HOUSTON –Halliburton (NYSE: HAL) announced today that its TDReam tool is one of the winners of OTC’s Spotlight on New Technology awards.
The TDReam tool is an innovation over traditional reamers, which are typically housed above rotary steerable and logging-while-drilling tools in the reaming-while-drilling assembly. A typical reamer creates a long rathole that requires an extra trip to enlarge the hole to total depth. By contrast, the TDReam integrated reamer is positioned between the drill bit and the rotary steerable system to enable rathole length to be reduced to less than 3 ft (1 m) without the extra trip.
The TDReam tool is activated once it reaches total depth to enlarge the rathole left beneath the reamer. This service allows casing and cementing operations to be performed without the need for a dedicated rathole cleanout beforehand. At a spread rate of $900 per minute, the cost of an extra trip could run up to $2 million using a traditional reamer. The TDReam tool saves time and money, and reduces the risks inherent with multiple trips down hole and pipe handling operations at the surface.
Francisco Tarazona, vice president of Halliburton Drill Bits and Services, noted, “The TDReam tool is a unique technology solution for challenges related to rathole length. It eliminates the need for a dedicated rathole drill and cleanout, reduces equivalent circulating density, and lessens the risk of cement contamination.”
