlled by facies and rock type (RT) models. The margin reef platform facies are associated with RT 1 and RT 2. The interior platform facies are associated with RT 2 and RT 3.

Abstract

Desa Jugosari, Kecamatan Candipuro, Kabupaten Lumajang, Jawa Timur, merupakan daerah yang banyak dipengaruhi aktivitas vulkanik. Material yang terdapat di daerah telitian merupakan transportasi dari material hasil aktivitas gunungapi Semeru, yang terbawa oleh aliran sungai dan mengendap sebagai aliran lahar di sekitar sungai daerah penelitian. Perencanaan kegiatan pascatambang dilakukan untuk meminimalkan kerusakan lingkungan yang terjadi pasca kegiatan penambangan, dan mengembalikan peruntukan lahan seperti sedia kala. Beberapa aktivitas reklamasi pada lahan bekas tambang antara lain: pembongkaran, reklamasi lahan fasilitas tambang, reklamasi lahan bekas tambang, penanganan pengurangan karyawan (PHK), pengembangan usaha masyarakat lokal, pemeliharaan dan pemantauan, dengan jumlah biaya pasca tambang yang dijaminkan berdasarkan perhitungan harga saat ini adalah sebesar Rp.22.000.000,-.

Abstract

Nannoplankton merupakan organisme yang bersifat vagile, uniseluler dan mempunyai dua flagel. Spesies ini hidup dalam lingkungan air hangat dengan iklim tropis. Daerah penelitian berada pada Formasi Sonde yang litologi penyusunnya secara umum dari sedimen batugamping dan batulempung. Penelitian ini dilakukan untuk mengetahui kelimpahan dan keragaman nannoplankton pada lintasan Kali Soko dan sekitarnya.
