Baker Hughes Introduces Long-Life PDC Bit to Reduce Trips in High Horsepower Drilling Operations

Share:





Baker Hughes Incorporated (NYSE:BHI) announced today the commercial
release of its Dynamus™
extended-life polycrystalline diamond compact (PDC) drill bit
which
can significantly reduce drilling costs by eliminating trips to replace
bits or bottomhole assembly (BHA) tools that wear out in high horsepower
drilling operations. The Dynamus
bit
is built on a robust frame that incorporates stabilizing
elements to prevent lateral vibrations as well as proprietary cutters
engineered to minimize wear. Reducing vibrations not only extends bit
life, it also helps extend the life of other BHA tools and deliver
smoother drilling performance for improved borehole quality.

"Our customers are demanding more from their drilling equipment than
ever before. They are drilling through harder formations and interbedded
sections using more horsepower, more torque and higher weight-on-bit,"
said Scott Schmidt, Vice President, Drill Bits at Baker Hughes.
"Unfortunately, this often leads to excessive downhole vibrations,
premature cutter breakdown, damage to the bit body itself or some
combination of the three, and that it turn leads to unplanned trips. In
high-cost applications, or over the course of a drilling campaign, these
trip costs, or even the cost of drilling ahead with a damaged bit or
BHA, can add up to millions of dollars."

The Dynamus
bit
includes StayTrue™ shaped diamond insert elements which
stabilize the bit to reduce lateral vibrations by more than 90
percent—mitigating vibration-induced damage to both the bit and highly
sensitive BHA components containing electronics. The bit's long-life
StayCool™ 2.0 cutters deliver superior performance across a wide-range
of formation types by generating 30 percent less heat than standard PDC
cutters. This reduces wear and premature weakening of the cutters that
is often a result of excessive heat generation.

The Dynamus
bit's
elements and cutters are incorporated into a newly designed
body comprised of an extremely tough matrix material that resists
cracking and is capable of handling extreme operating loads that would
damage conventional PDC bits. A new, holistic Finite Element Analysis
(FEA) protocol was developed and implemented during the design phase to
accurately predict the Dynamus
bit's
reaction to real-world forces. These FEA simulations helped
the design team optimize the bit's blade strength and structure to
minimize risk in the most demanding applications.

In the Delaware Basin, a Dynamus
bit
recently demonstrated its value by increasing a customer's ROP
by 32 percent compared to the average ROP on offset wells drilled
through the same interbedded formations. The customer was able to
complete their section in a single trip, whereas previous wells had
required multiple trips to drill through the same section. When the bit
was analyzed after the job, it had 70 percent less wear damage than the
best offset bit, even though it had drilled further, indicating that the Dynamus
bit
effectively mitigated and withstood the extreme drilling forces
that offset bits weren't able to.

"The Dynamus
bit
is going to deliver significant value for our customers," said
Schmidt. "Now they don't have to rein-in WOB or torque. Instead, they
can harness their full horsepower to drill full sections faster than
ever without worrying about tripping."

This Dynamus
bit
is the first in a new line of long-life bits that Baker Hughes
is developing to help operators address various drilling dysfunctions,
improve performance and reduce costs.

The Dynamus
bit
is the latest example of Baker Hughes' strategy to improve well
efficiency, optimize production and increase ultimate recovery.
