Evaluating Fluid/Rock Interactions for Energy Storage in Salt Caverns: Part I: Brine–Rock Salt Interactions
Bibliographic record
Abstract
Understanding the interaction between brine and impure salt rock is essential for the long-term stability of salt caverns used in energy storage. This knowledge is crucial for optimizing the design and ensuring the structural integrity of storage systems in bedded salt formations. We conducted immersion and batch reaction experiments to investigate the effect of brine on the integrity of the impure salt rock. We evaluated the interaction between impure salt rock and brine with salinities of 0 ppm, 50,000 ppm, 150,000 ppm, and 250,000 ppm over a 30 day period and observed significant weakening and cracking of the samples. Based on acquired SEM images of identical spots before and after reactions with brine, we observed that the presence of brine creates oversized pores of up to 50 μm. The results suggest that the damage to impure salt rock is attributed to (1) the combined dissolution and detachment of embedded halite crystals and (2) the combined dissolution and detachment of calcite and dolomite grains.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
