Experiments on Stoneley Wave Propagation in a Borehole Intersected by a Finite Horizontal Fracture

P143 Experiments on Stoneley wave propagation in a borehole intersected by a finite horizontal fracture HENRY F. FOKKEMA J.T. de PATER C.J. TU Delft Applied Earth Sciences University Mijnbouwstraat 120 2628RX Delft The Netherlands Summary The propagation of the Stoneley waves in a fluid-filled borehole intersected by a horizontal fracture with a finite radial extent is investigated experimentally. By comparing the results of this experiment with those of an open horizontal fracture we can quantify the effect of the reflection of the fracture wave at the fracture tip on the borehole wave propagation for a same range of parameters (fracture
