... in inefficient refracturing due to the high leak-off or fracture reorientation. Thus, the volume and timing of fluid injection is important for the effectiveness of refracturing. To properly predict the geometries of re-fractured hydraulic fracture, it is necessary to consider both the stresses and pore pressure...

ABSTRACT The water hammer signatures, which can be observed after pump shutdown at the end of a hydraulic fracture treatment, have proven to contain useful information about the geometry of generated hydraulic fractures. This paper presents a novel hydraulic fracture diagnostics approach using...
