Abstract

Identification and tracking of hollow pipes at a site where the hollow pipes are to be stored or interconnected, such as an oil drilling site where the aforesaid hollow pipes are to be connected and the drillstring of pipes is to be inserted into a drilled hole on solid ground or under a deepsea drilling platform is achieved. Each hollow pipe is provided with a low frequency radio frequency identification (RFID) tag attached to the pipe'"'"'s outer surface. The RFID tag is operable at a low radio frequency not exceeding 1.0 megahertz and may be disposed within a recess in the pipe'"'"'s outer surface. A tracking system provides communication be the tags and a reader.

Claims

1. A trackable pipe comprising:

a) a hollow pipe comprising a wall portion having an outer surface;

b) a low frequency radio frequency identification (RFID) tag attached to said hollow pipe at said outer surface, said RFID tag being operable at a low radio frequency not exceeding 1.0 megahertz, said RFID tag comprising;

i) a tag transceiver operable to transmit and receive data signals at said low radio frequency not exceeding 1.0 megahertz;

ii) a tag communication antenna operatively connected to the tag transceiver;

iii) a tag data storage device operable to store data comprising identification data for identifying said object;

iv) a tag data processor operable to process data received from said tag transceiver and said tag data storage device and to send data to cause said tag transceiver to emit an identification signal based upon said identification data stored in said tag data storage device; and

v) a tag energy source for activating said tag transceiver and said tag data processor.

2. The trackable pipe as set forth in claim 1, said wall portion comprising a recess that opens into said outer surface, said RFID tag being disposed within said recess of each hollow pipe.
