GaugePro EchoControl and confirm reamer operations in real time, eliminate dedicated rathole trips, and improve operational efficiency.
Eliminate the unknown with the GaugePro? Echo on-command reamer, the first digital reaming tool in the market to provide real-time operational assurance in high cost-per-foot drilling applications.
The wired, modular GaugePro Echo reamer can be placed anywhere in the Baker Hughes bottomhole assembly (BHA), an especially effective feature for rathole reaming. When placed near the bit, the traditional second rathole reaming run is eliminated, wellbore conditions are improved, and casing can be run that much faster.
The GaugePro Echo digital reamer also adds assurance by powering through as many activation cycles as needed along with the long sought-after real-time confirmation of blade status and position. It will also send back information on oil pressure, oil temperature, and tool vibration in real time.
Baker Hughes GaugePro Echo on-command digital reamers advance reaming capability for better economics by putting real-time downhole tool control in the hands of the operator. Through proprietary technology, unknowns are known, limitations are removed, and nonproductive time (NPT) is reduced as flexibility, controlled operation, hole enlargement, and rathole drilling work together.
Gain control and confidence with real-time communication.
The wired capabilities of the GaugePro Echo reamer enables operators to use real-time commands to deliver unlimited blade activation and deactivation, and receive information on blade status and position, oil pressure, oil temperature, and vibration. This rapid response saves a trip by confirming tool functionality, provides operational insights into downhole conditions, and allows for fast adjustment of drilling parameters so that runs can be extended even farther.
Work smarter, not harder.
The GaugePro Echo digital reamer aids intelligence to eliminate the extra steps and constraints typical of other reamers. It operates independently of drilling parameters and pump flow rates, can be placed multiple times anywhere within the bottomhole assembly (BHA), and drills and reams in one run—all the way to the last 15 feet (4.6 meters) of the rathole.
Mitigate NPT and risks.
In high cost-per-foot applications, every minute saved impacts the bottom line. The GaugePro Echo digital reamer dramatically reduces expensive NPT incurred with other mechanical and hybrid digital reamers that limit drilling parameters, stop operations, force drillers to pull out of hole prematurely, and require a second rathole trip.
Drilling and reaming the rathole in one run reduces pipe handling and rig floor time, along with associated health, safety, and environmental (HSE) risks. Additionally, triple-redundancy failsafe measures ensure that the reamer always trips out of hole, so that operators can stay on schedule.
When run with Baker Hughes drill bits, the GaugePro Echo reamer makes for even smoother, energy-focused reaming that creates less vibration, protects tools, and drills faster. The premium cutters used on the GaugePro Echo reamer increase ROP and provide durability to smooth out longer runs, and up-drill cutters eliminate swelling sections when tripping out of hole. And with an integral stabilizer, steerability is improved when used with rotary steerable systems.

Location: Brage Field, North Sea
During a recent run in the Brage field, an operator faced issues with wellbore stability and equivalent circulating density (ECD) while drilling a 12?-in. section in the Draupne formation. The formation is known to be unstable and can cause tight spots that pose risks for pulling the bottomhole assembly (BHA) out of hole or running casing down to desired depths. The planned total depth (TD) for the section was below the Draupne shale, where calcite stringers were present. This meant the length of the rathole had to be reduced to a minimum in order to successfully install the 10?-in. casing. Exposure of the formation in the opened hole also had to be minimized to reduce the possibility of hole collapse.
Unfortunately, the placement of the underreamer above the measurement-while-drilling or logging-while-drilling tools would leave a 154-ft (50-m) long rathole and increase the risk of a poor casing cement job and hole stability problems in the section. Baker Hughes recommended the use of the GaugePro? Echo on-command digital reamer, placed close to the bit, to eliminate the need for an additional rathole elimination run, removing the risks associated with it and saving rig time.
Baker Hughes built a BHA that included a secondary near-bit GaugePro Echo reamer directly behind the steering unit, with its cutter blades placed 33 ft (10 m) behind the bit, and the main GaugePro Echo reamer placed 105 ft (32 m) behind the bit.
In one run, the entire section was simultaneously drilled and underreamed to TD. The first 3,491 ft (1064 m) were drilled while simultaneously opening the hole to 13?-in. with the main underreamer. The remaining 233 ft (71 m) were drilled and reamed with both the main and the near-bit reamers activated. The rathole length was reduced to 33 ft (10 m) in the same drilling run, saving 3 days of rig time. The 10?-in. liner was then run to the desired depth. Minimal vibrations were recorded in the interval where both reamers were activated and stick/slip was nominal. After the run, an inspection of the reamer blades showed good performance and little wear.
As a normal practice, operators using a near-bit reamer typically drill to TD with the main reamer activated, and then pull back to ream the rathole with the near-bit reamer. For the first time, the GaugePro Echo main and near-bit reamers were simultaneously activated while drilling and run in tandem to TD. This removed the need to pull back to open the rathole with the near-bit reamer after reaching TD. The main reamer stabilized the BHA while the near-bit reamer eliminated rathole and reduced downhole vibration. Simplification of the drilling and reaming operational workflow resulted in rig-time savings and superior drilling performance.
