1 Advancing Reservoir Performance Wellbore Cleanup Tools and Displacement Chemicals

2 Wellbore Cleanup Tools and Displacement Chemicals Introduction Since the first oil well was drilled in the late 19th century, there has been an ongoing battle with debris and residue hindering well completions and production. Debris and residue generated from drilling, milling, and perforating can accumulate within the riser, BOPs, casing and liner strings during the completion of a well. This extraneous material not only has the potential to interfere with the installation and performance of the completion and workover systems, but it can also damage the formation. It is critical to remove all debris and residue in the wellbore and displace the drilling fluid to clean completion brine before the well is completed. Baker Hughes provides a comprehensive portfolio of products and services for wellbore cleanup and displacement including reliable and effective wellbore cleanup tools and a full range of displacement fluids. With decades of experience in completions, displacement, and wellbore cleanup, Baker Hughes has the engineering capability to design the right solution for your well. Furthermore, we have the global infrastructure to support your operation, and our experienced field personnel perform each wellbore cleanup and displacement job safely and efficiently to reduce completion risk and maximize production for each and every well Baker Hughes Incorporated.

6 Section 1 Wellbore Cleanup Tools and Displacement Chemicals Casing and Liner Cleaning System Efficiently remove wellbore debris and displace fluid in one trip The Baker Hughes casing and liner cleaning and displacement solution performs multiple casing and liner operations in one trip, saving operating time and cost and eliminating risk associated with additional runs. This optimized system can perform cement drilling, liner top dressing, casing and liner cleaning, polished bore receptacle (PBR) polishing, and fluid displacement operations. We recommend combining our mechanical wellbore cleanup (WBCU) system with Baker Hughes fluids and chemicals to enhance system performance. A typical bottomhole assembly (BHA) for casing and liner cleaning is primarily composed of two subassemblies of tools from the Baker Hughes X-Treme Clean portfolio. Depending on well characteristics, tools can be selected from either the Baker Hughes Extended Performance (EP) or Extreme Performance (XP) platforms. A typical upper assembly includes a wellbore filter, casing brush, downhole magnet, circulation valve, casing scraper, and top dress mill. This upper assembly is used primarily for casing cleaning. The filter validates the cleanliness of the well by filtering any fluid while pulling out of hole. A Baker Hughes downhole magnet removes any ferrous debris from the wellbore and the circulation valve boosts annular flow rates at the liner top. The casing scraper and top dress mill remove tough debris from the casing inside diameter (ID) and dress off the liner top. A typical lower assembly is primarily for liner cleaning and consists of a casing scraper, downhole magnet, casing brush, PBR mill, and a mill or bit. The scraper and brush remove tough debris and thoroughly clean the casing ID. The PBR mill removes any debris from the PBR extension ID, while the bit on bottom cleans or mills over tight spots and restrictions. This mechanical WBCU system can be configured with other downhole assemblies to effectively complete cement drilling operations in one trip. In addition to the mechanical components of the system, Baker Hughes provides world-class displacement chemicals for casing and liner cleaning applications. The MICRO-PRIME system is the premier displacement technology offered in the industry. Composed of PRIME 100 and PRIME 770 additives, the MICRO- PRIME system is a blend of specially selected surfactants that work synergistically to clean and water-wet all downhole surfaces. BAKER CLEAN 5 and BAKER CLEAN 6 systems also work in tandem to provide a clean wellbore and are approved for use in the North Sea. The WELL WASH system of products can be used for oil-based mud (OBM), synthetic oil-based mud (SOBM), and water-based mud (WBM) to effectively clean the wellbore before completion operations. DISPLEX modeling software can be used in planning and troubleshooting displacement operations.

8 Section 1 Wellbore Cleanup Tools and Displacement Chemicals Wellbore Cleanup and Displacement Solution for Shallow Water Optimize completion with high-performance, integrated, one-trip WBCU system A successful wellbore cleanup (WBCU) and fluid displacement is the first step to an optimum completion. Particularly in an offshore well, debris that is not removed from the wellbore, including from areas such as the blowout preventer (BOP) stack and liner top, can cause problems and operational risks during completion. Baker Hughes provides a comprehensive WBCU and displacement solution, including mechanical tools, fluids, and services. The Baker Hughes X-Treme Clean Extended Performance (EP) WBCU and displacement system for shallow water applications cleans risers, BOPs, casing, and liners. It can also perform liner top dressing, cement drilling, liner-top integrity testing, fluid filtration, and fluid displacement. Field-proven for more than a decade, this system can efficiently and reliably accomplish WBCU, displacement, and a variety of jobs in one trip, saving operating time and cost. Several tools compose this downhole assembly. Typically these tools are selected from the X-Treme Clean EP platform of WBCU tools. However, tools can also be selected from the Extreme Performance (XP) platform when more challenging conditions are encountered. The clean bore riser brush cleans the inside diameter (ID) of the riser, and the debris is captured in the integrated boot basket. The BOP jet sub increases the fluid velocity and jets the cavities in the BOP stack. Wellbore fluid is filtered in the multitask wellbore filter, which is also used to verify the cleanliness of the fluid. The stabilized, nonrotating Baker Hughes EP ULTRA-CLEAN casing scraper removes mud, cement sheath, and any additional scale without damaging the casing ID. The EP ULTRA-CLEAN casing brushes are also stabilized and use nonrotating brushes, and they clean the casing ID to remove scale, rust, mud, and cement residue effectively without causing damage. The Baker Hughes EP Grabitz magnet collects ferrous debris from the wellbore. The J-type circulation swivel or full-function valve boosts the annular velocity of the downhole fluid to effectively remove debris from the wellbore. It is typically run above the liner top where there is a change in casing size. The Baker Hughes EP ULTRA-CLEAN casing scraper with integrated dress-off mill is used immediately above the liner top, cleaning the casing ID and dressing the liner top. This operation helps the installation of seal assemblies following the WBCU operation. The wellbore test packer or inflow test packer performs a liner top integrity test during the wellbore cleanup and displacement run. Baker Hughes also provides world-class displacement chemicals to suit every application. The MICRO-PRIME system is the premier displacement technology offered in the industry, and is used to clean and displace water-based mud (WBM), oil-based mud (OBM), and synthetic oil-based mud (SOBM). Composed of PRIME 100 and PRIME 770 additives, the MICRO-PRIME system uses Baker Hughes proprietary Mesophase microemulsion technology with a blend of specially selected surfactants that work synergistically to clean and water-wet all downhole surfaces. The PRIME 770 additive is solvent-free and is formulated to perform in high density brines. The BAKER CLEAN systems BAKER CLEAN 5 and BAKER CLEAN 6 also work in tandem to provide a clean, water-wet wellbore and are approved for use in the North Sea. The WELL WASH system of products can also be used for wellbore cleanup of WBM, OBM, and SOBM in less complex wells before completion operations. DISPLEX modeling software can be used to help plan and troubleshoot displacement operations. Baker Hughes has extensive WBCU and displacement experience globally. Based on your specific well conditions, we design optimum, fit-for-purpose WBCU and displacement programs that deliver flawless performance.

10 Section 1 Wellbore Cleanup Tools and Displacement Chemicals Wellbore Cleanup and Displacement Solution for Deep Water and Ultradeepwater Ensure successful debris removal and displacement operations in extreme conditions A successful wellbore cleanup (WBCU) and fluid displacement is the first step to an optimum completion. Particularly in an offshore well, debris that is not removed from the wellbore, including areas such as the blowout preventer (BOP) stack and liner top, can cause problems and operational risks during completion. In deepwater and ultradeepwater applications, the risks associated with debris within the wellbore have become even more significant due to the immense costs of operating in these environments. Baker Hughes provides a comprehensive WBCU and displacement solution including mechanical tools, fluids, and services. The Baker Hughes award-winning X-Treme Clean Extreme Performance (XP) one-trip WBCU and displacement system is designed for deepwater and ultradeepwater applications. It includes tools for riser and BOP cleaning, casing and liner cleaning, liner-top dressing, cement drilling, liner-top integrity tests, fluid filtration, and fluid displacement. It can perform all of these operations in a single trip, saving operational time and cost and reducing nonproductive time (NPT). The X-Treme Clean XP tools feature higher-than-drill-pipe torque and tensile strength, large flow area, and highest allowable rpm ratings for the most effective WBCU in challenging deepwater environments. The XP riser brush and boot basket clean the riser by brushing the inside diameter (ID) and capturing debris in the integrated boot basket. The BOP jet sub increases fluid velocity and jets the cavities in the BOP stack. Wellbore fluid is filtered and debris is collected in the XP multitask wellbore filter. Additionally, the filter can be used as a key point indicator to verify the cleanliness of the wellbore fluid. The XP casing scraper is nonrotating and is used to remove mud, cement sheath, and any additional scale without damaging the casing ID. The stabilized and nonrotating XP casing brush further cleans the casing ID to remove scale, rust, mud, and cement residue. The XP magnet collects ferrous debris from the wellbore. The circulation valve boosts the annular velocity of the downhole fluid to effectively assist circulation and displacement in the wellbore. A liner top dress mill and polished bore receptacle (PBR) mill can be used to dress off the liner top and clean the PBR in the same trip. If needed, the wellbore test packer or inflow test packer is used to perform a liner-top integrity test during the WBCU and displacement run. The Advantage torque and drag program can be used to simulate the torque and tensile in the bottomhole assembly and drillpipe to ensure a successful operation. Baker Hughes displacement spacer systems are designed to optimize the WBCU process and minimize waste generation when displacing drilling fluids before the completion process. For deepwater applications, Baker Hughes recommends using the MICRO-PRIME or BAKER CLEAN displacement systems for these demanding applications. Our MICRO-PRIME fluid spacer system is advanced detergent technology composed of specially selected surfactant blends designed to maximize the WBCU process. This innovative design uses the Baker Hughes proprietary state-of-the-art Mesophase microemulsion technology to clean and water-wet all oily surfaces, even at high levels of oil- or synthetic-based mud contamination. The MICRO-PRIME system uses a transition weighted spacer designed to efficiently displace water-based mud (WBM), oil-based mud (OBM), or synthetic oil-based mud (SOBM) out of the wellbore while initiating the cleaning process. This is followed by a solids-free, Newtonian brine cleaning spacer to completely remove all oil- and water-wet surfaces. The BAKER CLEAN displacement system also provides superior performance and is yellow-rated for use in the North Sea. The BAKER CLEAN system uses a multifunction viscosified, solids-free brine cleaning spacer to clean, water-wet, and carry out dispersed solids from the wellbore. MICRO-PRIME and BAKER CLEAN spacer technology, along with our proprietary DISPLEX modeling software, allows operators to maximize wellbore cleaning efficiency while reducing risks associated with challenging completion operations Baker Hughes Incorporated.

Wellbore cleanup and displacement can be difficult and complex in an openhole completion. A standard Baker Hughes program typically includes fully displacing the openhole section directly to a viscosified solids-free pill before performing full cleanup and displacement operations within the cased hole. The Baker Hughes fluids program minimizes formation damage, maximizes production, and optimizes the cased hole cleanup process. Baker Hughes provides a wide variety of customized completion fluids and chemicals, as well as advanced cased hole displacement fluids including MICRO-PRIME, BAKER CLEAN 5, BAKER CLEAN 6, and WELL WASH systems. Baker Hughes mechanical tools used in casing cleaning typically include X-Treme Clean riser and blowout preventer cleaning tools, casing and liner cleaning tools, junk recovery tools and circulation tools.

14 Section 1 Wellbore Cleanup Tools and Displacement Chemicals One-trip BOP and Riser Cleanup System Reduce risk by efficiently cleaning the riser and jetting the BOP system The Baker Hughes blowout preventer (BOP) and riser cleanup system performs specific BOP cleaning and debris removal operations that are essential to a clean riser and an efficiently functioning BOP. This operation is necessary because debris lodged in the cavities of the BOP stack can prevent the operator from maintaining well control if a kick is encountered. The dedicated BOP and riser cleanup system uses a specific configuration of Baker Hughes X-Treme Clean wellbore cleanup (WBCU) tools. Depending on well characteristics, tools can be selected from either the Extended Performance (EP) or Extreme Performance (XP) platforms. The system is composed of a riser brush and boot basket, BOP jet sub, downhole magnets, wellbore filter, and a mule shoe or bullnose. The riser brush is used to clean the riser inside diameter (ID) and collect debris. When the BOP jet sub is used in the string, the BOP cavities can be cleaned to ensure its functionality. The filter or surface junk catcher is included approximately three joints beneath the BOP jet sub to collect any debris removed from the BOP as well as to filter the wellbore fluid. Baker Hughes downhole magnets remove any ferrous debris from the wellbore. Finally, a mule shoe or bullnose is typically run on the bottom to facilitate the stabbing of the string and tools into the BOP and casing.

16 Section 1 Wellbore Cleanup Tools and Displacement Chemicals One-Trip Wellbore Cleanup and Sandface Completion System for Non-Cemented Liners Reduce NPT and completion costs The Baker Hughes X-Treme Clean wellbore cleanup (WBCU) and sandface completion system for non-cemented liners lets you set the lower completion, perform a liner top integrity test, clean the wellbore, and displace drilling fluid to completion fluid in the wellbore in a single trip. Nonproductive time (NPT) is minimized and the cost of a successful completion is lowered because the system reduces the number of trips to clean and complete a well. Traditionally, two trips are required to clean and complete an openhole non-cemented liner and to perform a sandface completion. In the first trip, the packer setting area is cleaned, the downhole fluid is displaced, and the wellbore fluid is filtered. In the second trip, the sand screen with liner hanger is deployed. In some cases, a trip to perform a liner top integrity test is run after the lower completion is set. This system is composed of two subsystems. Depending on well characteristics, tools can be selected from either the Extended Performance (EP) or Extreme Performance (XP) platforms. The WBCU subsystem consists of a downhole magnet, casing scraper, casing brush (optional), wellbore filter, circulation valve, and a wellbore test packer. The lower completion subsystem run with the WBCU subsystem consists of a Baker Hughes liner hanger, liner hanger setting tool, fluid loss control valve, and standalone screen or slotted pipe. While running in hole, the WBCU tools act purely as a conduit for deploying the lower completion. At the required depth, the liner hanger is set and the setting tool is released from the liner hanger. Integrity tests are performed. The packer setting area is then cleaned by the nonrotating scraper, minimizing any damage to the casing inner diameter (ID). Fluids can then be circulated and displaced with Baker Hughes completions fluids. The circulation valve is activated to boost the annular velocity and facilitate circulation above the liner top. When pulling out of hole, the downhole magnets collect metal debris and the wellbore filter removes any solids from the downhole fluid, bringing them to surface. Contact your Baker Hughes representative or visit to find out how our one-trip WBCU and sand screen completion system for non-cemented liners can help you reduce NPT and completion costs.

18 Section 1 Wellbore Cleanup Tools and Displacement Chemicals Drill pipe Full-function valve VACS Technology for Post-Perforation and Sump Packer Cleaning Remove burrs, clean the sump packer, and verify cleanliness in one trip Combining Baker Hughes field-proven vectored annular cleaning system (VACS ) technology and other wellbore cleanup and fishing tools, this system effectively removes perforation burrs, cleans the sump packer, and verifies the cleanliness of the sump packer in one trip. VACS technology has been ensuring successful cleanup operations and reducing nonproductive time (NPT) since Magnets VACS engine Washpipe Diverter tubes Drill pipe String mill Baker Hughes VACS technology is a highly effective tool used to recover objects and debris such as bit cones, bearings, sand, and metal shavings from the wellbore and carry them to the surface. It creates suction force at the tool base when fluid flows through the jet nozzles, pulling in loose debris or junk from the well into the tool basket. A typical bottomhole assembly (BHA) in a post-perforation sump packer cleaning operation is shown on the left. The BHA may include either the standard VACS debris basket or modular VACS G2 system. In a typical operation, the BHA is run into the hole at a controlled speed, breaking circulation regularly to prevent premature plugging of the tool. When the bottom of the BHA is above the top of the viscous pill or perforation, circulation is broken and working parameters are recorded, including pump pressure, pick-up and slack-off weight, and torque. Pumping begins, slowly washing down and rotating when needed. The assembly is circulated to ensure sufficient hole cleaning and pulled out of the hole, and the magnets and VACS or VACS G2 tool are inspected for debris. The one-trip deburring, cleaning, and sump packer cleanliness verification capability offers significant savings in time and cost. The VACS wellbore cleanup system is designed to operate and perform with other Baker Hughes wellbore cleanup and fishing tools, offering even more flexibility. And the time involved removing perforation burrs, cleaning sump packers, and verifying the cleanliness of the sump packer is considerably shortened. Using Baker Hughes VACS technology over other cleanup methods ensures that you receive the most reliable and cost-efficient solution for your well.

20 Section 1 Wellbore Cleanup Tools and Displacement Chemicals Drill pipe Full-function valve VACS Technology for Packer Plug or Bridge Plug Retrieval Retrieve plugs and remove debris from the wellbore in one trip Baker Hughes vectored annular cleaning system (VACS ) technology is a reliable method to retrieve plugs from the wellbore in the most cost-effective way. It cleans and collects debris on top of the plug and retrieves the plug with the retrieval tool in one trip. The improved flow path through the use of a triple-connection bushing/ported sub/skirt makes this possible. Magnets VACS engine Washpipe Diverter tubes String mill Triple connection bushing/ported sub/skirt VACS technology is commonly used to recover objects and debris such as bit cones, slips, hand tools, bearing, sand, and metal shavings from the wellbore and carry them to the surface. It creates suction force at the base of the tool when fluid flows through the jet nozzles, pulling in any loose debris or junk from the well into the tool basket. A typical bottomhole assembly (BHA) in a packer plug and bridge plug retrieval application is shown on the left. The BHA may include either the standard VACS debris basket or modular VACS G2 system. In a typical operation, the BHA is run into the hole at a controlled speed, breaking circulation regularly to prevent premature plugging of the tool. When the bottom of the BHA is above the top of the viscous pill or perforation, circulation is broken and working parameters are recorded, including pump pressure, pick-up and slack-off weight, and torque. Pumping begins, slowly washing down and rotating when needed. When the retrieval tool is just above the packer plug, circulation ensures hole cleaning while shakers and filtration units are monitored. The plug is released, and the packer plug is pulled out of the hole. The magnets and VACS or VACS G2 tool are inspected for debris. The one-trip cleaning and retrieving capability offers significant savings in time and cost. It is designed to operate and perform with other Baker Hughes wellbore cleanup and fishing tools, offering even more flexibility. And the time involved cleaning and retrieving a packer plug or a bridge plug is considerably shortened.

24 Section 1 Wellbore Cleanup Tools and Displacement Chemicals VACS Technology for Junk Retrieval of Loose Objects in Cased Hole Remove junk and debris quickly and efficiently Drill pipe Baker Hughes vectored annular cleaning system (VACS ) technology effectively recovers small or big junk items such as hand tools or slips from the well bottom using the VACS engine and robust junk basket. VACS technology has ensured successful cleanup operations and reducing nonproductive time (NPT) since The Baker Hughes VACS engine creates suction force at the base of the tool when fluid flows through the jet nozzles, pulling in any loose debris or junk from the well into the tool basket. Full-function valve Magnets A typical bottomhole assembly (BHA) in a cased-hole junk retrieval operation is shown on the left. In a typical operation, the BHA is run into the hole at a controlled speed, breaking circulation regularly to prevent premature plugging of the tool. When the bottom of the BHA is above the top of the fish, circulation is broken and working parameters are recorded, including pump pressure, pick-up and slack-off weight, and torque. Pumping begins, slowly washing down and rotating when needed. When the bottom of the BHA approaches the top of the fish, pumping continues at recommended flow rate to collect loose objects. The assembly is then pulled out of the hole. The magnets and VACS tool are inspected for debris. VACS technology is capable of one-trip cleaning and junk retrieval in different well conditions, offering significant savings in time and cost.

The VACS engine with ball drop allows positive circulation to wash away any fine debris before retrieving the loose objects. Full-function valve Magnets The VACS engine creates suction force at the base of the tool when fluid flows through the jet nozzles, pulling in any loose debris or junk from the well into the tool basket. A typical bottomhole assembly (BHA) in an openhole junk retrieval operation is shown on the left. In a typical operation, the BHA is run into the hole at a controlled speed, breaking circulation regularly to prevent premature plugging of the tool. When the bottom of the BHA is above the top of the fish, circulation is broken and working parameters are recorded, including pump pressure, pick-up and slack-off weight, and torque. Pumping begins, slowly washing down and rotating when needed. When the bottom of the BHA approaches the top of the fish, circulation removes any debris on top of the fish. A dropped ball is landed on the VACS engine ball seat and the pump continues pumping to collect loose objects. A second dropped ball activates the full-function valve, allowing circulation through the mid string, and the assembly is pulled out of the hole. The magnets and VACS tool are inspected for debris.
