Abstract

See full text

A device for measuring strain on the exterior of a pipe includes a body comprising a top portion and a bottom portion; one or more elastically deformable members coupled between the top portion and the bottom portion, wherein each of the one or more elastically deformable members have an outer contact surface and an inner non-contact surface. One or more sensors are disposed on the inner non-contact surface of one or more of the elastically deformable members. The sensors, during use, provide data that can be used to determine changes in strain on the exterior of the pipe. In another embodiment, one or more sensors are embedded in, or attached to, a casing disposed in a wellbore. In an embodiment, a method includes pressurizing or depressurizing the wellbore with a fluid and measuring the strain induced in the casing (or in an open wellbore) in response to this change in wellbore pressure.
