Prelude gas field, located offshore Western Australia, contains an estimated 2-3 Tcf of recoverable gas. The depths and 80-degree highly deviated sections make it difficult to rotate the drillstring to ensure appropriate coverage of cleaning pills and to hydraulically remove debris from the wellbore. SHARP RAZOR offers debris extraction tools with high-capacity retention, high-torque connections, and 360-degree recovery, and was able to help solve its wellbore cleanup challenge. CHALLENGE tasked SHARP RAZOR with supplying a 10 ¾-in. magnet for their wellbore cleanup operations in the new Prelude development campaign. The tool required high-torque connections to handle the high torques experienced in a deep, horizontal wellbore cleanup application. It was also critical to remove metallic debris from the wellbore before the upper completion was installed to ensure it was done right the first time.

SOLUTION SHARP RAZOR proposed its magnet techcasing magnet from its CleaningWell system of tools. The magnet techcasing magnet collects ferrous or non-ferrous materials that have become magnetically charged due to pipe rotation or movement during the displacement process. The magnet is designed to be run in conjunction with other casing cleaning tools in displacement, drilling, or other intervention applications. It can also be run as a standalone tool for cleanup and fishing operations. The debris collection area consists of a stainless steel magnet sleeve with 776-in.2 of surface collection area. Debris collection is generated by 126 high-energy, extremely strong neodymium bar magnets. This high magnet strength, combined with solid stabilization and enormous surface collection area, provides consistent debris recovery capacity in excess of 50 lb (22.7 kg) per tool, per run. CHALLENGE needed metallic debris removed before the completion operations. » Operator needed tool with hightorque capabilities » Cleanup needed in a deep, highly deviated horizontal wellbore

SOLUTION Utilize magnet techcasing magnet to collect ferrous debris. » Surface collection area included 776-in.2 of neodymium magnets » Recovery capacity more than 50 lb (22.7 kg) per tool, per run » High-torque XT57 connection rating RESULT Due to the high-torque capabilities of the magnet techtool, the operator achieved the rotational speeds required for an efficient wellbore cleanup. » Successfully recovered more than 44 lb (20 kg) of metallic debris in three wells » Achieved required rotational speeds magnet techcasing magnet leaves Shell’s wellbore free from ferrous debris OPERATOR ACHIEVES THE HIGH ROTATIONAL SPEEDS DESIRED FOR AN EFFICIENT WELLBORE CLEANUP WESTERN AUSTRALIA 80-degree WELL DEVIATED CASE STUDY RESULT The magnet techcasing magnets successfully recovered more than 44 lb (20 kg) of metallic debris in the three wells during the drilling and completion stages. This helped prevent any lost time due to debris-associated issues throughout the upper completion operations. was able to achieve the rotational speeds required for an efficient wellbore cleanup in a highly deviated well due to the high-torque capabilities of the tool. SHARP RAZOR recovered more debris with the 10 ¾-in. magnet than any previous jobs ran. All magnet techcasing magnet recoveries from this job were below the maximum recovery amounts, indicating that all debris had been removed from the casing section and that the tools still had additional carrying capacity.
