Drilling Tool Rentals & Sales in Anadarko (SCOOP/STACK)

Drilling activity in the Anadarko

The Anadarko Basin of western and central Oklahoma is one of the deepest sedimentary basins in the United States, hosting the SCOOP (South Central Oklahoma Oil Province) and STACK (Sooner Trend, Anadarko, Canadian and Kingfisher counties) plays. Their defining feature is stacked pay — multiple productive intervals, including the Woodford and Meramec, layered so operators can develop several targets from shared infrastructure. Portions of the basin reach significant depths with correspondingly high pressures.

Development is led by operators including Devon Energy, Continental Resources and Ovintiv, combining horizontal drilling with multi-zone completions. The mix of stacked targets and deep high-pressure sections makes well design and tubular selection more demanding than in shallower plays, and places a premium on inspected, correctly rated equipment.

What that means for the drill string

Anadarko wells rely on 5” and 5½” S-135 drill pipe as the workhorse, but the deeper, higher-pressure targets raise the importance of torque and tension capacity, connection integrity and correct material grades. Strings run with heavy-weight drill pipe and non-magnetic drill collars for the directional BHA, and pressure-control equipment matters for the high-pressure intervals. Rigorous inspection and traceability support safe execution at depth.

• Drill pipe — 5” and 5½” S-135 for deep laterals
• Heavy-weight drill pipe — for the transition zone
• Drill collars — including non-magnetic for the directional BHA
• Pressure control — for deep, high-pressure intervals

Logistics and standards

Anadarko operations run in imperial units with tubulars inspected to API manufacturing specifications and DS-1 used-pipe categories, under Oklahoma state oversight. Given the deep, high-pressure targets, Drillstrings emphasizes tight-tolerance inspection, correct grades and full traceability, working through regional partners to stage and truck tools to the rig.
