Directed Technologies Drilling (DTD) is the nation`s leading contractor for horizontal environmental remediation systems.

Our company has focused on environmental applications of horizontal directional drilling since its inception in 1996. President Jim Doesburg was the founder of FlowMole Environmental Services, the early technology leader in the field.

Headquartered in Bellefonte, Pennsylvania with a west-coast office in Bremerton, Washington and an office in Mineral Wells, Texas, DTD has completed wells throughout the United States and at several European locations. DTD leads the industry in installed footage of completed, operational wells, and teamed with Mears/HDD to design and install the longest horizontal remediation wells in the world and the longest horizontal monitoring wells in the world.

DTD is committed to continual innovation and improvement of design and installation techniques for horizontal remediation systems.

Beyond Environmental Remediation
DTD also is the leading firm in the world for the design and installation of horizontal drains. We are routinely called to help design and install horizontal utility crossings. Our experiences in the complex and often challenging geology of Puget Sound have given us a technological edge over our competition. We have the experience and the equipment to tackle virtually any horizontal crossing problem.

Owned & Managed by Authorities in the Field
DTD is owned and managed by some of the world`s leading authorities in horizontal environmental drilling. Vermeer, the world`s largest manufacturer of directional drills, asked DTD to co-write their comprehensive manual on horizontal remediation wells. DTD also developed innovative well screen materials for horizontal wells.

Quality Performance & Innovation Every Day
Every DTD project is managed in the field by an experienced hands-on project manager to ensure that our systems are installed safely and meet project specifications. The success of our work depends on the proper design, installation, and operation of every horizontal well. Our experienced managers are intimately familiar with the installation process, from site logistics and health and safety to well development and system operation.

Our goal is total quality performance. We continually work to improve our equipment, installation methods, and system components to ensure that every system delivers the required performance. Because of our corporate relationships with other industry leaders, our ability to apply innovative approaches spans the breadth of system design, equipment specification, installation technique, and materials design and selection.
