Abstract

fetched live from OpenAlex

ABSTRACT Blocking high permeability zones of reservoirs by hydrogels, and diverting the injected fluid towards the unswept zones of the reservoir is a promising method for improving the overall oil recovery in waterflooding and carbon dioxide flooding processes. A polymer gel treatment typically involves the injection of a solution of a medium to high molecular weight polymer and crosslinking agents into the high permeability zones or fractures. The polymer reacts with the crosslinker to form a three-dimensional gel network. KUSP1 biopolymer in sodium hydroxide solution produces a delayed gel system with orthoboric acid. The gelation time varies depending on the concentration of the orthoboric acid and temperature. Syneresis of this gel was studied in bottle tests as well as in the porous media. Samples of KUSP1–boric acid gel lost more than 80% of their initial volume in bottle tests after 250 h. Also, it was observed that this gel, when placed in a sandpack, lost up to about 50% of its initial volume. However, the high values of syneresis did not have a severe effect on the performance of the gel in porous media. KUSP1–boric acid gel was tested for reducing permeability to carbon dioxide and water in a series of tests conducted in a Berea sandstone core. It reduced the carbon dioxide permeability from 164 to 26 md and brine permeability from 420 to 90 md.

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.
