Oilfield vector clipart. He is some silhouettes and symbols related to oil and gas well drilling industry: drilling machinery, oilfield equipment, off shore oil rig, crane, derrick, energy, pipe, plant, platform, oilfield towers and buildings, oil barrel, icons of oil drop and other symbols of resource’s mining.
All silhouettes provided in vector format. It’s very elementary to edit any vector illustration: replace shapes, rotate, change color, join with other shapes, change size. I myself prefer to use Illustrator CS (or higher), but you also can try to use your favorite drawing program for editing vector files, like, Photo Styler, Xara, Corel Draw, PMView, Flash.
