Tubular Services
Everything Your Workstring Needs, From One Supplier.
DTI supplies premium drill pipe, heavy-weight drill pipe and tubing for drilling, workover and completion operations, with the handling tools and API blowout preventers that go with them. Pipe comes from qualified suppliers with premium connection licenses and is inspected before it reaches your location.
Challenge
Every foot of the well hangs on the workstring. When pipe, handling tools and pressure control arrive from different suppliers on different schedules, the gaps show up on the rig floor.
Here's where tubular support matters most.
Pipe Integrity
Worn tool joints, wall loss and damaged threads lead to washouts and twist-offs, and a twist-off turns into a fishing job.
Mismatched Handling Tools
Slips, elevators, tongs and drifts have to match the pipe and connection on location. One wrong size can stop a trip.
Pressure Control Readiness
BOPs and accumulators have to be rated for the job and supported on site, especially in workover, hydraulic workover and snubbing operations.
Capabilities
One Order for the Complete String
Tubular Services puts pipe, handling tools and pressure control on a single order, backed by the same inspection, logistics and COMPASS ordering that support our directional rental fleet.
Premium Pipe, Inspected
Drill pipe and heavy-weight drill pipe in API and proprietary double-shoulder high-torque connections, inspected to TH Hill DS-1 and API RP7G-2 by certified inspectors.
Handling Tools That Match
Rotary slips, elevators, manual tongs, stabbing guides, safety clamps and drifts sized for the pipe we supply, available on the same order.
Pressure Control, Supported
API blowout preventers rated to 5M, 10M and 15M psi, with accumulators, chokes, manifolds and valves, and BOP technicians available on site around the clock.
