Strada, an innovative technology company, specialising in deep drilling, have released the following summary of the Lloyds Register Technology and Risk Assessment Report, which approved in principle the concept of their unique, patented, Fluid Hammer Operating System (FHOS). Further testing of the FHOS is currently underway, but in advance of its completion the Lloyds Register report gives an exciting insight into what this new technology will deliver.
In summary, the Lloyds Register assessment found that the goals and claims made of the FHOS technology could all be met or exceeded, specifically in relation to:
- Strada’s rigs being physically smaller than alternative rigs.
- Being capable of controlling the down-hole temperature by regulating the mud/water/air circulation.
- The capability of drilling in balanced underbalanced and overbalanced modes.
- Hard rock penetration rates - using percussion hammers are generally higher than 20 meters per hour in 200 MPa rock, such as granite and basalt.
- Reduced drill pipe wear.
- Longer drill bit life.
- Being capable of reducing drilling costs by up to 70% in comparison to existing technologies. These costs savings are derived from a reduced number of trips, quicker drilling and reduced mobilisation costs.
- Requiring crews of less than 5 required.
- Being capable of drilling over 6000m
