Imaging Tools are Much More Than Super-dipmeters

Abstract

Dipmeter tools were designed to provide a statistical dip analysis. They were essential to obtain a reliable structural interpretation inside the reservoir, but did not provide real geological description. On the contrary, the imaging tools developed during the last decades provide the way to perform real geological observation down hole. On ultrasonic or electrical images, fractures, texture, and sedimentary structures are directly observable, measurable, and interpretable as on outcrop. Because of this direct observation capability, it is possible to take advantage of the standard geological methods. For example, the computation of the actual structural dip is much more accurate than from basic dipmeter. Once the dip has been split into its structural and sedimentary components, it becomes possible to reconstruct structural or Sedimentary cross-section in the vicinity of the well, as it would be done from an outcrop.
