Well intervention at half price

Resonator has reduced both energy and time spent in the execution of the operation in the well by 40 to 50 percent. One of the founders of the company, Svein Hestevik, says that this is just the tip of the iceberg of what the invention can contribute to in the oil industry.

– We have been able to significantly reduce the costs of removing mineral deposits. We estimate that the costs are halved compared with "milling", which is the current method that is used. Yet, this is just the beginning. Now we look at how our "cautious blow drill" can realize the development of new fields, which are currently not developed when one hits hard formations. Fields like Nordvarg and Victoria can be reconsidered for development if you use our electro-hydraulic hammer drill, says Hestevik.

Svein Hestevik’s Resonator is one of several other energy efficiency projects presented in the information brochure Energy efficiency and reduction of greenhouse gas emissions (PDF-3 632.9 KB)  made by the programs PETROMAKS 2 and DEMO 2000 in the Research Council of Norway.  

The deposits consist mainly of inorganic salts, the most common being calcium, barium and strontium sulfate. The salts attach to the inside of the well and may clog the well.

Pilot next

Many Norwegian fields struggle with deposits and could benefit from Resonators new technology. The next step will be to build a pilot of the tool and test the tool in the North Sea. Hestevik invites the industry to join the trial project.

– Both operators and suppliers will have a lot to gain from joining the work ahead. The oil and gas industry are requiring cost reductions, and the new technology that we have developed can be one of many solutions that they need, says Hestevik.

The demonstration project started in August 2012 and performance reports were to be presented during July 2015. The next step in the development of the technology will be to design and engineer a pilot tool that can be used in a producing well. The technology can also be developed for new, energy-efficient drilling in hard formations, and can also increase recovery in existing oil fields.

Broad support

Many see the potential of Resonators technology in a climate and environmental perspective. Both the oil companies and The Research Council of Norway see the opportunities in the project, and The Research Council of Norway has even provided financial support to the project through the petroleum programs PETROMAKS 2 and DEMO 2000. Resonators technology can reduce energy consumption in an operation by up to 50 percent, and this means that the climate benefits are good, especially considering that the majority of the power demand on the Norwegian shelf still is covered by old and inefficient gas turbines.

Resonator AS now welcomes the industry to take part in the results that the company has achieved in the project so far and invite representatives from the companies to its laboratory at NMBU (University of Ås), just outside Oslo, to join them for the road ahead.
