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 ...

Dynamic step BI-RRT UAV path planning algorithm

Journal of Hebei University of Science and Technology, 2019
To solve the problems of traditional RRT algorithm, such as slow convergence and long path length, the dynamic step BI-RRT algorithm is proposed. The sampling efficiency of the RRT algorithm is improved by using a target-oriented sampling strategy.
