“…Although the vibrational method was introduced previously, because of the lack of an efficient transducer the method was not popular. Nowadays, piezoelectric ceramic technology has become more advanced, so the method of acoustic telemetry is beginning to gain commercial popularity (Haddad et al 2010;Dias et al 2014;Kreuzer et al 2014). In acoustic telemetry, the medium of pressure wave transmission is the solid steel pipe rather than viscous liquid as in MPT, so it has less attenuating factors.…”

Drilling for exploration and mineral extraction purposes is generally an invisible process, that is, there is a lack of real-time information available from the tool head. The borehole mining and oil-gas drilling industries both face tremendous challenges because of this invisibility. Lack of data has impacts on extraction quantity and quality, process efficiencies, and is a major factor in overall program costs. This is why a communication method between the drill head and the surface has been under research. Different communication methods have enabled industries to establish more control over the drill bit. Low data transmission rate is one of the most concerning drawbacks of existing communication methods. Acoustic, also known as vibrational telemetry, is the most recent method used in transferring data through drill pipe at the highest data transmission rate. The proper use of acoustic tools and communication schemes will successfully establish a fast data transmission rate and is expected to become a popular method. This paper will introduce a simulation model for transmission of data through drill pipes and will extrapolate a practical case of a large number of pipes that is usually used in oil-gas extraction. It will also demonstrate an experimental setup of a new acoustic transducer.

“…The vibrational method and theories have been known from the beginning of the MWD, but because of the lack of an efficient transducer, the method did not flourish. Currently, because of advancements in piezoelectric ceramic technology, the method has resurfaced and is beginning to gain commercial popularity [6][7][8][9].…”

In borehole mining and oil and gas drilling, the drilling process is invisible from the surface, which is why a two-way communication method between the drill head and the surface is a must. The popular industrial instrumentation technique, widely known as measurement while drilling (MWD), has enabled industries to save costly employee hours and gain more control over the drill bit direction. There are four major methods used throughout history, where the mud pulse telemetry technique has become the state of the art because of its simplicity and convenience. However, like other methods, it has a major drawback of having a slow data transmission rate. Moreover, other methods have different issues which include large attenuation of the data that is transferred through drill pipes. Acoustic telemetry is the most recent method of transferring data through a solid medium, a technique using continuous wave propagation of forces in the wall of the pipe. A proper use of this new method is expected to become popular in the mining and oil-gas industries because of its faster data transmission rate and ability to ignore most attenuating parameters. This method is still in its optimization stage, and the use of a convenient tool to match the transducer with the parameters of the drill pipe and surroundings is still a challenge to overcome. This paper will propose a simulation model to simulate the transmission of data through drill pipes, and will show experimental results of such arrangement justifying the opportunities ahead in this field.

Vibrational Data Communication Tools and Methods for Mining and Oil and Gas Extraction

Summary For the purpose of exploration and extraction, the drilling process in the mining and oil and gas industries is very complicated because of the obvious invisibility of the operation of the drill bit. Acoustic/vibrational telemetry has been of keen interest because it is so far the only method that allows a high data transfer rate as well as less data loss, over other methods. The method certainly depends on the use of the right communication tools and efficient communication schemes to achieve the highest data transfer rate. Although the acoustic method provides a very high data transmission rate, it also has its limitations. However, limitations can be overcome through certain approaches and the use of technologies. The proper use of a communication device with the steel pipe is the most important factor to consider so that the transducer works as the right actuator for the pipeline. The type of sensor that is used to pick up the data also plays a major role because signals are most likely to attenuate, and a sensitive sensor is necessary to collect these attenuated signals. This research demonstrates the use of a transducer as a communication device and oil and gas pipe as the medium of data transmission. The transducer can be used both as an actuator driver and as a receiver sensor. A new piezoelectric transducer was manufactured for this research, which was used with a test setup of a total 184 ft length of six oil and gas pipes. The test setup performed well and data were sent through this setup successfully. A communication scheme is developed using novel theories to achieve the highest data transfer rate. The scheme is tested with the transfer function data obtained from the experimental system. The communication scheme developed outputs a signal, which is a type of binary phase-shift keying signal data along with an equalizer filter. Then the signals developed from the scheme are used in the actual experimental setup to test the speed of the transmission and bit error rate (BER). For the six oil and gas pipes setup, the scheme provides a data transmission of 153 bits/sec (bps) with zero error percentage, which is high enough to use in any oil and gas industry.
