Water balance between production and injection in geothermal water dominated reservoir is essential to maintain the sustainability of steam power plant production. Thus in the planning of the steam production, a natural injection calculation must be completed first. This natural substance is infiltration water into a reservoir that comes from rainwater inside the reservoir of the Geothermal Electricity Power Plant (GEPP). The method of knowing natural injection is by analyzing the availability of water in the GEPP watershed, the area of the river flowing into the reservoir is 22,21 km2, with annual rainfall around 3802 mm. One of the calculation methods used is FJ. Mock method. This method transforms rainfall into run-off based on the concept of a hydrological model. Water availability analysis is in monthly rainfall. From the calculation results, the monthly average infiltration is about 650 kg/s, and the annual total is about 7,760 kg/s. Consequently, the total annually mass production must not exceed 7,760 kg/s, if mass production exceeds infiltration, need to do injection through injection wells.

Java is an island which is considered to be quite disaster-prone. This terminology comes from the fact that along the island, we can find subduction tectonic activities which is also an epicenter. Some earthquake phenomena can be extremely destructive because of the existence of active fault as the vibration medium. Therefore, it is very important to do active fault mapping in Java island. In East Java province, there is an active fault which has been researched many times called Grindulu Fault. It is an active fault located in Pacitan Regency, East Java Province. It is a left-lateral fault. It is well exposed 500m alongside Grindulu river. However, the continuity of Grindulu northward is not well identified due to limitation of outcrop. This research was conducted to see how far the continuity of Grindulu northward. This research was started by satellite imagery survey to view areas where the existence of Grindulu fault may be found. Furthermore, field data acquisition was done on the marked areas. Field data obtained were in the form of fault slip data which were then analyzed using Wintensor software to see their kinematics. Based on the field data, the continuity of Grindulu fault can be found in three other areas which are Bakalan village, Wonogiri village; Pohijo village, Ponorogo regency; and Kruwe village, Megetan regency. Those exposed faults are strike-slip faults which are segments of massive NE-SW fault. This major fault is proposed with the name of Magetan-Pacitan active fault. The understanding of this active fault is expected to be reference for disaster mitigation in those areas.

Drilling mud is the most important part in drilling activity. Drilling could work fluently, safely, and economically on fluency by system and condition of drilling mud. It means the mud system and the physical properties of the slurry conform to the required specifications. There are some kinds of drilling mud that can be used in oil and gas drilling operation, such as water base mud and oil base mud. In terms of economical objective, water base mud is usually used in drilling process.The purpose of this study is to conduct laboratory research of the effect of various temperatures on the characteristic of mud system of low solid mud by adding biopolymer and bentonite extender. This research uses roller oven method as a medium for simulation to condition the mud as close as possible to the condition in wellbore to see the change of physical properties of sludge at various temperatures.The result found is that the higher the temperature, the lower the drilling mud physical properties such as density, viscosity, plastic viscosity, yield point, dial reading 600 RPM, dial reading 300 RPM, and gel strength. However, it is found that not all the physical properties decrease.
