Production prediction method of horizontal wells in tight gas reservoirs considering threshold pressure gradient and stress sensitivity

Journal of Petroleum Science and Engineering, 2020
This study is aimed at the problem of specific seepage mechanisms, such as the threshold pressure gradient and stress sensitivity, in tight gas reservoirs, which have a tremendous influence on a gas well production prediction.

Horizontal gradient polyacrylamide gel electrophoresis

ELECTROPHORESIS, 1981
AbstractA simple Technique for horizontal gradient polyacrylamide gel electrophoresis (PAGE) in discontinuous buffer systems is described, in which one‐dimensional, two‐dimensional and double one‐dimensional separation patterns can be obtained. The advantages of this technique are: (i) that samples can be applied by overlaying on a variable broad area ...
