Onshore passive seismic acquisition and interpretation
We are a highly experienced hands-on consultancy team of geoscientists and project managers whose sole aim is to help and assist clients in achieving their exploration and development goals. We bring decades of experience from the onshore hydrocarbon and waste sectors, and more recently in the and CO₂ storage sector. We offer bespoke, tailored solutions to our clients who need our specialities to successfully acquire their sub-surface detail in the onshore domain. Historically, most of our onshore work has been done in Eurasia and European countries, but we can also offer practical solutions worldwide.
Our software and services have delivered innovative, client-driven solutions to the onshore E&P industry. Our dedication to continuous development ensures that our customers have access to the latest advances in onshore passive seismic acquisition technology. They can take advantage of our innovative interpretation software and passive seismic specialists to delineate hydrocarbons or manage assets within the onshore domain.
TenzorGEO data acquisition tools are already in use for onshore subsurface assessment. Our diverse offering comprising of passive seismic, data processing and subsurface insights through interpretive analysis provides unparalleled understanding of the subsurface and our clients’ operations. Our approach recognises the need for flexibility in technology coupled with cost-effective passive geophysical solutions to bring the confidence our clients expect when making investment decisions.

Onshore Acquisition
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.
