Abstract

The necessary of technology at this time resulted the necessary of energy resources will increasing, and it also result the scarcity of energy resources. One of the energy resources that is still used as a major energy resource is oil and gas. To overcome these problems, exploration activities at this time needs to be further improved. In the field of exploration, one of the most important things to know is reservoir. Reservoir quality is important for us to know so that we can determine whether an area has hydrocarbon potential to be developed or not. The main parameters of reservoir quality are porosity and permeability.In this study discussed the analysis of provenance, diagenetic and depositional environment of the sandstone reservoir of Talang Akar Formation, North West Java Basin and from the results of the analysis will be associated with the effect on reservoir quality. To determine the reservoir quality based on these parameters, can be done by several methods such as petrographic, cores, SEM and XRD analysis. From the analysis that has been done can be seen that the provenance of Talang Akar sandstone is Granite. So it can be seen that the Talang Akar sandstone which the provenance is Granite has good reservoir quality, with porosity values ranging from 19.04% to 24.28% and permeability ranging between 30-674 mD or belonging to the class good - very good (Koesoemadinata, 1980). Then the diagenetic process that occurs is compaction, cementation, replacement and dissolution. The process of compaction, cementation and replacement leads to reduced rock porosity values ranging from 2.25 to 11.5%, while the dissolution process resulting in increased rock porosity is about 1.5 - 2%. The depositional environment of the Talang Akar Sandstone is Upper Delta front. Rock facies in the upper delta front has good reservoir quality, with porosity values range from 19.04% to 24.28% and permeability range between 30-674 mD or belonging to the class is good - very good (Koesoemadinata, 1980).

Abstract

Asam-asam Basin is one of the basins where to be found good quality coals in Kalimantan, especially in the the Eocene Tanjung Formation. The studies of Tanjung Formation have been done by other researchers, but study devoted to the Tanjung Formation of Asam-asam Basin has not been done yet. The purpose of this study was to determine the lithological characteristics found in the study sites, geological structure, sedimentary rock facies, as well as studies about the relationship between sedimentary rock facies with quality parameters of coal based on laboratory proximate test analysis. The study was conducted using descriptive methods include case study research and direct observation in the field through geological mapping and stratigraphic measurements, as well as analysis method include performed data processing as a result of field observation and other supporting data. The processed data is presented in the form of lithology columns, maps, and data of geological structure. After that performed the laboratory analysis includes analysis of sedimentary facies and structural analysis of geology. In the final stage is the interpretation of sedimentary facies and their relationship with quality parameters of coal based on proximate test analysis. Based on the results of research, it is known that geological structures that develop in area of research are systematical joints with main force direction North-Northeast (NNE) - South-Southwest (SSW), normal faults with a trending fault plane Southwest - Northeast , as well as the reverse fault with a trending fault plane Northwest - Southeast. From the facies analysis, rocks of older age at study sites are sedimented on transitional lower delta plain environment, with sub-environment includes swamp, interdistributary bay, distributary channels, and crevasse splay; whereas the younger rocks are sedimented in the lower delta plain environment, with sub-environment includes swamp, interdistributary bay, distributary channel, crevasse splay, and tidal flats. There are 11 coal seams exposed as the results of the field observations, from the oldest to the youngest age are seam L2, L1, L30, M25, M50, and M30 whose are sedimented in the transitional lower delta plain environment, also seam R1, R15, R2, R 3-1 and R 3-2 whose are sedimented in the lower delta plain environment. Based on the proximate analysis test, it is known that : ash values ranged 7-50%, classified as moderate to high (Graese, 1992); sulfur total values ranged from 0.34 to 1.06%, classified as moderate to high category (Hunt, 1984); and calorific value ranges from 2836 - 6693 kcal/kg, and the relatively low quality coal to high quality (Directorat General of Mineral and Coal, 2011; within Indonesian Coal Resources Development and Future Direction Of Coal Export). Based on the value of ash (ash content), total sulfur, and calorific value, it is known that in general, the coal seams whose sedimented at the transitional lower delta plain environment have better quality than the coal seams of lower delta plain environment.

Abstract

Salah satu permasalahan yang sering terjadi di kecamatan Kramat, Suradadi, dan Warureja, Kabupaten Tegal adalah sulitnya masyarakat mendapatkan air bersih untuk kebutuhan industri maupun kebutuhan sehari-hari. Kesulitan tersebut disebabkan karena belum adanya data pendukung untuk dilakukannya pengeboran airtanah sehingga tentunya masyarakat merugi bila hasil pengeboran airtanah mereka belum kunjung menemukan sumber air bersih. Tujuan dari penelitian adalah menentukan zona akuifer, jenis akuifer dan arah aliran airtanah berdasarkan pemetaan hidrogeologi dan pengolahan data geolistrik metode Schlumberger.Geolistrik merupakan metode geofisika yang digunakan untuk mengetahui kondisi geologi bawah permukaan berdasarkan variasi nilai resistivitas  jenis batuannya. Metode yang digunakan pada penelitian ini adalah geolistrik metode Schlumberger, dengan 16 titik pengukuran geolistrik yang tersebar di sekitar pantai utara Kabupaten Tegal. Proses pengolahan data dilakukan menggunakan software IPI2win untuk mengetahui nilai resistivitas sebenarnya beserta kedalamannya.Hasil interpretasi litologi berdasarkan nilai resistivitas batuan, dapat dikelompokkan menjadi lempung air Asin (0,06-0,27 Ωm), lempung air Payau (0,4-0,99 Ωm), lempung air tawar (1,057-9,714 Ωm), lempung pasiran (10,18-19,87 Ωm), pasir (20,44-119,7 Ωm) dan gravel (≥ 124,3 Ωm). Litologi akuifer pada daerah penelitian berupa pasir yang memiliki sifat permeabilitas dan porositas yang baik. Hasil dari nilai resistivitas dibuat penampang geolistrik dan dikorelasikan untuk menentukan letak, dimensi dan jenis akuifer  yang terdapat pada daerah penelitian. Jenis akuifer yang terlihat dari hasil korelasi adalah akuifer bebas, akuifer bocor dan akuifer tertekan. Debit aliran airtanah pada akuifer tertekan pada wilayah penelitian ini adalah 4090,82 m3/hari. Nilai tersebut setara dengan 47,35 liter/detik atau setara dengan 1.493.149,3 m3/tahun.
