Enhanced oil recovery (EOR) is the recovery of oil remaining in a reservoir after primary and secondary recovery methods because it has been exhausted or is no longer economical, using thermal, chemical or mixed gas processes. Most conventional methods are not suitable for extracting oil from high temperature and high pressure (HTHP) reservoirs due to chemical degradation in the environment. Alternatively, electromagnetic (EM) energy is used as a thermal method to reduce oil viscosity in reservoirs, thereby increasing oil production. The application of nanotechnology in EOR is also investigated. In this study, we investigate a non-invasive method by injecting dielectric nanofluids into an oil reservoir simultaneously with electromagnetic irradiation, with the aim of increasing oil production by causing disruption at the oil-water interface. During core displacement tests, ZnO and Al2O3 nanofluids were shown to obtain higher amounts of residual oil than commercial sodium dodecyl sulfate (SDS) surfactant without EM irradiation. With EM irradiation, more residual oil is obtained compared to without irradiation. It has also been shown that changing the viscosity of dielectric nanofluids during electromagnetic irradiation increases sweep efficiency, resulting in higher oil recovery.

Sukomulyo is a village located in Kaliwungu Selatan District, Kendal Regency, most of whose residents work as farmers. The rice fields in Sukomulyo village are irrigated using river water which is taken directly from the Waridin River with a diesel water pump. The process of irrigating the rice fields takes a long time, so the water pumps are simply left alone by the farmers because they are doing other activities. Often farmers forget to turn off the water pumps they turn on, resulting in wasteful use of river water and fuel. When the dry season arrives, there could be a decrease in the river water discharge to the ground which has the potential to result in farmers not being able to irrigate their rice fields with water. To overcome this problem, the Sukomulyo farmer group in collaboration with the PPL (Agricultural Extension Worker) of Kaliwungu Selatan District built a water pump house which is used for their rice field irrigation needs. With the construction of the water pump house, it is hoped that it can irrigate farmers' rice fields during the dry season and can increase agricultural production in Sukomulyo Village and can reduce farmers' worries when the river water does not flow
