Geometry Matching Technology of Non-Repeating Acquired Time-Lapse Seismic Data Processing
Bibliographic record
Abstract
Different from the normal time-lapse seismic technology, time-lapse seismic technology with non-repeating acquired data utilize existing multi-period seismic data with different geometries at different exploration period of the same area. Not only the change of reservoir parameters cause the property differences of two-period data but also the difference of geometries, this uncertainty has become a fundamental problem in application of time-lapse seismic technology. In order to solve this problem, this paper takes advantage of the 3D Gaussian beam simulating method for illumination analysis of reservoir model, then we analyzes the impacts of various parameters of geometry on receiving energy of reservoir, finally we put forward the main factors affecting imaging of reservoir : the distribution of offset and azimuth. Basing on this conclusion this paper established the work flow of geometry matching for non-repeating acquired seismic data. By processing real data in S block, this technology could effectively reduce the affects of geometry difference and obtain an obvious result, and also provide an idea to increase value of multi-period seismic data in old oil field.

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; a candidate call from one teacher head, not a consensus.
