Application of Submersible Linear Motor in Directional Well
Shiyou jixie, 2019 It is more and more common to use large well pad to produce low-permeability reservoir. However, the complex deep well trajectory and low liquid volume are the characteristics of such oilfields.

Ion Concentration and Voltage Imaging With Fluorescent Nanodiamonds
Advanced Materials, EarlyView.We demonstrate reversible switching between the fluorescent NV0 and the dark NV+ state, in sub‐30 nm FNDs via surface oxidation and hydrogenation, respectively. In an electrochemical cell, we show that the fluorescence from hydrogenated particles enables all‐optical imaging of voltages and ion concentrations at the micrometer scale.
