Similarities between Oil/Gas Technology and Brain Surgery
- Wellbore Drilling Versus Deep Brain Stimuli (DBS)
Job objectives
- Wellbore Drilling
- To safely drill a hole from the surface (or the sea bottom) to a predefined underground target for exploration- or production purposes
- DBS-operation (Deep Brain Stimulation)
- To safely drill two holes through the scull and to push electrodes toward targets deep in the core of the brain to improve the life quality of patients with Parkinson’s etc.
Targets
- Wellbore drilling
- DBS
Target size - Distance
- Wellbore drilling
- Wellbore length – 1 to 15 km (Typical 2 km)
- Typical target size
- Hz: 100m X 100m
- V: 1m (Average 67m)
- Relative difference
- For 2 km wellbores 1D; 67 : 2000
- DBS
- Penetration length – 8 to 12 cm (Typical 10 cm)
- Target size
- About the size of a piece of rice
- 6mm X 2mm X 1mm (Average 3mm)
- Relative difference
- For 10 cm penetration 1D; 0.3 : 10
Other Similarities
- Both tasks can be divided into three closely linked project/job phases
- Initial phase Establishing common references for explorations/underground drilling and for pre investigations/brain operation
- Drilling/operation phase
- Production/stimulation phase
- The principal project phases may even be divided into closely linked sub groups
- Most of these tasks are dangerous and may result in fatal accidents
- Especially if safety precautions are not in place or are neglected
