Analisis tekanan pori dan gradien rekah adalah proses penting dalam pengeboran minyak dan gas untuk memprediksi tekanan yang terjadi di dalam sumur dan mencegah kejadian bencana pengeboran. Analisis ini berlokasi di lapangan RZZ sebagai salah satu lapangan produksi minyak dan gas alam pada Kalimantan Timur. Tujuan penelitian ini untuk mengetahui karakterisitik tekanan pori agar dapat menentukan metode yang tepat dalam optimasi berat lumpur pengeboran. Penelitian ini menggunakan data dari 14 sumur, berupa data log tali kawat, PTFA, LOT atau FIT, laporan pengeboran, mud log, interval velocity, dan Ro. Penelitian ini menggunakan metode Eaton (Eaton, 1975) pada analisis tekanan pori dan gradien rekah serta metode statistika pada optimasi berat lumpur. Hasil penelitian menunjukkan bahwa kedalaman top overpressure berada pada rentang 9,850 – 11,000 ftTVD pada Formasi Balikpapan dan top hard overpressure pada rentang 12,000 – 13,000 ftTVD pada Formasi Balikpapan juga. Hasil korelasi menunjukkan distribusi overpressure mengikuti struktur geologi yang berkembang yakni antiklin. Overpressure pada daerah penelitian disebabkan oleh mekanisme loading dan unloading. Mekanisme loading dibuktikan berdasarkan analisis sejarah pemendaman, sedangkan mekanisme unloading dibuktikan oleh plot silang Dutta (Dutta, 2002) dan nilai Ro. Optimasi berat lumpur pada section 12 ¼” dilakukan dengan cara menaikkan berat lumpur menjadi 2.65 ppg dari tekanan pori untuk menanggulangi permasalahan tight spot dan overpull. Sedangkan pada section 8 ½” dengan cara menurunkan berat lumpur menjadi 2.5-3.5 ppg dari tekanan pori untuk menanggulangi high gas. Penggunaan berat lumpur optimum ini akan meminimalisir terjadi permasalahan saat pengeboran sehingga pengeboran menjadi lebih efektif dan efisien.Kata Kunci: Tekanan Pori, Overpressure, Berat Lumpur, Mekanisme, Optimasi

Field X, as this study area's focus, boasts over 200 wells proven to be hydrocarbon producers. Two pore pressure regimes exist: normal hydrostatic and overpressure. The primary hydrocarbon reservoir in the Balikpapan Formation within the Sanga- sanga axis at Field X consists of sandstone. Drilling disturbances, particularly in the lower intervals of this reservoir, often occur due to overpressure. The main challenge encountered in this reservoir is mud losses. The objective of this study is to develop the Pore Pressure and Fracture Gradient characteristics and its relation to the geological environment. Furthermore, the distribution of Sand (Interval-I) is determined, which is the primary cause of losses due to production. Besides that, the parameters used to create optimal fracture gradient is also defined. Thirteen wells in this field were examined to identify the controlling factors of pore pressure. This study integrates wireline logging, velocity, mud logs, pressure tests, drilling parameters and event which are subsequently processed for determining shale points, Normal Compaction Trend (NCT), calculating overburden gradient, and estimating pore pressure using the Eaton method. From the analysis result, the distribution of overpressure and the generating mechanism of overpressure are determined. This study also carried out analysis to determine overpressure and depleted Sandstone (Interval-I) distribution. Subsequently, facies and depositional environtment analysis are conducted, followed by modelling Sandstone (Interval-I) and determining Sandstone’s poisson ratio from loss data and shale’s from leak of test data for fracture gradient estimation. Overpressure is found in Interval-I with magnitude of 4000-4700 psi, which corresponds to delta plain to delta front depositional environment. Top of overpressure is observed shallower in the southern than northern due to geological structure conditions. The generating mechanism of overpressure is caused by loading and hydrocarbon generation. The experienced loss in overpressure zone, caused by reservoir production from the initial pressure of 4475 psi and has depleted to 373 psi. From the sandstone distribution model, the loss sandstones are a connected fluvial channel in southern ward. It is also observed several unconnected channel sandstones that did not experience loss. Poisson ratio parameter for sandstone is 0.35, which is calibrated from the loss event with minimum fracture gradient in Interval-I is approximately 4772 psi. It is expected that the understanding of pore pressure and Sandstone (Interval-I) distribution could be used to increase the success ratio for optimal drilling planning, including to choose effective casing design, mud weight, and appropriate total depth.

The distribution of Kaliwangu Formation sediment in West Java generally follows the structure of Java fold thrust belt, which directed west-east. The Java fold thurst belt was efectively formed during Pleio-Pleistocene tectonics events, in which all of the Cenozoic sediment were deformed by compression stress in north-south direction. In Ujungjaya area, Kaliwangu Formation has northwest-southeast direction, while in Pasir Malati, the formation was arced relatively in north-south direction. Kaliwangu Formation distribution in Ujungjaya was influenced by the massive compression tectonics occurred in Java. This tectonic event were occurred during Pleio-Pleistocene which resulted in Java thrust fold structure pattern including Baribis Faults. Unlike in Ujungjaya, the distribution of Kaliwangu Formation in Pasir Malati was arced in north-south direction which caused by its fold structure. There is no indication of regional fault in Pasir Malati area although a lot of fault structure was found as a part of regional structure.

In the southern part slope of Gunung Karang in Pandeglang, there are many well-outcrops of volcanic materials that developed during Quaternary. The deposits represent various lithofacies both vertically and laterally.In general the lithologic characteristics that are found in the study area can be grouped into three units, (1). Tertiary sedimentary rock, which is consists of tuffaceous mudstones interbedded with fine-grained tuffaceous sandstone and siltstone, (2) primary volcanic product consist of andesite lava flow, volcanic breccia/agglomerate, and pyroclastic rocks (ash tuff, lapilli tuff, bomb/block, and lapilli tuff breccia, and (3) secondary volcanic products, which is consisting of laharic breccia and coarse-grained thick-bedded sandstone.In general the deposits become younger to the top of topography (Gunung Karang), but locally the deposits are most likely overlapping each other’s.Keywords: Volcanic deposits, Gunung Karang

Religious tourism in Makbaroh Ki Gede Madun Jaya tends to be of little interest, even though there are many during kliwon Friday nights. However, it tends to decline on weekdays and needs development. The purpose of this observation or research is to find out the existing problems and find efforts to overcome the existing problems. The method used in this research is descriptive qualitative with data collection techniques in the form of interviews, observation, and documentation. Interviews were conducted with Kuncen Makbaroh, and visitors or pilgrims. The results found from this study are the findings of joint efforts between the village government and the community in developing religious tourism. Based on the results of the above research, the authors conclude: 1) there is togetherness between the government and the community to jointly develop religious tourism as local wisdom in the village of Guwa Kidul, 2) To commemorate Ki Madun Jaya's services in the early spread and develop Islamic teachings in Guwa village South.
