Abstract

This document describes the drilling, completion and testing of the pilot borehole (DEL-HTO-P01), which will later be utilized as a monitoring well for High Temperature Aquifer Thermal Energy Storage (HT-ATES). The work includes all materials, components, tools, and services that are related to the preparation, delivery, installation, measurement, and completion of the components belonging to the test drilling and monitoring well. The following analysis combines various data sources to characterize the subsurface for the Delft Demonstration site (WP1). The location of the DEL-HTO-P01 is demonstrated in Figure 1, which is located at RD-coordinates X = 85,257 m, Y = 445,757 m.
