Casing Accessories<br />
<strong>TESCO</strong> makes available a full line of accessories that enhance CASING DRILLING® and casing running<br />
operations. Our leadership position in casing running technologies and global experience compels us<br />
to stay at the forefront of developing tools that streamline the process. We inventory a complete line of<br />
proprietary and conventional accessories around the world that simplify casing operations.<br />
Multi-Lobe Torque (MLT) Rings The <strong>TESCO</strong> MLT ring is a high performance,<br />
low cost OCTG connection enhancement that delivers premium performance to standard API<br />
Casing and Tubing. MLT rings fit standard API “off the shelf” casing and tubing extending<br />
the utility of operator pipe inventories. They are particularly effective when used on problem<br />
wellbores with a top drive and CDS. Installation is fast and easy and can be done at wellsite,<br />
pipe yard or mill. MLT rings are compatible with full API make-up tolerances through<br />
a unique gauging system and a selection of ring heights specific to the size and weight of the<br />
tubing or casing.<br />
Casing Running & Reaming Tool - Warthog <strong>TESCO</strong>’s Casing Running and Reaming<br />
Tool (CRRT), or Warthog, helps get your casing to TD despite compromising hole conditions such as<br />
bridges, ledges, doglegs, sloughing formations and deviated holes. The Warthog combines hydraulic<br />
and mechanical energy to break through downhole obstructions and a<br />
nosecone profile that cleans and circulates. Three spiral helix external<br />
blades help condition the hole and provide centralization for cementing.<br />
Pump Down Displacement Plug <strong>TESCO</strong>’s Pump Down Displacement Plug (PDDP) is a<br />
cementing accessory for use with CASING DRILLING® and Casing Running operations. The PDDP is<br />
pumped behind the cement job to displace the cement replacing conventional displacement plugs. It<br />
can be pumped down at normal pump rates and lands in the casing profile nipple. When landed, the<br />
solid plug holds backpressure preventing backflow and allows operators to continue with minimized<br />
risk of cement U-tubing.<br />
Hydro-Form Centralizers and Stabilizers Hydro-Form Centralizers<br />
are used in the casing string to facilitate improved cementing. Stabilizers are used<br />
at the bottom of a “drill-in” CASING DRILLING® string to stabilize the BHA (Bottom<br />
Hole Assembly). <strong>TESCO</strong>’s patented design and attachment method provides superior<br />
strength and rigidity capable of withstanding dynamic downhole loads while<br />
maintaining standoff under large side forces without crushing. <strong>TESCO</strong>’s Centralizers<br />
and Stabilizers provide positive centralization for cementing in vertical and deviated<br />
wells for both CASING DRILLING® and Casing Running applications. These accessories<br />
facilitate rotation of the casing string, a significant advantage for cementing operations.<br />
