A Novel Modified Petroresin Particle (MPRP) With Enhanced Oil–Water Selectivity for Cold Production in Heavy Oil Reservoirs

Advanced Functional Materials, EarlyView.
A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

20 kW Monolithic Fiber Amplifier With Directly Dual-Wavelength Laser Diodes Counter Pumping

IEEE Photonics Journal
In this study, we demonstrate a high-power ytterbium-doped fiber laser (YDFL) based on laser diodes (LDs) directly pumping scheme. Tandem pumping and LD direct pumping are two common schemes for generating high-brightness laser output in YDFL.
