GCDT Profile

GCDT designs and manufactures downhole equipment for the oil and gas industry. Our products are installed in oil and gas wells around the world. These products are integral components in the downhole systems that provide downhole control, injection, flow assurance and monitoring. Our customers are predominantly oil field service companies but also include oil and gas producers.

The company was formed in 1999 in Houston, Texas, originally manufacturing downhole cable. Our management team, which has a strong oilfield background, has grown the company to being a market leader in our field by providing a diverse range of products to a global customer base.

Prysmian Group, world leader in the energy and telecom cable systems industry, acquired GCDT in 2015. Prysmian Group’s acquisition provides a new chapter for GCDT with many positives that include: a larger manufacturing capacity, a secure supply chain from an industrial partner, an enhanced ability to develop products, and access to a truly global footprint.
