Abstract

Geothermal features can be observed in areas of active volcanism, or areas that have inactive volcanoes. In non-volcanic areas, the temperature of rocks within the Earth also increases with depth. This temperature increase is known as the Geothermal Gradient. If water percolates deeply enough into the crust, it comes into contact with hot rocks and can circulate to the surface to form hot springs. The collection of field hydrothermal data during field study with the help of portable instruments. The different physical parameters of the thermal springs such as temperature, pH, colour, and odour of thermal fluid are noted. The temperature of the thermal springs ranges from 43oC to 48oC. The pH value of the thermal waters shows a neutral (pH 6-6.6) and sulphur odour is discernible particularly. Based on geological, the system geothermal energy that develops is geopressured.

Abstract

Daerah panas bumi Waesekat termasuk dalam wilayah Kecamatan Kepala Madan, Kabupaten Buru Selatan, Propinsi Maluku. Jenis manifestasi berupa mata air panas bertemperatur sekitar 90°C dan batuan malihan. Morfologi sekitar manifestasi berupa satuan morfologi perbukitan dengan ketinggian 300–1500 mdpl. Identifikasi struktur bawah permukaan menggunakan metrode gravitasi / gaya berat. Metode gravitasi adalah salah satu metode geofisika yang digunakan untuk mengukur variasi percepatan gravitasi bumi akibat perbedaan rapat massa antar batuan.Dari data yang diperoleh di sekitar Waesekat terdapat anomali tinggi di sebelah Barat Daya daerah penelitian, dan rendah di sebelah Timur Laut. Potensi panas bumi diduga berada di daeah Timur Laut yang nilai anomalinya rendah. Berdasarkan korelasi dengan data geologi, struktur bawah permukaan, daerah ini tersusun atas serpih, batu pasir dan batu gamping.

Abstract

Laboratory analysis has proven the Talang Akar Formation as a source rock that is relatively rich in organic content, but the availability of laboratory data is very limited to determine the quantity of organic material in a regional basin area, which is the main objective in this research. Therefore, a simple proven and accurate method is needed to model the TOC (organic carbon content) throughout the borehole is needed. TOC log modeling was performed using the Passey method, multilinear regression and neural network. Based on the modeling results, the multilinear regression method got better results to be applied to the Talang Akar Formation.

Abstract

Metode waktu tunda plus minus adalah metode perkiraan tetapi jauh lebih cepat dan akurat. Tujuan dari penelitian ini adalah untuk menentukan nilai kecepatan antar lapisan untuk menggambarkan model lapisan bawah permukaan dan mengidentifikasi jenis batuan pada setiap lapisan menggunakan metode waktu tunda plus minus. Hasil dari pengolahan data menggunakan metode waktu tunda plus minus diperoleh dua lapisan, yaitu kecepatan gelombang seismik lapisan pertama adalah 4107,4 m/s dan lapisan kedua adalah 4715,9 m/s. Dari model lapisan bawah permukaan dapat diartikan bahwa lapisan pertama adalah Batugamping dengan kadar air 17% dan lapisan kedua adalah Batugamping dengan kadar air 20%.

Abstract

Multiple in marine seismic data is the noise formed due to the high impedance contrast at the boundary between layer. Multiple interferes the data processing that will also affect the interpretation of subsurface image. The use of seismic reflection in ocean has become an activity that is often performed with a variety of purposes, to map the subsurface. The basic objective of seismic data processing is to convert the recorded information from the field into data that can be interpreted. One goal of seismic data processing is to eliminate or reduce the noise of reverberation and multiples as well as enhance the signal to noise ratio. The data are a 2D marine reflection seismic data with SEG-Y format that will be processed with using ProMAX software. SEG-Y data are combined with field geometry data in processing of header load, then is carried out noise reduction (trace editing and filtering), and seismic signal amplification (deconvolution and TAR).

Abstract

Characterization of the depositional environment is carried out by means of facies modeling analysis based on electrofacies which can provide rapid information about the depositional system of a rock formation. The purpose of this research is to interpret the determination of the depositional environment in the research area for the further development of exploration / exploitation of hydrocarbons. Methodology applied is gamma ray log interpretation (log GR) using the relative correlation between log shape variations and sedimentation facies. The approach in this study uses the interpretation of the log response pattern results including Serrated, Blocky, and Bell. Based on log interpretation, study area was deposited on transitional lower delta plain zone.

Abstract

Manifestasi panas bumi berupa mata air panas Reatoa Desa Samaenre, Kecamatan Mallawa, Kabupaten Maros sangat menarik untuk dikaji. Tujuan penelitian ini untuk mengetahui karakteristik geokimia air panas dan pendugaan temperatur bawah permukaan. Metode yang digunakan dalam penelitian tersebut meliputi studi lapangan, pengambilan sampel air, analisis laboratorium dan interpretasi menggunakan diagram trilinier HCO3- – Cl-– SO42-, diagram trilinier Na – K – Mg, dan diagram trilinier Cl – F – B. Tipe fluida pada daerah tersebut tergolong sebagai bikarbonat (dilute-chloride). Tipe fluida ini terbentuk dari pengenceran air klorida oleh air bikarbonat selama pergerakan lateral. Analisis rasio unsur kimia Na – K – Mg menunjukkan bahwa fluida tersebut termasuk dalam kategori air yang belum matang (immature water) yang telah bercampur dengan air dangkal yang memiliki konsentrasi silika rendah. Konsentrasi Cl yang dominan mengindikasikan bahwa fluida pada mata airpanas ini berasal dari reservoir dalam dan menandakan adanya zona permeabel. Suhu reservoir dengan metode geotermometer kimia Na/K diperkirakan sekitar 137–147 °C dan geotermometer K/Mg menunjukkan suhu berkisar antara 41.30 – 41.57 °C mengindikasikan suhu reservoir ini termasuk dari sistem reservoir bersuhu rendah.
