Abstract

With increasing costs of wells it is becoming increasingly necessary to perform different drilling/completion tasks in single trip. Radio Frequency Identification (RFID) technology that is gaining popularity in the recent times can be used as a means to mill a lateral path as well as drill using PDC drill bit to desired depth in single trip.

Title: Single trip mill and drill out of multilateral well using RFID technology

Abstract: With increasing costs of wells it is becoming increasingly necessary to perform different drilling/completion tasks in single trip. Radio Frequency Identification (RFID) technology that is gaining popularity in the recent times can be used as a means to mill a lateral path as well as drill using PDC drill bit to desired depth in single trip.

Discussion: Radio Frequency Identification (RFID) is a wireless data-capture technology that does not require line-of-sight and has considerably longer read ranges. In addition, this next-generation data capture technology has the ability to reprogram and extends its identification as it progresses, enabling information to be encoded to the product identifier at any point in its lifecycle. The wireless ability of RFID, its extended read range, and its capability to modify its identification, has opened the technology to a range of application areas in the oil and gas industry. (1)

An RFID system uses tags attached to physical objects to be identified. The tag includes a small RF transmitter and receiver, as well as a circuit chip to store the encoded data. An RFID reader, which is a two way radio transmitter-receiver, transmits an encoded radio signal to interrogate the tag. The tag receives the message and responds with its identification information.

The RFID technology is widely used in many industries such as retail, medical, transportation and packaging, but new technologies now allow RFID tags to survive the harsh environments of oilfield operations. Latest improvements in RFID technology allows them to withstand extreme temperatures, pressures, corrosion, abrasives and vibrations, as well as be readable through drilling mud and dirt. (3),

Several patents have been issued additional patent applications have been filed regarding oil field applications of RFID. One area where the oil field uses of RFID does not appear to have been covered by patent coverage is in the milling/drilling of multilateral wells. For a multilateral...
