“…Since their inception in the 1930s, FGMs have been used to measure magnetic fields in a wide range of applications [ 22 , 23 , 24 ] and have recently progressed to solid-state sensors with the advancements made in micro/nanofabrication technology. Thorough reviews of FGMs can be found in [ 1 , 2 , 25 , 26 , 27 ].…”

In this paper we present a review of the application of two types of magnetic sensors—fluxgate magnetometers and nuclear magnetic resonance (NMR) sensors—in the oil/gas industry. These magnetic sensors play a critical role in drilling wells safely, accurately and efficiently into a target reservoir zone by providing directional data of the well and acquiring information about the surrounding geological formations. Research into magnetic sensors for oil/gas drilling has not been explored by researchers to the same extent as other applications, such as biomedical, magnetic storage and automotive/aerospace applications. Therefore, this paper aims to serve as an opportunity for researchers to truly understand how magnetic sensors can be used in a downhole environment and to provide fertile ground for research and development in this area. A look ahead, discussing other magnetic sensor technologies that can potentially be used in the oil/gas industry is presented, and what is still needed in order deploy them in the field is also addressed.

“…In a typical fluxgate sensor, the coils are directly wound around a magnetic core for operation [6,7]. Solenoid-shaped coils cause complications in manufacturing, and the complex structures of the coils and core make it difficult to integrate them with the working circuit.…”

In this study, a two-axis fluxgate sensor based on PCB technology is presented. The sensor consists of multiple layers and uses silver ink to form vias. Each layer of the coil is designed in a rectangular spiral shape and a cross-shaped magnetic core is utilized to achieve two-axis sensing. The fabricated sensor consists of one excitation coil layer, three sensing coil layers and a magnetic core with dimensions of 50 mm × 50 mm. With a sinusoidal excitation signal at a frequency of 50 kHz and a current of 500 mA, the proposed sensor has a sensitivity of 2496 V T−1 at 80 µT. It can also sense vector magnetic fields in a plane by comparing the two-axis signals.

“…Consequently this paper proposes a scheme to develop a measuring system for well logging attitude by using a MEMS three-axis accelerometer and a three-axis fluxgate sensor which has small size [7], light weight, low power consumption and no gyroscope. As there are various sensor errors which affect the accuracy of the calculated angle [8–11], it is particularly important to find a way to effectively reduce these errors.…”

This paper proposes an approach for measuring the azimuth angle and tilt angle of underground drilling tools with a MEMS three-axis accelerometer and a three-axis fluxgate sensor. A mathematical model of well logging attitude angle is deduced based on combining space coordinate transformations and algebraic equations. In addition, a system implementation plan of the inclinometer is given in this paper, which features low cost, small volume and integration. Aiming at the sensor and assembly errors, this paper analyses the sources of errors, and establishes two mathematical models of errors and calculates related parameters to achieve sensor calibration. The results show that this scheme can obtain a stable and high precision azimuth angle and tilt angle of drilling tools, with the deviation of the former less than ±1.4° and the deviation of the latter less than ±0.1°.
