Inflatable CT Conveyed Selective Well Testing System for Logging Openhole and Horizontal Wellbores: Development and Use
Bibliographic record
Abstract
Abstract Quantitative production logging of openhole and horizontal wellbores presents a challenge for conventional logging tools and techniques. The complicating factors of horizontal logging are primarily related to low fluid velocities and stratified flow. Openhole horizontal completions further the challenge by increasing the opportunity for tool fouling and fill obstruction, creating abrasive running environments, and finally complicating interpretation with unknown hole geometries. To address these challenges, a new diverter logging system based on inflatable packer technology has been developed. The tool is inflated at discrete locations in the horizontal section so that all flow at each stop is diverted through rock-excluding screens and past conventional memory logging tools in a carrier. Pressure drop through the tool is minimal, and the fixed internal diameter carrier allows for high resolution logging over a wide range of rates. Developing a method to allow packer setting and resetting in wire/umbilical-free Coiled Tubing (CT), while constantly maintaining a production or injection path through the tool, called for innovative engineering. The tool has been run in nine wells to date. This paper will discuss the need, development, and field results of the new inflatable packer logging system.

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.
