“…Cable-free land seismic acquisition is discussed in several research articles [10,11,25,28,[39][40][41], with deep insight into land seismic surveys and the requirements necessary to achieve optimum results in such a survey. Many others discussed wireless geophone network architectures and technologies for large-scale land seismic survey [8,9,12,29,30,42].The most recently introduced real-time wireless system aiming at large seismic channel count is the RT3 system developed by "Wireless Seismic Inc." (Stafford, TX, USA) in 2017 [28]. The system comprises of a recording unit called "mote", a ground relay unit (GRU) that serves as the gateway, and a CCU called the central recording system (CRS) that supports over 250,000 seismic channels.…”

Seismic data acquisition in oil and gas exploration employs a large-scale network of geophone sensors deployed in thousands across a survey field. A central control unit acquires and processes measured data from geophones to come up with an image of the earth’s subterranean structure to locate oil and gas traps. Conventional seismic acquisition systems rely on cables to connect each sensor. Although cable-based systems are reliable, the sheer amount of cable required is tremendous, causing complications in survey logistics as well as survey downtime. The need for a cable-free seismic data acquisition system has attracted much attention from contractors, exploration companies, and researchers to lay out the enabling wireless technology and architecture in seismic explorations. This paper gives a general overview of land seismic data acquisition and also presents a current and retrospective review of the state-of-the-art wireless seismic data acquisition systems. Furthermore, a simulation-based performance evaluation of real-time, small-scale wireless geophone subnetwork is carried out using the IEEE 802.11 g technology based on the concept of seismic data acquisition during the geophone listen or recording period. In addition, we investigate an optimal number of seismic samples that could be sent by each geophone during this period.

“…where X * Y denotes a blockwise product of X and each of the sub-blocks of Y, and d denotes the ratio of the FIM element J yy in the 2-hop case to the 1-hop case, assuming that the path loss arises from free-space propagation and atmospheric absorption. The atmospheric absorption loss is expressed as L −∆ 0 , where L 0 = 10 0.0017 at f c = 60 GHz [9]. An approximation is made by considering only the product of the (G/2) th submatrices of the inverse of each of the tridiagonal matrices, since this product is the dominant contributor to the value of C G/2 .…”

“…The value of P tx is set to −8 dBm in both cases since UWB systems are limited by a maximum power spectral density of −41.3 dBm/MHz. The two-ray propagation model is considered in both scenarios, since low antenna heights of 0.1-0.2 m are typically perceived in geophone networks for logistical purposes and to counter the effect of high wind speeds [9]. Hence, the PEB is averaged over 1000 Monte Carlo iterations, with the antenna heights and the orientation angles being uniformly distributed in the intervals [0.1 m, 0.2 m] and [0, 2π) respectively.…”

In applications such as seismic acquisition, the position information of sensor nodes, that are deployed in a linear topology, is desired with sub-meter accuracy in the presence of a limited number of anchor nodes. This can be achieved with antenna arrays via mm-wave cooperative localization, whose performance limits are derived in this letter. The number of anchor nodes is seen to have a stronger impact than the number of antenna elements in the anchor nodes. Succinct closed-form expressions for the position error bound are also obtained for 1-hop and 2-hop cooperative localization, where sub-meter accuracy is perceived over several hundred nodes.

“…Nonetheless, it is worth noting that there are several other network designs adopting the WSN concept for seismic acquisition applications focusing on other aspects of the system, such as the network architecture, the technology used for sensing, and the ADC bit resolution [4]- [9]. Moreover, there has been significant recent progress on the design and implementation of WSNs for passive seismic monitoring [16]- [18], which are smaller scale networks -compared to those deployed for active seismic surveys -targeted at a range of different applications, including volcano monitoring.…”

Wireless Geophone Sensing System for Real-Time Seismic Data Acquisition

et al. 2020

Active seismic surveys, for the exploration of oil and gas reservoirs, are conducted using a huge network of geophone sensors (>10,000) covering a very large area and interconnected using seismic cables. Such cables enable reliable operation and fast data transfer, but account for a major percentage of the survey cost and limit its flexibility. In this paper, a wireless seismic data acquisition system that provides real-time data transmission for active seismic surveys is designed and implemented. A system that comprises a smart wireless sensor node and a gateway unit is demonstrated as a proof-of-concept. The smart wireless node comprises a geophone sensor, a high-resolution data acquisition system and a smart reconfigurable wireless communication module. The data acquisition system includes an electronic circuit for amplification and filtering, a single-board computer and a 24-bit analog-to-digital converter (ADC). The wireless communication module comprises a 2.4 GHz radio frequency (RF) transceiver connected to a pattern reconfigurable antenna. A microcontroller is employed to reconfigure the Yagi-Uda antenna to scan its radiation pattern in different directions and focus the radiated power in the direction of the nearest gateway. This high-gain directional antenna would allow communication between the sensor node and the gateway over a longer distance as compared with the monopole antenna conventionally employed in commercial wireless seismic systems. The proposed system, employing a reconfigurable antenna in the sensor node, has been implemented and tested and was able to successfully capture seismic data from the geophone sensor and transmit it wirelessly in real-time to the gateway unit, achieving a notable 25% enhancement in the communication range between the sensor node and the gateway. This communication range enhancement results in a significant 56% enhancement in the gateway's communication area coverage, when compared to similar systems that use conventional monopole antennas in their sensor nodes.
