... is the missing piece of the puzzle to complement cement evaluation and leak detection solutions. In this work, we introduce an RFEC system utilizing high precision three-axis fluxgate magnetometer to address the challenge of defect localization beyond tubing. This paper is organized as follows: First, recent...

..., but the existing wellhead location was unable to be detected because the wells had been abandoned and cut off at the seabed level. Magnetometer was deployed to further investigate the existing wellhead location; the sensor was towed approximately about three (3) times water depth from the stern of the vessel...

... and not continuous as often considered in torque and drag calculations. Because of the punctual contact points, the partial differential equations that describe the drill-string motion contain discrete terms. The vibration sensor includes 3-axis accelerometers, gyro and magnetometers. The magnetometers give...

... Abstract The objective of this paper is to outline the advantages of using a gradiometer over a marine magnetometer for surveying the seafloor. Marine surveys conducted with a gradiometer will minimize external interference in the field allowing the interpreter to provide quick results...

... electromagnetic survey system with applying a super-sensitive magnetic sensor "SQUID" (Superconducting Quantum Interference Device). In this study, we have developed the component technologies of borehole SQUID magnetometer and powerful transmitter coil. The SQUID sensor performs in the temperature condition...

... Abstract Accurate orientation is required for both hole trajectory determination and for information gleaned from borehole images, acoustic waveforms and other azimuthally acquired data. Orientation quality depends on high quality acquisition of accelerometer and magnetometer information...

... ABSTRACT Seafloor observatories have been the important way to observe the ocean, but applying the magnetometers to it still remain technical problems. This paper presents a smart cheaper magnetometer which was designed as the sensor node for a small seafloor network for geomagnetic...

... Abstract The magnetic property of the drilling fluid is one of the substantial error sources for the determination of magnetic azimuth for wellbores. Both the weight material, cuttings, clay and other formation material plus metal filings from the tubular wear may distort the magnetometer...

Processing and analysis tools for the tensor data will be developed to reduce noise and to improve the detection thresholds achievable at larger sensor-target offsets than are currently possible with total field magnetometers. Initial stages of the project involve defining the nature...
