Geostorage represents a groundbreaking approach utilizing the earth's underground layers to store hydrogen or sequester CO2 and other undesirable fluids. This method involves injection into or production from underground formations. Prior to commencing a Geostorage project, identifying the optimal underground formation is crucial. A key aspect of this groundwork entails assessing the capacity and injectivity/productivity of subterranean storage.

To evaluate these characteristics, wells are drilled through the formations, and well testing is conducted. The objective of well testing is to collect downhole data, primarily pressure transient data, which reflects changes in downhole pressure due to fluid flow. Interpreting this data enables students to assess the formation's capacity and productivity/injectivity. The method of data collection and interpretation varies based on host rock and fluid properties.

This course aims to equip students with fundamental skills in data collection and evaluation from underground reservoirs. By the course's conclusion, students will proficiently design formation evaluations, interpret gathered data, conduct formation analyses, and generate technical reports. These reports should serve as a foundation for senior management to greenlight a Geostorage project.
