FORT WORTH, Texas, March 12, 2012 /CNW/ - For the first time, a single Ulterra bit has drilled the entire intermediate section of the Tattoo field, located in Northwest Canada. An 8.5" (216mm) U513M drilled both the vertical and build sections with the same bottom hole assembly, saving the operator two trips and $72 per-meter versus the best offset and $570,000 when compared to the average of six section offsets in the field.
Ulterra's aggressive directional philosophy and a high ROP design enable the U513M to maintain high instantaneous rates of penetration (ROP) required in the drill-out as well as the ability to aggressively build angle with good tool face control. This single run is especially difficult in areas such as the Tattoo field, where a bit is required to drill through several hard carbonate packages only to kick off and build into formations like the very hard Muskwa, known for abundant pyrite and chert which is normally very damaging to PDC bits.
"Solely focusing on ROP in individual sections for this application in Northwest Canada has cost operators a lot of money. Being able to balance ROP in the vertical section while maintaining directional control and cutter durability not only saved the operator over half a million dollars, it also reduced HSE risk exposure and NPT due to unnecessary trips," said Aron Deen, Product Engineering Manager.
"Ulterra is continuously and actively using lessons learned on this excellent run to benefit other drilling applications around Canada and the rest of the world."
