Abstract
Summary The drill-bit generates significant elastic wave energy whose ray paths are unique relative to those induced by standard surface seismic. Provided that we understand the challenges associated with characterizing the source radiation properties of the drill bit- rock interaction, the data arising from seismic-while-drilling (SWD) are complementary to surface data, and have the potential to enhance geophysical evaluation of the subsurface. Hence, it brings an opportunity to address seismic illumination issue by adding new measurements into the imaging problem. In this paper, we carry out a feasibility study of the SWD method to mitigate the illumination problem in imaging. Source signature estimation of the drill bit- rock interaction is a necessary step for pre-stack migration of the SWD dataset. To do so, we applied a multichannel sparse blind deconvolution technique to estimate the signature and later, we feed the signature into the SWD imaging workflow. Finally, we merge the SWD image with the surface seismic migrated section to improve the illumination of the subsurface features. The efficiency of the workflow is tested against Sigsbee2a model.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
