... ABSTRACT I present two examples of microseismicity in the Midland basin where the source mechanism nodal planes indicate shearing is persistently aligned with the hydraulic fracture or, alternatively, orthogonal to the hydraulic fracture. I consider arguments for both possible solutions where...

Depending on the stress regime, dip-slip events can be explained by slip on horizontal fault planes in strike-slip environments and by slip on vertical fault planes in normal faulting domains. Due to local rotations of the stress field, these fault...

An event’s focal plane amplitude nulls can be determined from the recorded data automatically and typically lie within a narrow band of angular range. We use elasto...

... ABSTRACT During hydraulic fracturing, focal mechanisms of microseismic events often exhibit a near-horizontal nodal plane. Previous studies have pointed out that this type of focal mechanism is consistent with stick-slip behavior on relatively weak bedding planes, adjacent to expanding...

..., and the relationship between microseismicity and hydraulic / natural fractures. We show that stress inversion with event focal mechanisms could help us better interpret microseismicity by identifying slip direction, and the true fault plane on which it occurs.
