Abstract
The need to accurately locate pipelines and other cultural features is of paramount importance to the safety,<br>planning and quality of 3D seismic data.<br>With the current industry trend being to maximize production from known reserves, there is an increased practice<br>of shooting 3D seismic surveys over mature and previously abandoned oil and gas fields. In many instances, the<br>infrastructure in the abandoned, and even the active oil and gas fields is poorly documented, and hazard locations are inaccurate.<br>This lack of knowledge about the location of pipelines, well heads and other oil field infrastructure poses a danger<br>to the seismic crews drilling shot holes within the boundaries of the oil field. It can also cause degradation of the<br>quality of the seismic data; gaps in the shot point positions, created by safety requirements to avoid areas of<br>uncertain pipeline location, result in poor, or zero, seismic fold coverage in the areas of most interest; the oil field itself.<br>The purpose of this paper is to present a new airborne technology for the detection and mapping of oil field<br>infrastructure, and to review how this technology, when used in conjunction with modern 3D seismic planning<br>software, can result in cost savings, enhanced safety and higher quality 3D seismic surveys.
