Abstract

Smartphone technology, especially Android smartphones, has advanced quickly in terms of their function as smart and communication devices. Their capacity to function as remote control tools, enabling users to view and manage electronic gadgets via an Internet connection, is one notable advancement. Through the use of the Internet connection as a bridge between devices, smartphone-based remote control indirectly makes it easier to monitor and manage electrical gadgets. Uncontrolled electricity use and instances of high power consumption that occur when people forget to turn off equipment provide a challenge. The author suggests using the prototyping method, in which a prototype is created at the beginning stage for later development, to overcome this problem. Through

Abstract

The Kutai Basin is a region with complex geological characteristics, which complicate formation pressure prediction and pose drilling risks such as overpressure. This study aims to analyze the relationship between porosity and overpressure using well log data, including sonic (DT), resistivity (ILD), neutron porosity (NPHI), and density (RHOB) logs. Overpressure is calculated based on the difference between actual pore pressure and normal hydrostatic pressure, supported by vertical stress estimation. The analysis results indicate that overpressure zones occur within specific intervals, particularly in the Pulau Balang Formation, which is dominated by impermeable shale lithology. These overpressure zones are characterized by high DT values, low ILD readings, and sustained high porosity despite increasing depth. This suggests that the overpressure is caused by undercompaction (Disequilibrium compaction), where rapid sedimentation rates hinder the expulsion of pore fluids. A Dutta crossplot confirms the dominance of smectite minerals that have not yet transformed into illite, reinforcing the indication that the rocks have not undergone significant chemical compaction. The correlation between preserved porosity and overpressure zones provides critical information for mitigating drilling risks and optimizing reservoir development.
