SBE combines Smith Services leading wellbore enlargement technologies, including Rhino XS Reamer and Reamaster, with Smith Technolo-gies innovative drilling products and software systems such as Quad-D bi-center bits and IDEAS. The combination of the knowledge, experience and worldwide resources of SBE will ensure the delivery of high quality well-bores through comprehensive pre-job analy-sis with unmatched on-site performance and post-job review completing the loop. Smith Borehole Enlargement offers a breadth of tools and engineering know-how that will ensure a superior wellbore in any application.

The SBE group has a dedicated Product En-gineering department to develop the best borehole enlargement tools in the industry. A primary tool now available to aid in design is the Integrated Dynamic Engineering Analysis System (IDEAS). It originated with Smith Bits as a design simulation system to improve the bit design process. IDEAS has now been ex-panded to allow the analysis of the entire drill string and each of its components. Reamers, stabilizers, hole openers, MWD/LWD and oth-er components of the BHA can be modeled to predict its behavior in the drill string. The first application of this technology for SBE is the new Rhino XS cutter blocks. Using the power of the IDEAS software, these cutting structure designs can now be tailored to specific applica-tions. The reamer and bit can be optimized with the rest of the BHA System to minimize damaging vibration and maximize overall per-formance.

SBE also has a regionally based Application Engineering group which has at its disposal resources such as Smith Bits Drilling Records System (DRS), which includes more than 500,000 records from oil, gas and geothermal wells from around the world; the Drill Bit Opti-mization System (DBOS) that helps determine the appropriate combination of cutting struc-ture, gauge protections, hydraulic configura-tion and other optimizing features; Yield Point and HART software for hydraulic optimization and ABHAP for BHA design. Around the world, SBE Applications Engineers have the tools and expertise to help the client get optimum per-formance from their UWD operations.

2Underreaming while drilling improves drilling performance while increasing wellbore qual-ity. Every minute of rig time saved directly benefits the bottom line, so building a quality wellbore while drilling the pilot hole signifi-cantly improves the financial return on drill-ing operations. The benefits of underreaming dont stop with eliminating drilling trips. A smooth, concentric wellbore is faster to case and complete, reducing overall rig time while bringing production online faster.

The Rhino XS Reamer is a hydraulically ex-pandable underreamer designed to enlarge the wellbore in a broad range of drilling op-erations. Rhino XS Reamer enlarges the well-bore while drilling, for improved casing run-ning and uniform cementing clearance.

The Rhino XS Reamer is ideal for use with rotary steerable drilling systems, providing a wellbore quality not achievable with other reaming tools. Superior wellbore quality, coupled with a proven history of performance, makes the Rhino XS Reamer the choice for underreaming operations.

Features and Benefits Balanced mass design to eliminate vibra- tion Large bore to accommodate high volume fluid requirements Optimized fluid distribution between bit and cutter blocks Backreams effectively with strategically placed cutters Single-piece body allows for higher ten- sile and torque load capacity Pressure indication at surface to signal full cutter block deployment Lock-up system to prevent cutter block deployment during shoe track drill out

ApplicationsEnlargement of existing pilot holes in a wide range of formations Simultaneous drilling and hole enlarge- ment in operations where reliability is critical Enlargement operations run with direc- tional drilling assemblies Tight tolerance casing designs

4When well profiles and modern drillstrings both become more complex, reducing drillstring vibration becomes an important factor in building a quality wellbore. Vibration shortens the life of drill bits and reamers and reduces the life of MWD, LWD and rotary steerable systems. In severe cases, drillstring vibration can even lead to the BHA being lost in the hole, requiring significant investments of time and money to remediate.

As the industry leader, Smith Borehole Enlargement has developed the Rhino Stabilization System (RSS) to reduce drillstring vibration in demanding borehole enlargement operations. The RSS utilizes an abrasion-resistant sta-bilizer block, deployed with the proven Z Drive system used on the Rhino XS reamer. When run above the Rhino XS, the Rhino Stabilizer provides concentric, stable points of contact in the enlarged hole section, which improves

drilling efficiency and performance by significantly reduc-ing drillstring vibration.

The Rhino Stabilization System is an integrated configu-ration consisting of the Rhino XS Reamer and the Rhino Stabilizer.

Concentric stabilizer increases lateral support in the enlarged wellbore.The introduction of the stabilizer improves dynamic stability. Stabilizer activation method is double ball drop, the same as the Rhino XS Reamer.Use of diamond enhanced inserts in the stabilizer blocks provides superior wear resistance.Configuration is typically run undergauge and 30 feet above the Rhino XS Reamer.

Concentric Staged Hole Openers (SHO) from Smith have been devel-oped from a tradition of application knowledge and technical excellence gained from the success of QUAD-D reaming products. SHO tools incor-porate precision-engineered cutting structures to ensure fast, smoothly drilled and high quality hole open-ing under a wide range of applica-tion conditions, and SHO tools are run successfully on rotary and rotary steerable assemblies in both straight and deviated holes.

While the overall SHO cutting struc-ture is balanced, it is divided into four sections, each serving a specific pur-pose.

Stage One - Pilot BitUsing either a fixed cutter or roller cone bit, the pilot drills the initial hole diameter. A bull nose can also be used to follow a pre-drilled pilot hole.SHO assemblies can be used with multiple pilot configurations for specific applications.SHO can be placed in either a near-bit position or within the BHA for various drill string con-figurations.

Stage Two - SHO Pilot SectionThe pilot section consists of one or two rows of cutting structure to recondition the pilot hole and remove any swelling clays or moving halites.Gauge pads provide initial sta- bilization as the SHO begins the staged reaming process to reduce stick-slip, whirling or off-center tendencies.

Stage Three - SHO PilotConditioning Section (PCS)

Cutting structure is designed to minimize work rates on each cutter position for maximum du-rability. By stress relieving the formation with this intermediate stage, larger hole drilling can be done at a more aggressive ROP.The third stage re-centralizes the SHO on the given well trajectory in both vertical and directional applications.Gauge pads and gauge trimmers provide the main stabilization for the SHO.Gauge pad lengths in the section may vary depending on whether the application calls for a near bit or drill string placement.

Stage Four - SHO ReamingSection

This cutting structure completes the final hole diameter. With the formation already stress-relieved, the reaming section remains ag-gressive even in more competent formations.Gauge trimmers and spiraled gauge pads ensure good hole quality.Gauge pads in this section are kept short in length for direction-al responsiveness.

9The Reamaster-XTU Underreamer has been designed with two large, robust cut-ter arms which facilitate increased cross-sectional area at the underreamer cutter pockets. This also provides more room for larger sealed bearing and PDC cutters for optimized underreaming performance. Gun-drilled ports through the tool de-liver more fluid, giving the operator greater control over the distribution of fluid across the bit and the underreamer cutters.

The ability to run more drilling weight on the tool and spend more time on bot-tom results in cost-effective underreaming. The ability to ensure an existing pilot hole up to 70 percent makes this product ideal for a range of drilling and remedial operations.

Customized cutting structures are available for a broad range of applications and formation types. Sealed bearing milled tooth and TCI cutters are designed specifi-cally for underreaming operations and are capable of delivering penetration rates and cutting structure life comparable to the drill bit. PDC cutters are also available for long intervals.

Fluid flow has been optimized using gun-drilled ports to deliver more drilling mud to the underreamer cutters and the drill bit. This improves hole cleaning efficiency and accommodates the fluid requirements of other downhole tools.

Features and Benefits Forged cutter arms to withstand high shock and torque loads Sealed bearing cutters to provide longer on-bottom life Positive lock to keep arms in the open position Optimized fluid distribution Strategically placed nozzles Milled tooth, TCI and PDC cutting structures are available for a broad range of applications

QUAD-D (Dual Diameter Drift & Drill) bi-center bits provide hole opening through installed casing or liner sections. This family of aggressive matrix and steel body bits is designed to provide durability, reduce torque response, maintain tangents, and reduce sliding time without compromising efficiency when drilling either float equipment or formation. It features a strong, one-piece construction and a very low overall height that enhances directional capabilities when drill-ing with downhole motors.

Vibration is controlled by force and mass balancing, employment of spiral blades and gauge, asymmetrical blade layout, and use of Lo-Vibe inserts. Because of the resulting bit vibration control, bit rotation is maintained about the true bit axis ensuring accurate finished hole diameter and quality. Hydraulic ports are positioned to provide efficient cuttings removal and cleaning of both the pilot and reaming sections. A unique gauge profile prevents cutters from contacting and damaging the casing and also provides a high degree of stabilization and gauge protection. QUAD-D has achieved success in a broad range of applications.

Features and BenefitsDrill-out capability for eliminating trips Directional responsiveness for precise control of wellbore Diameter control for full gauge wellbore Formation-specific design for optimized drilling efficiency

The versatility of QUAD-D products is best demonstrated by the range of applications that they drill. The GeoReam is well suited to be run directly above the pilot bit for directional applications and it is the recommended alternative to the QUAD-D bit in applications in which a PDC cutting structure is not the best option for the pilot bit. Although compact in length, the stability-enhancing technology used in the GeoReam ensures optimal hole quality while drilling. With longer pilot conditioning sections and drill string connections, QUAD-D Reamers are designed to maximize performance in ro-tary applications. The longer pilot conditioning section acts like a string stabilizer to ensure centralization and stabiliza-tion. This tool is intended to be run with various BHA configurations, including rotary steerable systems.

Features and BenefitsDirectional & BHA flexibility for precise control of wellbore Drill-out capability for eliminating trips Diameter control for full gauge wellbore Formation-specific design for optimized drilling efficiency
