Radio-frequency identification (RFID) is the use of a wireless non-contact system that uses radio-frequency electromagnetic fields to transfer data from an RFID tag attached to an object, for the purposes of automatic identification and tracking. Some RFID tags require no battery and are powered by the electromagnetic fields used to read them. Others use a local power source and emit radio waves (electromagnetic radiation at radio frequencies). The RFID tag contains electronically stored information which can be read from up to several feet away. Unlike a bar code, the RFID tag may be embedded in the tracked object or otherwise obscured.
RFID tags are used in many industries. For example, in the oil and gas industry, RFID tags are used to track assets used in downhole operations. However, conventional RFID tags are not designed for operations in harsh subterranean environments. Furthermore, conventional asset tracking methods may not be suitable for use in subterranean environments. Additionally, assets used in downhole operations may not be suitable for integration with certain RFID tags. Such assets may not have the proper thickness, the proper dimensions, or a large enough section for receiving an RFID tag suitable for subterranean environments.
There is a need for an improved system and method for integrating an RFID tag suitable for subterranean environments with assets used in downhole operations.
It is an object of the present invention to provide an improved system and method for integrating an RFID tag suitable for subterranean environments with assets used in downhole operations. More particularly, the present invention allows for mounting RFID tags to assets used in downhole operations with a variety of dimensions and thicknesses.
In one embodiment, the present disclosure provides an RFID connection sleeve assembly comprising an RFID tag, a sleeve, and a tool, wherein the RFID tag is mounted to the sleeve and wherein the sleeve is secured to the tool. The RFID tag may be mounted to the sleeve by means of a cavity formed in the sleeve. A cavity may be formed by means of milling a slot for receiving the RFID tag. The RFID tag and/or cavity may be constructed in such a manner as to allow the tag to be mounted in the cavity by means of physical or mechanical forces.
In another embodiment, the RFID tag may be mounted to the sleeve by means of an adhesive and/or an overlying protective coating, such as a thermoplastic material or epoxy material. In yet another embodiment, an adhesive and/or an overlying protective coating may be used to secure an RFID tag in a cavity formed in the sleeve.
In another embodiment, the sleeve may be secured to the tool by means of a threaded connection. One or more threads may be located on the outside of the tool. The one or more threads may be integrated into a tool by means of a milling process. The sleeve may have one or more threads located on the inside of the sleeve that are configured to connect the sleeve to the tool by means of a threaded connection.
In another embodiment, the sleeve may be secured to the tool by means of physical and/or mechanical forces. As an example, the sleeve and tool may be connected through one or more interlocking grooves. In one embodiment, one or more grooves may be integrated into the outside surface of the tool, such as through a milling process. The sleeve may comprise one or more connection components that are configured to mate with the one or more grooves and form an interlocking connection. In another embodiment, one or more grooves may be integrated into the inside surface of the sleeve, such as through a milling process. The tool may comprise one or more connection components that are configured to mate with the one or more grooves and form an interlocking connection.
In another embodiment, the sleeve may be secured to the tool by means of an adhesive. The adhesive may be applied to the outside of the tool and/or the inside of the sleeve.
In another embodiment, the sleeve may be secured to the tool by means of one or more external screws. In one embodiment, the one or more screws may be configured in a radial direction relative to the center of the tool and pass through both the sleeve and the surface of the tool. In another embodiment, the one or more screws may be configured in a tangential direction relative to the surface of the sleeve and/or the surface of the tool. The one or more screws may by connected to a clamping mechanism that secures the sleeve to the tool through physical or mechanical forces.

The present invention relates to combining RFID tags suitable for use in subterranean environments with assets used in downhole operations. Some assets used in downhole operations may not be readily suitable for integration with certain RFID tags in a manner suitable for use in a downhole environment.
