Onshore passive seismic acquisition and interpretation
Onshore Investigation Applications
Data processing and interpretation
Acquisition of microseismic data in an onshore environment is a far simpler task than that in offshore areas. Prior to the deployment of the sensor systems, a carefully modelled deployment gird is created. The deployment grid will be customised for each project depending on the depth of the target, the projected reservoir size and the objectives of the survey (exploration, appraisal or development and production).
Once a grid is established, sensors can be deployed. Depending on the goals of the study, 3-Component Geophones and/or hydrophones will be utilised. Each of the sensors will be positioned in the modelled observation point location. To ensure accuracy of recording and reduce the potential noise disturbances caused by surface sources (such as vehicles), the sensors are trenched below the surface. The equipment is connected with an umbilical or wirelessly depending on the project and location. Thereafter, the sensors will passively record the desired sound signals from the target area.
