Major Operators Save $40 Million+ on Deepwater Exploration Wells

Landing String Solutions, LLC
Madisonville, LA:
Two Successful Implementations of Patented Landing String Buoyancy System Give New Options to Oil Companies

Groundbreaking but simple landing string buoyancy technology provides a new option for drillers and operators to enhance the rig’s hoisting capacity by up to 20%. This allows for longer casing runs, can eliminate tiebacks, results in larger wellbore designs, and enhances performance of rigs drilling in ultra-deepwater.

The technology is based on Archimedes’ principle and utilizes Trelleborg syntactic foam modules installed onto casing landing strings to produce upthrust. Custom designed non-metallic clamps are used to eliminate the concern for metal fasteners in the wellbore. The buoyancy system is assembled offline onshore, loaded in purpose-built baskets then shipped to the rig.

Benefits

• Up to 450,000 lbs. of weight reduction in the landing string depending on mud weight and water depth;
• The lower hook load reduces and possibly eliminates slip crushing;
• Provides additional safe working margin versus maximum allowable rig load limits;
• Enhance drilling rig capability to simplify complex well designs;
• Potential elimination of casing strings, liners and tiebacks allows for larger diameter completion design;
• Can be deployed in open water;
• $40 Million+ cost savings for fewer casing strings and/or tiebacks resulting in reduced rig days;
• Global availability.

Six available run slots for 2019 and one standby run slot available in 2018. For more information please contact Chris von Eberstein via email at chris@landingstringsolutions.com or telephone at 844-522-7900.
