pressure PD) determines the permeability, i.e., a high displacement pressure corresponds to a low permeability. However, permeability difference could reach one or two orders of magnitude for samples with similar and PD in tight sands. A typical example is given in Figure 1, where two...

Here, the nozzle has non-wetting conditions, which leads to defining the inner diameter as its typical length scale. These observations suggest that stability of the process is related to the aspect ratio of the jet, and that its break-up could be caused by a Rayleigh-Plateau type ...
d Top view of a typical prestretching crack Full size image CATSS has excellent stretchability and flexibility. Tensile tests were carried out on neat TPU mats and CNT@AgNW/TPU composite mats. The stress–strain curve obtained at a tensile rate of 5 mm/min is illustrated in Fig. 4a. ...
Based on an analogue between the process of oil and saturation of a reser- voir and the capillarity curve,this paper gives an analysis on the factors in the effecting determination of oil and gas saturation by means of the capillari- ty curve technique such as actual production pressure differ...
Finally, (Muradov et al., 2018a,b) extended the DP model to AWC wells for stratified-reservoir waterfloods with piston-like oil-water displacement behaviour typical of fluids with a mobility ratio close to unity. Their solution included the non-linear, pressure versus flow rate performance of ...
(CB2 biosensor, yWS2345), we characterised the dose-response with 2-AG and AEA over a range of concentrations. AEA presented a more typical sigmoidal dose-response (Hill slope = 0.8), with a greater than 2-log concentration range between 10 % and 90 % of the response (operational range)...
