Downhole Tools International Ltd (DTI) was established in 2009 to provide a range of quality products to the global oil and gas E&P market. Over the years, the company has built a trusted name for cost-competitiveness, reliability and exceptional service. Our range of products has expanded into the thousands and our inhouse manufacturing facilities support fast delivery and bespoke engineering.

In 2018, FrontRow Energy Technology Group established Pragma Well Technology, a production technology focused business to broaden the Group’s capabilities. Pragma was principally focused on technology innovation and engineering to provide cutting-edge solutions to solve complex downhole challenges. The company aimed to advance industry efficiency and cost-reduction through new approaches to current challenges. The company achieved several industry firsts and as its influence grew, was keen to marry innovation with an expanded portfolio and further global reach.

In 2021 Pragma acquired DTI, adopting their name and brand, but enhancing the customer offering with new technology solutions. With a shared vision of innovation, quality and performance, the company has embraced strong growth and success, working with customers in every region around the world on some of the most complex downhole challenges.

DTI is now offering its robust, field-proven solutions and exceptional engineering capability to other markets to support the global transition towards a more sustainable energy mix. Most of DTI’s downhole tools are suitable for cross-sector well applications, from oil and gas E&P and natural gas storage, to CCUS, hydrogen storage and geothermal production.

We are incredibly excited for the future and to be able to add the next chapter of achievements to our expanding innovation timeline.
