Abstract

fetched live from OpenAlex

Introduction Cold production is a nonthermal recovery mechanism in which a progressive cavity pump simultaneously produces oil, water, gas, and sand. This extraction decreases the reservoir pressure to values less than bubble point; therefore, gas comes out of solution and forms a foam-like material called foamy oil. On the other hand, because of sand production, high-porosity and high-permeability channels known as wormholes are created with diameters ranging from 10 cm to as much as 1 m (Tremblay et al., 1999). It is very important to avoid drilling into the worm-holes; therefore, petroleum engineers need to know the location of wormholes and the extent of depleted zones. Fortunately, the reservoir undergoes significant changes during cold production that we can monitor using seismic information. In this modeling study, we evaluate the influence of changes in porosity and foamy-oil effects caused by cold production on seismic data.

Teacher imitation

Not 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.
