Pulsed power is particularly effective at removing scale – including the most challenging scale types, such as BaSO4 – and at reaching areas other methods can’t. The treatment can be deployed on precise intervals of the well.
Applications of pulsed power in well intervention broadly fall into two categories – stimulation and equipment cleaning – with compelling use cases along the well lifecycle, from post-completion through to decommissioning. It has also been used successfully to boost the effectiveness of other treatments like acid.
The technology’s small footprint, ease of deployment and relatively short treatment time suit scenarios where intervention would otherwise be uneconomical. And because it cleans more deeply, results typically last much longer.
