Abstract

Research has been carried out in Loli Village, Donggala Regency, Central Sulawesi using the Wenner-Schlumberger resistivity geoelectric method to determine the resource of andesite rocks. This measurement was done by determining the path points in the field using the Global Positioning System (GPS). The data collection was carried out using the geoelectrical resistivity method based on the area’s measurement plan. The data obtained was in the form of position data for each electrode, potential data (V), and current strength data (I) used to calculate the resistivity value (r). The results obtained from this research are andesite rock resource content, which was characterized by a high resistivity value ranging from 300–600 Wm. The resistivity value of the cover layer is low, ranging from 14–45 Wm. The latent content of andesite rocks was dominated in the southeast region on the trajectory of DRSA_01, DRSA_02, DRSA_03, DRSA_04, and DRSA_06 which had a lower topography than the northwest region. DOI: http://dx.doi.org/10.17977/um024v4i22019p045

Abstract

The pattern of surface currents and salinity distribution at the mouth of the Palu River by using the 2D coherens model to show that the presence of wind factors influences the velocity and direction of the tidal and non-tidal surface flow patterns at the mouth of the Palu River. Using primary and secondary data, the results show that non-tidal currents are more dominant with the direction of spread from the North to the East to the West then turn to the South, with a velocity of 2.57 m/s. The pattern of salinity distribution with tidal and non-tidal flow generators has a different model. Still, it has the same direction, namely the flow from North East to West direction, which is deflected to the South adjacent to the mouth of the Palu River estuary.

Abstract

The research that refers to the characterization of carbonate reservoir to identify lithology and fluid had been done to the Baturaja Formation in South Sumatera Basin. The method used is analyzed of Amplitude Versus Offset (AVO) by utilizing the petrophysics parameter of Lambda Mu Rho (LMR) and Extended Elastic Impedance (EEI). The goal of the research is to find out the comparison of the application of petrophysics parameter LMR and EEI to characterization carbonate reservoir, besides finding a prospect location or proposed well. The result of data analysis of Al-Fatah well shows that the carbonate reservoir position with liquefied gas is located deeper around 350 meters with a thickness of around 7.62 meters. Interpretation of seismic from inversion result by using the petrophysics parameter of LMR and EEI shows the presence of a prospect location to the CDP 4253 up to 4301, which is carbonate reservoir with fluid accumulation (gas).

Hasil dari penelitian ini menunjukkan bahwa penyusun tanah di daerah penelitian adalah kerikil, batu pasir, dan genes. Nilai hambatan jenis setiap lapisan batuan yaitu kerikil berkisar antara 10 Ωm – 84 Ωm, lapisan batu pasir berkisar antara 84 Ωm – 158 Ωm, dan lapisan genes berkisar antara 232 Ωm – 528 Ωm. Pada wilayah penelitian terdapat lapisan genes yang diduga merupakan bidang gelincir. Bentuk bidang gelincir yang diperoleh pada wilayah penelitian yaitu jenis gelincir rotasi dengan arah longsoran mengarah ke arah jalan raya dengan kedalaman 7 m – 35 m untuk semua lintasan. Investigation of the slip surface has been carried out in landslide-prone areas using the 2D resistivity geoelectric method on the Tawaeli-Toboli road using the Wenner configuration with 96 meters of track length, and 6 m of electrode spacing analyzed with Res2DinV software. Furthermore, the subsurface structure and lithology can be determined to provide information about the slip plane. This study's results indicate that the soil compilers in the study area are gravel, sandstone, and genes. The value of electrical resistivity of each rock layer, namely gravel ranges from 10 Ωm - 84 Ωm, sandstone layer covers from 84 Ωm - 158 Ωm, and the genes layer ranges from 232 Ωm - 528 Ωm. In the research area, there are layers of genes that are thought to be the slip plane. The shape of the sliding plane obtained in the study area is the rotating slip with landslide direction leading to the highway with a depth of 7 meter - 35 meter for all trajectories.

Abstract

Penelitian ini berupa analisis inversi data seismik dengan menggunakan impedansi elastik dan lr (lambda-rho) untuk mengestimasi kandungan  reservoir batupasir. Analisis Inversi Amplitude Versus Offset (AVO) dilakukan untuk mendapatkan reflektivitas impedansi elastik dan lambda-rho sehingga diperoleh kelas anomalinya. Dalam menentukan litologinya diperoleh sudut 30o sebagai sudut yang sensitif sehingga selanjutnya dilakukan proses inversi dengan sudut tersebut. Hasil dari analisis Anomali Inversi Amplitude Versus Offset (AVO) menetapkan kelas anomali respon terletak pada posisi IIp sehingga dengan menggunakan sudut 30o tersebut dilakukan pemetaan inversi impedansi elastik untuk mengetahui litologi batupasir yang diperkirakan mempunyai arah timurlaut-baratdaya. Selanjutnya untuk melakukan analisis untuk estimasi adanya fluida dengan menggunakan analisis inversi lambda-rho sehingga diperoleh nilai target 40-65 MPa*gr/cc pada litologi batupasir tersebut dengan arah orientasi utara-tenggara.

Abstract

Penentuan litologi dan kandungan hidrokarbon pada lapangan RST-3 dan RST-4 dilakukan dengan analisa kuantitatif dan kualitatif yang menggunakan parameter fisis batuan dan data log sumur. Tahap analisis dengan menggunakan kualitatif berupa data log gamma ray (GR), log spontaneus (SP), log resistivitas, log densitas (RHOB), log Neutron (NPHI) untuk mengetahui jenis litologi dan jenis fluida hidrokarbonnya. Pada tahap analisis menggunakan kuantitatif yang berupa perhitungan beberapa parameter fisis batuan antara lain porositas, saturasi, permebilitasnya. Hasil penelitian yang diperoleh dari analisis kualitatif dengan beberapa data log sumur bahwa daerah penelitian untuk sumur RST-3 dan RST-4 dimana untuk tiap sumur masing-masing mempunyai kandungan fluida hidrokarbon berupa minyak, gas dan air yang mana sumur RST-3 mempunyai 5 lapisan dan smur RST-4 mempunyai 6 lapisan. Untuk hasil menggunakan analisis kuantitatif dengan perhitungan beberapa parameter fisis batuan diperoleh pada lapangan memiliki pola lapisan litologi yang didominasi oleh limestone dan perselingan sandstone.

Abstract

Penelitian mengenai pola arus di Teluk Palu sangat jarang dilakukan, padahal perairan ini merupakan daerah potensi strategis secara ekonomi. Studi mengenai pola arus Teluk Palu dilakukan dengan memanfaatkan model Coherens menggunakan Bahasa pemrograman fortran dengan mengabaikan gaya pembangkit angin sebagai pembangkit arus. Hasil penelitian menunjukkan bahwa arus pada Teluk Palu bervariasi baik arah maupun kecepatannya. Besar kecepatan arusnya berkisar antara 0,01 m/s hingga 0,33 m/s. Kondisi ini sangat dipengaruhi oleh pergerakan pasang surut baik saat purnama maupun perbani. Model pola arus laut permukaan di Teluk Palu ini diharapkan dapat bermanfaat bagi pembangunan dan pengembangan sekitar area teluk, bagi masyarakat dan juga bermanfaat bagi penelitian-penelitian selanjutnya

Abstract

The need for oil and gas has led to increased exploration to produce hydrocarbons in various basins and discover new reserves. This was also done in the Kutai basin on the eastern island of Kalimantan using a quantitative correlation between geophysical logs and rock core data and qualitative analysis by analyzing geochemical data derived from the host rock. To determine the characteristics of the hydrocarbon source rock in the three test wells, three types were analyzed, namely organic material richness, organic material type, and maturity level. For the Maau-1, Wahau-1, and Tengkawang-1 test wells, the organic material content has an excellent type to become source rock. The three wells are of medium-special hydrocarbon potential in organic material, making them very likely to produce oil and gas. As for the nature of the material content, the three wells have a mature level of the source rock, making them very potential as the  very good source rock.

For the Maau-1, Wahau-1, and Tengkawang-1 test wells, the organic material content has an excellent type to become source rock. In terms of organic matter, all three wells have medium-special hydrocarbon potential and, therefore, high potential to produce oil and gas. As for the nature of the material content, the three wells have a mature level of the source rock, making them very potential as the very good source rock.
