DYNAMIC SWEEP EXPERIMENTS ON A HETEROGENEOUS PHASE COMPOSITE SYSTEM BASED ON BRANCHED-PREFORMED PARTICLE GEL IN HIGH WATER-CUT RESERVOIRS AFTER POLYMER FLOODING

Heterogeneous phase composite (HPC) flooding technology that is based on branched-preformed particle gel (B-PPG) is an important technology for enhancing oil recovery in high water-cut reservoirs.In this paper, we conducted a series of visualization experiments under the condition of developed high-permeability channels after polymer flooding, with

The genetic plasticity of Staphylococcus aureus has facilitated the evolution of many virulent and drug-resistant strains.Here we present the sequence of the 2.74 Mbp genome of S.aureus SG511-Berlin, which is frequently used for antibiotic screening.Although S.aureus SG511 and the related methicillin-resistant Slim Wallet S.aureus MRSA252 share a h

In bats, the wing membrane is anchored not only to the body and Cross Dancing Necklace forelimb, but also to the hindlimb.This attachment configuration gives bats the potential to modulate wing shape by moving the hindlimb, such as by joint movement at the hip or knee.Such movements could modulate lift, drag, or the pitching moment.In this study we
