Management

Services

We create custom management plans to help you adapt to the changes that occur within geothermal resources under production.

Adequate resource monitoring is critical to resource management, particularly during the first several years of resource operation. This helps us to determine when additional wells are needed, the optimal production and injection strategy, and if the geothermal resource can create additional electricity.

We provide a range of services to ensure sustainable utilization of geothermal resources:

Precision Gravity Monitoring

Microgravity is used to monitor the density changes that occur in the sub-surface during operations. These density changes are due mostly to the changes in water and steam content in the reservoir. This information can inform a resource conceptual and numerical models, resource management and where to place additional production and injection wells. We can provide survey planning, data processing and interpretation of precision gravity surveys.

Microseismic Monitoring

Microseismic events are small earth tremors caused by the injection of fluid back into the reservoir or by natural processes. Monitoring of this activity can be used to understand how injection fluid flows through a reservoir.

We can provide a complete, customized microseismic monitoring program covering network design, equipment purchase and installation, data processing and interpretation. We ensure accurate seismic event locations and a well-designed seismometer network so we can gain the most value out of microseismic monitoring. We can also perform tomographic inversion for seismic velocity and attenuation, probabilistic focal mechanisms and stress inversions to maximise the information that is extracted from microseismic monitoring.

Production + Injection Strategy

By using conceptual and numerical models, a production and injection strategy can be developed and tested. These include information about the large-scale permeability structure of the reservoir; where the fluid flows under production and injection, the depth of wells, well spacing and the distance and location of injection relative to production.

Conceptual Models

The development of a resource is based on all available relevant resource data. These inform the basis to build a numerical model that can be used to determine electrical generating capacity and to test different production and injection strategies.

Consent + Regulatory Compliance (NZ)

To explore and develop a geothermal asset there are several legal processes that need to be followed. These include New Zealand consent annual, quarterly reporting, and resource consent applications. We can assist with consent reporting and application requirements.
