| Abstract |
The UK Geoenergy Observatories project (UKGEOS) is developing a subsurface Observatory in Glasgow for research and innovation in mine water heat and heat storage. This report provides an overview of the timing and tasks adopted in borehole construction and initial testing. It has been subdivided into three stages: planning/feasibility, exploration and appraisal. The fourth delivery or development stage, which is to construct the above ground infrastructure for mine water circulation and thermal perturbation, is ongoing in 2021 and is not covered in this report._x000D_

Land availability, prior land use and environmental protection were key constraints in establishment of the Observatory, as well as subsurface geological factors. These are likely common to many mine water heat projects. Observations made during construction of the Glasgow Observatory are summarised to help to de-risk future mine water projects. These include difficulties associated with completing boreholes through sands and gravels in superficial deposits, and the challenge of identifying the type and size of mine workings during drilling. A key learning was the value of using a downhole optical or acoustic camera to better understand the nature of mine workings prior to screen installation. |
