Understanding what’s beneath the surface is critical to making geothermal energy economic. Reservoir characterization helps determine rock and fluid properties of the subsurface to give insight into the geological complexity.

SLB reservoir performance experts provide a series of measurements—even in temperatures of up to 500 degF—to identify economically productive reservoirs and inform your decision making.

In geothermal projects, regulators may require continuous monitoring of the project over its lifespan. To do this, we utilize either permanent fiber or wireline-deployed fiber, depending on your project. SLB’s fiber-optic borehole seismic solution enables the real-time recording and processing of microseismic events, efficiently transmitting essential data to operators without the need for transmitting massive amounts (terabytes) of data.

Assessing the performance of injection wells is achievable through injection flow profiling solutions and standard or high-temperature production logging tools.

With wireline formation testing, we can assess pressure dynamics within the reservoir. This helps identify factors that may contribute to heightened boiling points and improved fluid transport, consequently facilitating more effective energy conversion. The evaluation of the initial reservoir pressure and subsequent modeling plays a pivotal role in this process.
