From plan to plant
- Geological Study and Resource Confirmation
is the first step in an oil shale development project in order to map the oil shale deposit and to establish its characteristics and size. Samples are collected for further test work.
- Test Work
on a laboratory scale follows the geological survey. The chemical composition and physical properties of the oil shale are determined to evaluate whether the project is commercially viable.
Positive results of the test work lead to several further studies:
- A Mining Study
in several steps is needed to evaluate whether the resource can be mined economically and to determine the most suitable mining alternative.
- A Water Supply Study
evaluates existing conditions and assesses viable alternatives capable of delivering the water needed for the plant. Other utility studies evaluate the infrastructure of the location and its impact on the plant.
- Retort Testing
accompanied with Engineering Studies is done in parallel to find the best technical solution available for processing the specific material and to fix the design and the size of the plant.
- Oil Upgrade Testing
follows the oil production in the retort testing phase to allow assessment of the quality of the product and its marketability.
is started in the early stages of the project in order to acquire all the required environmental, construction and other permits by the time erection start is scheduled.
- Detailed Engineering
is done after the process engineering resulting in detailed information needed for building a shale oil plant.
- The Construction
phase lasts around three years. Oil shale mining is started in parallel so that enough oil shale can be produced by the time the plant is ready for operation.
brings the plant into steady operation.
