Multicomponent seismic modeling and analysis for CO2 storage in the Redwater reef, Alberta, Canada
Bibliographic record
Abstract
The Devonian Redwater reef, in Alberta, Canada, is being evaluated for geological storage of CO 2 for the Heartland Area Redwater CO 2 Storage Project (HARP).The reef complex is one of the largest Devonian reefs in the Western Canadian Sedimentary Basin and is the third largest oil reservoir in Canada.It is located close to large sources of CO 2 in the Redwater-Fort Saskatchewan-Edmonton region.The study characterized the Redwater reef, identified the reef margin, and mapped the facies variations within the reef.The seismic response of the reef to the CO 2 saturation in the Leduc Formation was investigated.Fluid substitution and seismic modeling were undertaken to generate PP and PS synthetic seismic data to study the consequences of CO 2 saturation on the seismic response of the various reef facies and formations below the reef, based on seismic attributes and character.Common shot ray tracing and finite-difference modeling was undertaken to evaluate variations in the seismic response of the Redwater reef across the southern margin of the reef for CO 2 saturation in the Upper Leduc interval.The input geological model was based on well data and depth-converted seismic data from the interpretation of legacy 2D seismic lines in the area.Seismic reflections display positive structure below the reef in time sections due to the lateral velocity change from on-reef to off-reef, but are corrected in the depth sections.Terminations and the lateral position of the Upper Leduc and Middle Leduc events are clear on the pre-stack time-migrated sections and a modest improved on the depth-and opportunity to proceed in my high education.Second, I would like to recognize a few of people who made this thesis possible.

How this classification was reachedexpand
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.
