Evaluation of recrosslinkable preformed particle gel (RPPG) as a fluid loss control material during drilling operations
… of a re-crosslinkable preformed particle gel (RPPG) has been conducted to determine the extent to which it can be used to control drilling fluid losses during drilling operations. The RPPG consists of swellable gel particles that can self-crosslink to form a strong bulk gel in fractures to form …

Investigation of Recrosslinkable Preformed Particle Gels for Natural Gas Conformance Control
<p>"Recross linkable Preformed Particle Gel (RPPG) is a novel type of preformed particle gel in which particles can bond together to form a strong bulk gel system after being placed in the target formation. In this research, I systematically evaluated the feasibility of using this product to …

EVALUATION OF NOVEL PREFORMED PARTICLE GELS FOR CONFORMANCE CONTROL AND ACID STIMULATION THROUGH CORE FLOODING TESTS
… and Re-crosslinkable Preformed Polymer Gel (RPPG). DPPG is designed to be a temporary plugging agent for acid stimulation and can self-degrade into a water-like fluid. RPPG is designed for reservoir sweep efficiency improvement and can re-crosslink to each other and form an immobile bulk gel …

Cardiac Signals: Remote Measurement and Applications
… We report beat-to-beat accuracy of remote PPG (rPPG) in comparison to conventional average heart rate. The beat-to-beat accuracy is required for applications related to heart rate variability (HRV) and affective computing. The algorithm has been tested on two datasets, one with static …

Plugging performance of preformed particle gels in fractures and its influencing factors
… a novel re-crosslinkable preformed particle gel (RPPG) was evaluated as an agent specifically designed for healing large fractures. The evaluation of oxidizing breakers for the re-crosslinked RPPG was provided. Among the tested breakers, NaOH-activated Na<sub>2</sub>S<sub>2</sub>O<sub>8</sub> was …
