Downhole Tubular Rentals
With strategic stocking locations worldwide and unmatched logistics, Workstrings® has the industry's largest inventory of rental landing strings.
From Drill String to Landing String, We’re Your First String
Our robust rental portfolio of downhole tubulars and drilling tools is matched by our uncommon flexibility and dedication.
Drill Pipe
Because drill pipe is the primary component of any drill string, it’s critical that it optimally transmits torque and power from the rotary table to the bit. We offer 2-3/8” to 7-5/8” in various wall thicknesses and grades (105 ksi to 165 ksi).
Landing Strings
When regular drill pipe lacks sufficient tensile strength, we meet the challenge with the industry’s largest landing-string inventory. Manufactured from high-grade steel, our heavy-wall drill pipe (0.500” to greater than 1") is commonly used to land, heavy subsea casing strings.
Heavy Weight Drill Pipe (HWDP)
Used as a transition between stiff drill collars and limber drill pipe, our HWDP helps reduce pipe fatigue with 2-3 times the wall thickness. We offer a full inventory with connections to match your drill pipe connections from 3-1/2” to 6-5/8” in conventional, spiral, and tri-spiral designs.
Drill Collars
Featuring pin and box connection threads machined directly into the body wall, our Drill Collars are available in 2-1/2” to 9-1/2” sizes. To reduce the tendency to differentially stick as they apply weight to the bit, spiral grooves may be cut into the collar.
Tubing
Featuring pressure-rated connections, our Tubing is designed for a wide variety of different production scenarios including workover, completion, cleanout, cementing, and re-entry and drilling through cement. We offer from 2-3/8” to 5” sizes.
Completion and Intervention Tubulars
Designed for subsea tubing landing strings, flowback/test strings, and intervention strings, these tubulars are proven in open water applications with a gas-tight metal-to-metal seal for well integrity. Featuring a rotary-shouldered connection, they enable fast make-up, compatibility with conventional drill pipe handling equipment, and durability for multiple make-and-break cycles.
WorkTech™ Joints
WorkTech™ Joints were developed as a slick joint across the annular BOP for frack tool movement. The WorkTech™ connection was designed with a metal-to-metal seal connection that can withstand the pressures of the fracking operation and be compatible with the completion string.
