Marine Vibrator Milestone: A Pilot Seismic Survey
Bibliographic record
Abstract
Abstract The Marine Vibrator Joint Industry Project (MVJIP), sponsored by TotalEnergies, Shell and ExxonMobil, completed a successful pilot survey in Q3 2022 using two Integrated Project Node (IPN) Marine Vibrators in an offshore European open water setting. The IPNs were deployed in two configurations: one under tow, and the other stationary at each shot point. Various sweep types and duty cycles were also tested. An airgun source of equivalent energy size was also used for comparison. Throughout the pilot the IPNs demonstrated exemplary performance. There were no HSE incidents during the project, nor was there any technical downtime related to the IPNs. Moreover, real time quality control results were able to show the IPNs high fidelity with respect to the pilot sweep and excellent sweep-to-sweep repeatability. A fast-track processing sequence was completed, which showed that the IPNs have been able to image the subsurface very well including steeply dipping reflectors. This demonstrates the progress that has been achieved by the MVJIP over the last 10 years and gives a real impetus to continue the development of the marine vibrators into a commercial source. The next steps will be to complete a more comprehensive full processing sequence on all the lines to extract the best possible images.

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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
