Abstract

A method of managing an inventory comprising downhole tools includes the steps of securing a passive RFID device to each downhole tool and utilizing an RFID signal generator/reader to read the passive RFID devices secured to the downhole tools as the downhole tools are introduced into a well. The output from the RFID signal generator/reader is utilized to prepare a listing of all of the downhole tools that have been directed into the well including the location of each of the downhole tools relative to each other. The RFID signal generator/reader is also employed to record the removal of the downhole tools from the well.

Claims

1. A method of managing an inventory comprising a predetermined quantity of downhole tools of the type utilized in the drilling and/or completion and/or production of an oil or gas well including the steps of:

providing a quantity of passive RFID devices at least equal in number to the number of downhole tools comprising the predetermined quantity thereof;

mounting at least one of the passive RFID devices on each of the downhole tools comprising the predetermined quantity thereof;

providing a well;

providing an RFID signal generator/reader;

positioning the RFID signal generator/reader at the entrance to the well;

directing selected downhole tools from the predetermined quantity thereof into the well; and

utilizing the RFID signal generator/reader to read the passive RFID devices secured to the downhole tools from the predetermined quantity thereof that are directed into the well.

2. The method according to claim 1 including the subsequent step of utilizing the RFID signal generator/reader to read the passive RFID devices secured to the downhole tools as they are removed from the well.

3. A method of managing a quantity of downhole tools of the type utilized in the drilling and/or completion and/or production of an oil or gas wells including the steps of:

providing a quantity of downhole tools;

providing a quantity of passive RFID devices at least equal in number to the number of downhole tools comprising the quantity thereof;

mounting at least one of the passive RFID devices on each of the downhole tools comprising the quantity thereof;

sequentially directing the downhole tools having the passive RFID devices mounted thereon into a well;

reading the passive RFID device secured to each of the downhole tools as the downhole tool is directed into the well; and

preparing a log comprising the listing of every downhole tool that has been directed into the well.

4. The method according to claim 3 including the additional step of:

providing an RFID signal generator/reader;

positioning the RFID signal generator/reader at the entrance to the well; and

utilizing the RFID signal generator/reader to read the passive RFID devices secured to the downhole tools as the downhole tools are directed into the well.

5. The method according to claim 4 including the additional step of:

utilizing the RFID signal generator/reader to read the passive RFID devices secured to the downhole tools as the downhole tools are removed from the well.
