Abstract

fetched live from OpenAlex

Abstract Increasing concerns over health and safety, as well as environmental impacts of diesel oil-based muds in land-based drilling applications, has prompted a search for safer drilling mud base fluids. There are two challenges. First, the drilling fluid must satisfy technical requirements. Second, it must reduce environmental health and safety risks. This paper summarizes research aimed at finding a synthetic base fluid that satisfies both requirements. Laboratory studies evaluated the degradability of diesel and synthetic base fluids, and the toxicities of the same fluids to a range of terrestrial flora and fauna. More specifically, biodegradation, seed germination and root elongation of two plant types, earthworm survival, and response of bioluminescent bacteria (Microtox™) were determined in a typical landfarm receiving soil containing the test fluids. Olefins demonstrated the fastest biodegradation and lowest toxicity after bioremediation, whilst iso-paraffin fluids and mineral oil degraded less readily and developed extreme toxicity during the three-month bioremediation period. Although 71% of the diesel oil disappeared through volatilization and biodegradation, it remained extremely toxic after bioremediation.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
