Drill core is a vital resource for subsurface characterisation and informs process understanding. However, it is expensive to collect and as a result, the geoscience community increasingly relies on data from legacy core to address today\x92s energy challenges. Many countries store geological materials collected over decades in national archives. In the UK, over 600 km of drill core is currently stored at the UK national core repository which covers a breadth of the UK\x92s geology, including those targeted for resources, energy and waste storage. The challenge is to maximise the value of these analogue archives and new core when deposited - improving access to materials and associated data, whilst simultaneously maximising preservation to ensure optimised use, now and in the future. This paper summarises the BGS approach to characterise drill core more efficiently and consistently using a multiple-technique core scanning approach set within a project-specific core scanning workflow to increase core data acquisition and complement traditional core characterisation practices. Thus, creating a digital record of the core, preserving it beyond its physical lifetime and improving accessibility. This paper highlights the benefits and challenges of this long-term endeavour, especially in making the data open access and discoverable.

A core repository is a physical record of a country's or commercial organization's subsurface wealth. Some of the largest core repositories hold 1000s of km of core material and it is a challenge to turn this physical archive into an accessible digital resource for all. Non-destructive multi-sensor core logger (MSCL), hyperspectral and X-ray imaging techniques offer a unique chance to rescue valuable data trapped within core samples, improving the way that a core repository delivers data to academic or industrial end users. Here we present a case study of an archived petroleum core acquired in 1985 at the Osprey Field, United Kingdom Continental Shelf (UKCS). Data from the UK National Data Repository are augmented by a MSCL, Hyperspectral and X-ray dataset that is uploaded into a cloud-based digital repository. The data were analysed using a multi-variant analysis to reclassify the original lithological interpretations uncovering a greater proportion of clay and cemented horizons than was previously interpreted. A workflow is established to optimize the use of legacy cores and exploit the abundance of data trapped within the core repository using continuous multi-sensor core scanning and imaging data which are stored within the virtual environment for visualization and access to all.
