co2 injection is an effective technique for improved oil recovery in light oil reservoirs, especially for water flooding abandoned reservoirs. in this study, the lower part of es1 reservoirs in pucheng oilfield was introduced as the target reservoir. by studying the minimum miscible pressure in co2 flooding, the reservoir could achieve miscible flooding. long core displacement experiments prove...

In vitro assays have contributed important insights into the mechanisms of RNA metabolism in cells. A growing collection of microscopy techniques is allowing the measurement of macromolecular binding and complex formation in the context of a real cell. We will first discuss two of the more established techniques. Fluorescence resonance energy transfer (FRET) identifies binding partners, pairs o...
