Abstract

Geothermal systems as the renewable energy can be indicated by the presence of surface manifestations, such as hot spring water in the Kedungoleng village, Paguyangan Brebes. The hot spring water temperature reaches 740 C is the outflow zone of Mount Slamet geothermal system. Resitivity method is one of the geophysical methods to study subsurface structures based on the electrical properties of rocks. The purpose of this study is to identify the subsurface geological structure in the area of geothermal manifestations Paguyangan based on resistivity method using Schlumberger configuration. Data acquisition process was performed by 5 sounding points with a length of 400 metre for each points. The field data consist of current, voltage and apparent resisitvity were processed using inversion method from IPI2Win software to determine the true resistivity values. Rock lithology and geological structure were analyzed by correlating resistivity and local geological information.The lithology of research area are topsoil with the resistivity is 9,91 to 114 ohm-metre then Sandstones with the resistivity is 0,756 to 6,91 ohm-metre. The next is Shale with the resistivity is 45,1 to 107 ohm-metre and Marl is 31 to 92,3 ohm-metre. The hot spring water is controlled by fault structure which a detected depht approximately 130 metre. Moreover, the Sandstone roles as permeable layer which contains the thermal fluid.Keywords: Fault, geothermal, lithology, Paguyangan, resistivity, and Schlumberger

Abstract

Gravity data inversion requires a good initial mesh model to generate a good subsurface model. Ambiguities in gravity data can be reduced by Euler deconvolution’s point cluster result that show its position and depth. These point cluster can give an additional information to shape the initial mesh model for inversion. The purpose of the study was to determine the influence of Euler deconvolution to the inversion. Inversion was done by the steepest descent algorithm. Euler deconvolution method and inversion algorithm were tested on synthetic models and showed good results that Euler deconvolution able to construct actual density distribution. These methods were applied to the gravity data on the "B24” geothermal field. Residual anomaly map has a value of -12 to 24 mGal. The geothermal field is estimated that it has a major fault which mainly striking in northwest-southeast direction. These estimates are supported by the results of Euler deconvolution which indicate the presence of fault and graben structure. Euler deconvolution and inversion method were applied perpendicularly to the main structure at the southwest-northeast direction. The results of this study are the Euler deconvolution method is able to provide information for a mesh geometry for inversion. From the inversion result, “B24” geothermal field is estimated has a high-low-high density distribution dominated by andesite and tuff. To improve the results of the research, it needs a measurement point addition, additional modeling area, geological and geochemical data to strengthen the interpretation.Keywords: density, Euler deconvolution, gravity inversion, geothermal

Abstract

This research used secondary data configuration Schlumberger geoelectric method in the area of geothermal manifestations Kaliulo Mount Ungaran to implement the use of artificial neural network algorithm in geophysical this case to obtain the actual value of the thickness and resistivity. In this artificial neural networks do two processes, namely the training and testing, the training using synthetic data and on testing using field data Then in training the neural network produced the best architectural which is used train resilient propagation (train rp) with three hidden layers with each neuron in the hidden layer consist of 300 neuron, this architecture will be used in testing. The output of the test data is value of the thickness and true resistivity which can be modeled. Result modeling of data processing from ANN is almost the same with IPI2WIN, MSE value obtained is equal to 0.10519 and 0.088304 respectively on the thickness and resistivity actually. The result of 3D model shows the lower part of the earth's subsurface its rock consists as following: topsoil, clay, volcanic breccias, tuff and limestone.

Abstract

Multiple caused by waves that trapped in a layer of sea water or rock layers. The effect information propagation time longer effect as if there is a new layer, thus looping wave reflection. The existence of multiple noise is disruptive and even damaging that complicates intrepetasi in interpreting seismik that have focused so that multiple seismik cross sections obtained free of multiple. Methods in multiple energi weaken, one of them by using the filtering radon method which, in principle, filtering radon, radon transform of the data pre-stack time-offset domain (t-x) in the domain of p-tau (τ-p). In τ-p domain and the expected multiple primary signal can be distinguished by the speed difference moveoutnya. This study aims to evaluate the response of radon filtering is applied to the conventional method for multiple mengatenuasi. The results obtained from the radon showed multiple filtering methods reduced from previous conventional methods which showed multiple. It shows good effect radon filtering methods to weaken multiple.Keywords: multiple, Radon filtering, conventional method.

Processing data by analysis gradient horizontal has been done to determine the structure of fault. From the map complete Bouguer anomali (ABL) shows anomalies in the middle of the study area which is a crater form of Mount Poco Ranakah, Poco Manggung, Poco Mandasawu and Poco Kasteno. In the southwest of the study area there is a low anomaly associated with alteration zone of rocks and hot springs. The high anomaly to the North of the study area lies in the crumpled hills, so that the area is dominated by high anomaly values. Gradient analysis were performed determine the limits of lithogy and the structure of fault associated with the appearance of hot springs and fumarol or sulfate in the study area.

Abstract

Extended Elastic Impedance (EEI) inversion method has been used to analyze sandstone lithology distribution of Talang Akar Formation in Cilamaya Field, North West Java Basin. The target zone was Z2230 layer which located in Talang Akar Formation with litologies of sandstone and shale. Sensitivity analysis showed that gamma-ray and density are sensitive to discriminate the type of lithologies in Z2230 target layer. EEI(58) could simulate gamma-ray and EEI(12) could simulate density with respectively 0,397 and 0,613 correlation values. EEI(12) inversion result showed sandstone lithology distribution in Z2230 layer with 8800 to 9800 . Sandstone lithology distribution concentrated in northwest–southeast of study area. There was hydrocarbon prospect area in north of well OTR-10.Keywords : Extended Elastic Impedance (EEI), gamma-ray, density, sandstone
