自主无人机(无人机)技术的最新进展，以及总场磁强计小型化的成功努力，为测试用于广域高分辨率磁力测量的低成本无人机安装系统提供了独特的机会。现代无人机平台能够在低空飞行并收集密集的航空测量，再加上灵敏和紧凑的仪器，使以前只能在地面磁强计测量中才能识别的人为目标得以识别。我们介绍了一项概念验证研究的结果，重点是开发和现场测试基于无人机的磁强计系统，以检测和识别纽约州历史上油气勘探和开发地区的废弃和未标记的油气井。我们的结果表明，与直井金属套管有关的磁异常在地表和高达50m的地面上都明显高于背景水平。我们确定，在以最高信噪比记录磁数据时，最佳探测高度为40m，以避免任何树冠干扰。这一方法使快速检测和识别无标记油井成为可能，进而使这些地区今后的可持续发展成为可能。
Recent advances in autonomous unmanned aerial vehicle (UAV) technology, along with successful efforts to miniaturize total field magnetometers, offer a unique opportunity to test low-cost UAV-mounted systems for wide-area high-resolution magnetic surveys. Modern UAV platforms capable of flying at low altitudes and collecting dense aerial surveys, coupled with sensitive and compact instruments, allow identification of anthropogenic targets previously identifiable only in ground magnetometer surveys. We present results of a proof-of-concept study focused on developing and field testing a UAV-based magnetometer system to detect and identify abandoned and unmarked oil and gas wells in an area of historical hydrocarbon exploration and development in New York state. Our results indicate that magnetic anomalies associated with metal casing of vertical wells are pronounced considerably above background levels both at the surface and up to 50 m above-ground elevation. We determine that a detection altitude of 40 m is optimal to avoid any canopy interference while recording magnetic data at the highest signal-to-noise ratio. This methodology makes rapid detection and identification of unmarked wells possible and, in turn, allows for future sustainable development of these areas.
