Shock Sub The Shock Sub* impact and vibration reduction sub is a drillstring component that absorbs and dampens the variable-axial dynamic loads produced by the drill bit during “normal” drilling operations. Left unchecked, a roller cone bit produces a pattern of “peaks and valleys” on the bottom of the borehole as it rotates. With each revolution of the bit, the cones will tend to follow this sinusoidal contour producing a cyclical oscillation of the drillstring. The Shock Sub interrupts this harmonic cycle by using a bidirectionalspring action enabling it to automatically adjust to a wide range of values for weight on bit (WOB). As axial loads are produced, energy is absorbed through the use of its Belleville spring assembly while force dampening is accomplished by mechanical friction.

Schlumberger BHA Drilling Tools
Diamond-Enhanced Insert Reamer The diamond-enhanced insert (DEI) reamer delivers effective hole reaming across a broad range of applications. Its advanced integral body design incorporates tough, state-of-the-art synthetic DEIs that shear the hole wall, providing a quality, full-gauge wellbore in soft to medium-hard formations.
Flexible design
Each insert is securely brazed into the tool body, so there are no moving parts to wear or fail. Consequently, the tool is not affected by hot hole conditions. It can be placed at any point in the BHA. The tapered body profile enables reaming both downward and upward.
Improved circulation rates
The dual spiral and tapered design facilitates high circulation rates and the efficient transport of cuttings past the tool. The larger circulation area can be an advantage when annular restriction is a concern.

Neyrfor Traditional Neyrfor Traditional* standard turbodrill’s innovative design incorporates stabilizers and straight- or bent-bearing sections for directional-steerable applications, vertical performance, and rotary drilling. The turbodrill’s design allows the driveshaft to rotate at a higher rpm while remaining dynamically stable, which produces unsurpassed ROP without the negative effects of excess torque.
Power and Bearing Section
The Neyrfor Traditional turbodrill is based on a concentric design with a fluid connect rotor and stator-power drive system. These two components are offered in different configurations to produce a range of power characteristics enabling turbodrills to be designed for specific applications, and an all metallic option is available for HPHT conditions. Extended- and high-flow power sections are available in standard tool sizes and configurations. Additionally, a diamondbearing pack design reduces vibration and noise, which can interfere with downhole measurement tools.
The Neyrfor Traditional turbodrill had set the benchmark for downhole drive system reliability: run times of up to 800 hours have minimized NPT caused by downhole tool failures and problems related to HPHT applications.

Neyrfor Delta Neyrfor Delta* high-performance directional turbodrill is specifically designed to meet demanding directional and precision horizontal drilling applications. This high-performance turbodrill has the shortest bit to bend in its class, which enables shorter radius-curve drilling. This capability decreases the course corrections that are common to horizontal and tangent section drilling while increasing ROP. The Neyrfor Delta turbodrill’s stabilizers enhance weight transfer to the bit enabling the turbodrill to maximize borehole cleaning and minimize wellbore rugosity. Both conditions promote wellbore evaluation, casing running, cementing, and minimize problems associated with drilling ahead. Neyrfor Delta turbodrill BHAs run with a proprietary stabilizer placement and optimization software package, which maximize performance and directional predictability while minimizing NPT caused by downhole tool failures and problems related to HPHT applications. Consistent predictable tool face control and increased dogleg capabilities make the Neyrfor Delta high-performance directional turbodrill ideal for directional applications and sidetracking cement plugs and whipstocks.

Neyrfor LC3 Turbodrill Locking Clutch The Neyrfor LC3* turbodrill locking clutch system was specifically designed for drilling and reaming environments that induce bit sticking. When added to a Neyrfor Traditional* standard turbodrill or Neyrfor Delta* highperformance directional turbodrill configuration, it can help free a stuck bit. The clutch engages when the turbodrill drive shaft stops or the rpm is below that of the rotary string speed. Because the drillstring, turbodrill housing, and output drive shaft are linked together by the locking clutch, operators can apply torque from the top drive or rotary table directly to the bit by engaging the LC3 locking clutch system. Once the bit is freed, the clutch disengages and normal drilling operations can be resumed. Bit type and directional well applications are evaluated on a per-well basis.

And, since the system works without applied torque, the orientation of directional-drilling tools is maintained throughout the jarring operation. The tool also offers the driller an important option: to jar up, or down, with a force ranging from a light blow to an extra-heavy impact.
Accelerator AP tool
The Accelerator AP* impact tool augments the Hydra-Jar AP’s capability by providing additional stretch in the drillstring. In this way, it answers challenges such as hole drag, or if the drillstring is not heavy or long enough. By increasing the velocity of the mass applied to the jar, the Accelerator AP ensures optimum impact force from the Hydra-Jar AP.
Jar-Pact Analysis Program
The Jar-Pact* impact tool BHA placement software analysis program includes proprietary software that enables Schlumberger engineers to model the placement and performance of the AP Impact system. This ensures that the Hydra-Jar AP and Accelerator AP will deliver superior, real-world performance for the customer’s specific application. Using information from the operator’s well plan, including wellbore and BHA parameters, the Jar-Pact analysis program determines the optimum placement for impact tools.

Jar-Pact Program and Data Acquisition Program Jar-Pact Program
The Jar-Pact impact tool BHA placement software allows our engineers to model the placement and performance of the AP Impact system to ensure that the Hydra-Jar AP double-acting hydraulic drilling jar and the Accelerator AP impact tool will deliver superior performance in your specific application.
Optimum placement of jar in the BHA
Using information from the operator’s well plan—including borehole and BHA parameters—the software recommends the optimum placement for the tools. This is a critical requirement in order to avoid locating the tools in or near the drillstring neutral point or transition zones. The Jar-Pact software also ensures that the ratio of the hole size to the size of the tools is within recommended guidelines.
Data Acquisition Program
The Data Acquisition Program ensures that all AP Impact tools are tested to specification before being sent to a wellsite. The system uses two pressure transducers to perform both a push and a pull test for both short and full detent. A laser rangefinder device is used to measure stroke length. The results, which include the test readings, tool serial number, date and time, are entered in a reference database and can be viewed as raw data or in a graphical format.

Hydra-Jar AP The Hydra-Jar AP double-acting hydraulic drilling jar is used to amplify the force applied at surface in order to free stuck drillstem components during drilling or workover operations. The direction of jarring can be both up and down. The jar uses a unique temperature-compensation process to provide consistent impact, blow after blow, and hightemperature seals that make it the best choice for hostile drilling conditions. In most applications the tool should be run in conjunction with the Accelerator AP tool to increase the impact while protecting the drillstring and surface equipment from shock.
Consistent performance controlled by driller
The Hydra-Jar AP tool gives the driller the operational flexibility of controlling the direction (up or down), force, and frequency of impact. The tool is balanced to hydrostatic pressure through ports open to the wellbore, ensuring consistent hitting performance regardless of changes in downhole pressure. It is also temperature-compensated through the use of a unique detent system. This provides more consistent loading and firing of the jar over a broad range of borehole temperatures. These features—combined with careful materials selection and field-proven engineering—deliver a uniquely rugged, reliable downhole impact system.
Suitability for all drilling environments
The Hydra-Jar AP drilling jar performs effectively in every drilling environment—land or offshore, vertical or deviated wells, and ultradeep or ultrahot boreholes. Because the system works without applied torque, directional drilling tools maintain their orientation throughout the jarring operation. The jar may be run in compression or tension, enabling optimized placement in the string.

Accelerator AP
Maximum jarring impact in any hole profile
Used in conjunction with the Hydra-Jar AP double-acting hydraulic drilling jar, the Accelerator AP tool combines the advantage of jarring up, down, or up-and-down with hydraulic fluid for maximum jarring impact. By increasing the velocity of the mass applied to the jar, the Accelerator AP tool ensures optimum impact force from the Hydra-Jar AP tool. When used with the Hydra-Jar AP tool, fluid compression inside the Accelerator AP tool compensates for limited drillpipe stretch in shallow or crooked holes, providing stored energy so that the fish is hit hard regardless of depth. The tool also optimizes jar performance in extended-reach, directional, and horizontal wells, where the stored energy in the drillpipe is lost because of hole drag.

HydraQuaker Re-engineered to deliver 300% more impact force, the HydraQuaker* hydraulic drilling jar’s advanced capability can be traced to the 50 years of experience and impact tool excellence that defined Houston Engineers, developer of the Hydra-Jar AP double-acting hydraulic drilling jar. The new generation HydraQuaker jar’s highly effective detent system ensures more consistent loading and firing of the jar over a wide range of borehole conditions. Designed for cost-effective operation in highvolume environments, the jar is easy to dress, extremely durable, offers dependable hitting performance in any application, and requires little maintenance.
Dependable and adjustable force
repeatedly, ensuring consistent impact to the stuck point regardless of downhole conditions.
Efficient drillstring activation
Once an impact has been delivered, the driller simply raises or lowers the drillstring, and the proprietary metering mechanism resets the HydraQuaker jar to deliver the next impact. There is no need to circulate or cool down, because the jar’s proprietary design enables it to endure high pressures and operating temperatures of up to 300 degF and 450 degF when equipped with its optional hightemperature seals.
Applications ■■
The HydraQuaker jar is capable of higher overpull and impact than conventional impact tools of the same size. Because its impact action does not require buildup torque for firing, its long free stroke maximizes impact, producing consistent and effective jarring force. The HydraQuaker jar’s impact action is fully adjustable downhole: Increasing the upward pull on the drillstring causes the tool to fire up, and slacking off causes the tool to fire down. It can be run in tension or compression, and its large piston area prevents automatic cocking or firing while pumps are operating normally. In addition, the jar’s flex subs provide tool joint flexibility for passing through high dogleg severity intervals.

Borehole Enlargement
Borehole Enlargement Introduction Schlumberger Borehole Enlargement Combines Leading Technologies and Products
Schlumberger combined leading technologies to offer the industry’s best borehole enlargement tools: Rhino XC* on-demand hydraulically actuated reamer, Rhino XS* hydraulically expandable reamer, and Reamaster-XTU* forged cutter arm underreamer, were joined with innovative drilling products and software systems such as, Quad-D* dual-diameter drift drill bits, Quad-D directional drilling products, and IDEAS* integrated drillbit design platform and i-DRILL* engineered drilling system design. IDEAS platform enables analysis of wellbore enlargement components: Bits, reamers, and hole openers can be modeled to predict how they will behave in a drilling application. In the area of wellbore enlargement, IDEAS platform software enables Schlumberger engineers to tailor the Rhino XC reamer’s cutting structure for specific applications. The i-DRILL system accurately simulates the downhole behavior of drill bits, BHA components, and the drillstring and provides operators with a virtual picture that accurately depicts the dynamic downhole drilling environment. This capability enables designers to find optimum solutions for even the most complex drilling problems. Additionally, the simulation and analysis produces balanced drillbit and hole opening cutting structure design information to eliminate excessive vibrations. i-DRILL system design develops more accurate drilling program schedules with reduced risk of unplanned delays—saving the operator time and money.
Rhino XC cutter blocks are designed with the IDEAS platform.
Schlumberger complements this technology with DBOS* drill bit optimization system, which helps determine the appropriate combination of cutting structure, gauge protections, hydraulic configuration, and other optimizing features. Additionally, YieldPoint RT* drilling hydraulics and hole cleaning simulation program, HART* software for hydraulic optimization and i-DRILL for BHA design provide operators around the world with the capability to optimize drilling performance of their underreaming while drilling (UWD) operations. Beyond the latest technologies, Schlumberger can offer key information and management resources: Smith Bits DRS* drilling records system holds more than 3.5 million records from oil, gas, and geothermal wells from around the world. And, Schlumberger has the engineering expertise, experience, and worldwide resources to conduct comprehensive pre-job analysis, unmatched on-site performance, and post-job review. The combination of these technologies and resources form an advanced wellbore enlargement capability—delivering highquality wellbores regardless of the application.

Schlumberger Borehole Enlargement
Rhino XC Reamer Unmatched underreaming performance and actuation control Building on Rhino XS reamer technology, the Rhino XC on-demand hydraulically actuated reamer enables a faster activation sequence than previous generations of hydraulically activated reamers. It efficiently enlarges wellbores for improved casing running, cementing clearance, and equivalent circulating density (ECD) control.
The Rhino XC reamer’s on-demand actuation system provides complete control of reamer cutter block deployment: It uses a flow activation system, which eliminates the need for time-consuming pumpdown device activation that can take up to 30 minutes. This allows the reamer to be placed below ID-restricted BHA components such as MLWD tools. And, with flow actuation control, the Rhino XC reamer provides the fastest cutter block activation and deactivation in the industry.
Reliability with borehole quality
As with all Rhino* integrated borehole enlargement systems, the Rhino XC reamer features the Z-Drive reamer cutter block deployment system to ensure cutter blocks are deployed during activation and retracted when the reamer is deactivated. The Rhino XC reamer is designed for a variety of formations where simultaneous drilling and hole-enlargement reliability are essential. The reamer’s one-piece, balanced design increases torque and loadcarrying capacity while reducing drilling-generated vibrations that produce undergauge and irregular boreholes.
Controls high-fluid volumes for effective cleaning
The Rhino XC reamer’s three nozzles can be changed to ensure optimum borehole cleaning and cuttings evacuation. The tool’s large bore handles high-fluid volumes with optimized distribution between the bit and cutter blocks, as well as the fluid requirements of rotary steerable systems and directional assemblies.
Durability with application flexibility
For extended footage, optional Predator* cutter blocks are available. Equipped with the ONYX* PDC cutters, Predator cutter blocks maximize ROP with cutters that remain sharper longer. ONYX cutters are more thermally stable for greater wear and impact resistance than other PDC cutters. And, single-set placement of each cutter on the cutting profile ensures a more stable and durable cutting structure. The Rhino XC reamer is designed to improve drilling performance over a wide range of applications: from hard and highly abrasive to Rhino XC Specifications Tool Series Overall Body Diameter, in 8000 9250 11625 13000 14250 16000 16000

Reliable hydraulically expandable reamer
The Rhino XS reamer is hydraulically activated and deactivated by pumping fluid through the drillstring and into the tool’s piston bore. A ball-drop activation/deactivation mechanism increases differential pressure when the first ball is dropped by restricting the tool bore, shearing the shear pins and deploying the cutters; pressure indicators at the surface signal full cutter deployment. For applications that require circulation with the cutter blocks in the closed position, an optional double ball drop (DBD) is available. The reamer’s activation/deactivation mechanism prevents fluid flow from deploying cutters during shoe track drilling or whenever circulation is necessary to help avoid stuck BHAs or casing damage.

Predator Cutter Blocks Rhino XC on-demand reamers and Rhino XS reamers can be equipped with Predator cutter blocks, which employ the latest technological advances.
Faster ROP and fewer trips
Predator* cutter blocks use ONYX* PDC cutters, which are more thermally stable, as well as more wear- and impact-resistant than conventional PDC cutters. Extensive testing and analysis is used to optimize every step in the manufacture of these cutters, resulting in improved performance over a wide range of applications, from hard, highly abrasive to interbedded, difficult-to-drill formations. The cutters remain sharp longer, translating into more footage drilled at maximum ROP and substantially reduced drilling costs. Moreover, the single-set cutter placement, which means that each cutter is in a unique location on the cutting profile, results in a more stable and durable reamer cutting structure.
Optimized design
The advanced cutting structure is optimized for maximum ROP with minimum vibration using the industry’s most advanced drillstring dynamics modeling software, IDEAS. This brings application-specific cutting structures to borehole enlargement and avoids damaging vibrational loading of the cutters.
Predator cutter block
The reamer placement and operating parameters are also optimized for performance with the rest of the BHA components. Combining the best cutter with the most dynamically stable design delivers maximum performance in multiple formations, with minimum vibration, a highquality borehole, and maximum ROP.

Rhino Stabilization System As well profiles and the individual components in modern drillstrings become more complex, reducing drillstring vibration becomes an increasingly important factor in building a quality borehole. The Rhino stabilization system is an integrated configuration consisting of the Rhino XS reamer and the Rhino stabilizer, which work in concert to reduce vibration downhole. The Rhino system’s concentric stabilizer increases lateral support in the enlarged wellbore and improves dynamic stability. This impedes vibration that can shorten the service life of downhole tools and surface equipment, slows drilling, results in an irregular borehole and—in severe cases—leads to loss of the entire BHA downhole.
Diamond-enhanced gauge inserts
The Rhino stabilizer is activated by the same ball-drop mechanism as the Rhino XS reamer and is typically run undergauge 30 ft above the reamer. Tungsten carbide and diamond-enhanced inserts in the stabilizer blocks ensure superior wear resistance.

Drilling-Type Underreamer The Drilling-Type Underreamer (DTU) is a tricone underreamer with cutter arms that deploy in response to hydraulic pressure on a pistoncam system. The underreamer runs in conjunction with a drill bit or a bullnose on a bottom-box connection depending on pilot hole condition or project objectives. The tool’s three-arm design can increase the pilot hole diameter up to 75%, depending on tool size. The underreamer’s cutters retract in the absence of hydraulic pressure and the closing force of a piston spring. This enables the tool to be repositioned for selective underreaming or retrieval from the well. The tool allows fluid flow to the bit or bullnose through the bottom connection; flow can be divided depending on the application. Orifice jets can be selected in accordance with existing hydraulics to cool cutters and maintain annular lift of cuttings.
