A ground penetrating radar stencil and system for using the same is provided. The stencils are reusable. The stencils are foldable, allowing for storing and transportation. A first data collection grid stencil is used to mark a grid followed by alternative target marking stencils used to mark utility line and structural support lines. Indelible stencil paint/ink is applied on and through the stencils onto the concrete surfaces to provide for a permanent, standardized and consistent marking of critical embedded infrastructure. The system allows for a uniform collecting and recording of the scanning data results for future reference and work in the same area.

The present invention describes a tag comprising a magnetic element in the form of a microwire of 80-250 microns with giant magnetoimpedance which, when joined to an object, allows for the wireless detection of same by modulating the reflectivity of the microwire. Detection is performed by using a system that emits an electromagnetic wave that has a frequency between 1 and 20 GHz and a low frequency magnetic field (0.01-50 Hz), and detects the modulation of the reflectivity of the microwire. Thus, objects at distances greater than 1 m can be detected.

Methods and systems are presented in this disclosure for determining information (e.g., visual information) about locations of different fluids flowing along a casing in a wellbore. A plurality of radio frequency (RF) micro-electro-mechanical system (MEMS) tags is placed in a plurality of fluids flowing through an annulus region between a casing string in the wellbore and a reservoir formation. At a plurality of sensing nodes located along the casing string, information about the fluids is gathered by communicating with the RF MEMS tags placed in the fluids. The information about fluid locations along the casing gathered by the sensing nodes is communicated to a receiving device, and appropriate operation in relation to the wellbore is performed based on the communicated information.
