Abstract
Abstract The expandable openhole liner system is used as solution for operational challenges associated with borehole instabilities, pore pressure/fracture gradient issues and the effect of salt or subsalt formation. All these operational challenges produce pre- mature downsizing of well's tubular. While drilling in the Kupal oilfield located in south west of Ahwaz, Iran, an isolated extreme thief zone was penetrated resulting in a possible unplanned conventional liner was run, decreasing further deeper hole sizes. The smaller size of liner would have cause problems such as lower reservoir production rate and putting limitations on running measurement tools to evaluate the reservoir. Because of these aforementioned negative effects of running a conventional liner it was instead desided to run an expandable openhole liner. This paper discusses challenges and solutions for running the first expandable openhole liner in Iran to reach a proposed target with the planned hole sizes as well as a cost evaluation and comparison of two wells, one using expandable open hole liner and one using conventional liner.

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 it
