Fractures placed in the subsurface can be mapped remotely using surface mounted tiltmeters. Tiltmeters are highly sensitive instruments used to measure the minute ground surface deformations created during the fracturing process.
The direction and magnitude of micro ground surface deformations or “tilt” that is measured by tiltmeters is used to determine the dip angle, orientation, and extent of fractures in the subsurface. This information is input into an interactive 3D model to allow visualization of the fracture network in the treatment zone. The model presents the fractures or fracture network in a three dimensional form that provides viewing from any perspective and also allows cross-sectional views.
