Abstract
Abstract A total of six high rate water packs were installed in two wells utilizing a single trip, multi-zone gravel pack technique. The multi-zone gravel pack tool system allowed the installation of multiple gravel packs with a single run into the wellbore.1, 2, 3 This gravel pack system was chosen to reduce rig time and to minimize fluid loss into the low pressure, high permeability gas sands. In this high permeability reservoir, frac packing did not appear necessary for stimulation. The multi-layered reservoir and low strength rock made it highly unlikely that single, planar fractures could be created that would grow and connect up all the individual sands. Emphasis was placed on completion efficiency to minimize the effects of non-Darcy flow that severely limit the productivity of conventionally completed wells. This paper describes the nodal analysis and well test evaluation techniques used to assess the rate limiting effects and completion inefficiencies of existing completions in this field. Also presented are single-trip, multi-zone gravel pack completion design and installation techniques that provided two to five times the productivity over conventional completions in a mature, low pressure, low temperature gas field. Sustained deliverability from the two completed wells has deferred both rig and non-rig wellwork for several years.

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
