Offset pressure response

Abstract

A downhole check valve may be used in a wellbore to allow a variety of pressure diagnostics to be easily captured and compared within a single monitor well. Pressure responses from below the check valve are open to the formation and provide detailed stress shadowing, poroelastic pressure response, and other sensitive pressure measurements from the open toe, allowing ingress from the wellbore while additional responses can be obtained above the check valve provided the pressure events below do not overcome the pressure above or the spring setting of the valve. This allows for an increase in available data points from the monitor well and a direct comparison of geomechanical and mechanical responses.
