Abstract Low permeability tight sandstone reservoirs have a high filtrational
resistance and a very low fluid flow rate. As a result, the propagation speed of
the formation pressure is low and fluid flow behaves as a non-Darcy flow, which
typically displays a highly non-linear behavior. In this paper, the characteristics
and mechanism of pressure propagation in this kind of reservoir are revealed
through a laboratory pressure propagation experiment and through data from an
actual tight reservoir development. The main performance mechanism is as follows: A new pressure cage concept is proposed based on the pressure variation… More >
