Abstract

Well logging dapat digunakan untuk mengidentifikasi zona produktif, membedakan antara minyak, gas, atau air di dalam reservoar, dan memperkirakan cadangan hidrokarbon. Salah satu metode dalam pendekatan parameter karakterisasi reservoir yang cukup efektif adalah dengan menggunakan analisis petrofisika. Pada penelitian ini melakukan analisis petrofisika berupa analisis kualitatif serta analisis kuantitatif dengan tujuan untuk mengetahui nilai volume shale, porosity, dan saturasi air, kemudian menghitung ketebalan reservoir berdasarkan nilai net pay. Berdasarkan analisis kualitatif didapatkan 2 zona reservoir yaitu pada interval kedalaman 1112-1116m dan 1211-1219m. Berdasarkan analisis kuantitatif dihasilkan nilai volume shale pada zona reservoir A dan B yaitu 17,7 – 26,9% dan 8,5 – 16,6%, kemudian nilai porositas total pada zona reservoir A dan B yaitu 16,5 – 22,7% dan 23,1 – 25,9% sedangkan nilai porositas efektif pada zona reservoir A dan B yaitu 15 – 20,6% dan 22,6 – 25.7%. Kemudian, untuk nilai saturasi air total pada zona reservoir A dan B yaitu 34,4 - 42% dan 28,6 – 36,4%, sedangkan untuk nilai saturasi air efektif pada zona reservoir A dan B yaitu 23,1 – 25,9% dan 22,6 – 25,7%. Kemudian didapatkan ketebalan reservoir yang berisi hidrokarbon (netpay) yaitu sebesar 3,058 m yang berada pada Formasi Tualang. Maka zona reservoir yang memiliki prospek hidrokarbon terdapat pada zona reservoir A pada Formasi Tualang.

Abstract

The tsunami is a worrisome natural disaster typically in coastal areas, including Batu Balak Village in South Lampung. The Selat Sunda tsunami on December 22 2018 hit the Batu Balak Village residents and resulted in material and non-material losses. The unpreparedness of the residents who experienced this incident is a reminder of the urgency of the need to increase community preparedness in facing this threat. On this basis, service activities were carried out to strengthen mitigation and education on tsunami emergency response in Batu Balak Village, South Lampung. This service activity aims to strengthen the mitigation process and educate the community regarding the potential for a tsunami disaster in the Batu Balak area. Another purpose is to increase public knowledge of disaster management. The methods used in this service are needs analysis, solution design, program assistance, and implementation. Based on the problem analysis, we carried out a workshop event on tsunami disaster mitigation, how to increase the social economy by utilizing geotourism, and made a recommendation map for tsunami evacuation routes and zones. The workshop event was attended by several residents and community leaders. The results obtained from this activity are an increased understanding of the people who present regarding the tsunami disaster, what mitigation processes need to be implemented when a disaster occurs, and how to handle the loss after the disaster.
