Journal: AAPG Bulletin
Published: 01 December 2015
AAPG Bulletin (2015) 99 (12): 2203–2219.
... considerable attention from the fracture characterization research community because of the importance of fractures to the prediction of fluid flow. One of the most common methods for rapidly analyzing fracture features is the scanline technique, which provides an estimate of fracture density and frequency...
