PTech+™ 52 Torque-Turn Test MTS, Waller-Tx, 27-April-2023 Page 1 of 5 Introduction: Torque tests were performed on four PTech+™ 52 tool joint sets. For reporting purposes, the tool joint sets were labeled Set A, B, C and D. All tests were performed at Mechanical Testing Services (MTS), located at 20530 Stokes Road in Waller, Texas. Applied torque and turn data was recorded for all makeup and breakout cycles using the facility’s McCoy RP7022 hydraulic bucking unit. Jet-Lube KOPR EXT FF 1.0 thread compound (1.0 friction factor) was used for all torque cycles performed on all tool joint sets. Test Overview and Objectives: Two types of torque tests were performed on each tool joint set; multi-cycle makeup and breakout test and torque to yield test. 1. Multi-Cycle Make and Break Test: (Makeup Torque = 60% and 70% of Calculated Torsional Yield) Multiple makeup and breakout cycles were performed on each tool joint set. An aim makeup torque value of 54,800 ft-lb (60% of calculated torsional yield) was used for the first three torque cycles applied to tool joint Set A. An aim makeup torque value of 63,980 ft-lb (70% of calculated torsional yield) was used for all subsequent torque cycles applied to tool joint Set A. An aim makeup torque value of 54,800 ft-lb (60% of calculated torsional yield) was used for all torque cycles applied to tool joint Set B, Set C and Set D. Torque-turn data (makeup and breakout) was recorded for all cycles. Due to field reported instances of connection loosening while oscillating/rocking the drill string during slide drilling mode, this test was performed to document the connection breakout to makeup torque ratio. After the initial makeup cycle, a punch mark was applied on the box and pin tool joint OD. The punch marks were used to document relative position of the box and pin shoulders at the end of each subsequent makeup cycle. The goal was to perform multiple make and break cycles until 3 consecutive cycles were achieved with no relative change in position of the mating shoulders at makeup. The data would be used to determine: - Does relative position of shoulders stabilized after a given number of make and break cycles - Is relative shoulder position related to the connection breakout to makeup torque ratio - Does relative position of shoulders stabilize at less make and break cycles using a makeup torque value equal to 70% of connection torsional yield versus 60% of connection torsional yield. 2. Torque to Yield Test: A torque to yield test was performed on tool joint Set B, C and D. Applied torque and turn data (makeup and breakout) was recorded during the test. The test was performed to validate connection calculated torsional yield. A torque to yield test was not performed on tool joint Set A due to pin connection thread damage (galled flanks) sustained during the multi-cycle make and break test. It was decided the thread damage would affect the torque to yield test and produce misleading (inaccurate) results. The torque to yield test was the final test performed on the tool joint sets.

PTech+™ 52 Torque-Turn Test MTS, Waller-Tx, 27-April-2023 Page 2 of 5 Tool Joint Samples: All tool joints were randomly selected from TSC-DP inventory. The tool joints were new, manufactured by JST, and had received a 3-cycle connection break-in by JST at time of manufacture. The tool joints were 6.625” OD by 3.750” ID, manganese phosphate coated, and manufactured to specification TSC-0004 Rev 2, with 135 ksi specified minimum yield strength. Tool joint mechanical properties and chemistry reported in the JST quality documentation package are shown in Appendix A. JST traceability markings stamped on the tool joint OD were recorded and are shown in the below table.

The unit is a continuous drive (rotational) system with a maximum applied torque capacity of 105,000 ft-lb. Work pieces are positioned horizontally in the unit. The driving chuck is located in the unit’s head stock and the static chuck (back-up tong) is located in the unit’s tail stock. The drive chuck and static chuck each have six hydraulic ram cylinders that grip the work pieces. The unit is equipped with a data acquisition system that monitors applied torque and turns. The unit has a display screen that plots a torque-turn graph during progression of the makeup and breakout cycle. Refer to Appendix B for hydraulic bucking unit certificate of torque calibration provided by MTS. Test Procedure, Multi-Cycle Make and Break Test: (Makeup Torque = 60% and 70% of Torsional Yield) 1. Prior to start of test, a dimensional and visual inspection was performed on each connection and the data recorded. All connections met new product dimensional requirements. Refer to Appendix C for inspection report. Tool joints were paired in sets and labeled A, B, C and D. Set pairing was maintain during all torque cycles. 2. Test Sequence: 2.1. Box and pin connections were thoroughly cleaned and Jet-Lube KOPR EXT FF 1.0 thread compound applied to each connection. 2.2. Connections were mated together by hand at a work station and manually tightened using a strap tong. 2.3. The tool joint set was loaded in the hydraulic bucking unit with the pin tool joint positioned in the head stock (drive chuck) and the box tool joint positioned in the tail stock (static chuck). The tool joints were positioned such that the hydraulic bucking unit ram cylinders gripped over the tool joint body, away from the connection.

PTech+™ 52 Torque-Turn Test MTS, Waller-Tx, 27-April-2023 Page 3 of 5 2.4. The hydraulic bucking unit was preset to apply a peak makeup torque value established by TSC-DP. An aim makeup torque value of 54,800 ft-lb (60% of TY)was used for all makeup cycles performed on tool joint Sets B, C and D. An aim makeup torque value of 54,800 ft-lb (60% of TY) was used for the first three makeup cycles performed on tool joint Sets A. An aim makeup torque value of 63,980 ft-lb (70% of TY) was used for all subsequent cycles applied to tool joint Set A. The 60% TY makeup torque value represents TSC-DP’s recommended makeup torque and the 70% TY value represents TSC-DP’s maximum makeup torque (both values based on using a 1.0 friction factor thread compound). All applied torque cycles were performed using a speed of approximately 1.5 RPM. 2.5. After application of the initial makeup torque cycle, the tail stock chuck was released and positioned away from the box tool joint. TSC-DP applied a punch mark on the pin and box tool joint OD adjacent to the RSC bevel runout. The punch marks were positioned in axial alignment and used to document relative position of the connection shoulders at the end of each subsequent makeup torque cycle. (Note, tool joint Set C punch marks were applied after the third makeup cycle.) 2.6. The hydraulic bucking unit tail stock was repositioned over the box tool joint and the connection set broken apart. 2.7. The tool joint set was separated and each connection visually inspected for damage that might interfere with subsequent torque cycles. The examination included inspection of threads using a brass pick tool. After visual inspection, fresh thread compound was applied to the connections, and the tool joint set mated by hand and tightened using a strap tong. 2.8. The hydraulic bucking unit was used to reapply the same makeup torque value applied in Step 2.4. Step 2.3 and 2.4 procedures were repeated during reapplication of makeup torque. After each application of makeup torque, the hydraulic bucking unit tail stock was released and positioned away from the box tool joint. A metal Pi taper was used to measure the radial distance between the two punch marks and the data recorded. 2.9. Steps 2.6 through 2.8 were repeated for subsequent make and break cycles until three consecutive cycles were achieved with no change in relative position of the punch marks. 2.10. After achieving three consecutive cycles with no change in relative position of the punch marks, the tool joint set was separated, thoroughly cleaned, and visually inspected for damage. A dimensional inspection of select connection features was performed to ensure the connections were in good condition and suitable for performing a torque to yield test. Refer to Appendix D for inspection report performed at the conclusion of the multi-cycle torque test. Test Procedure, Torque to Yield: (Tool Joint Set B, C and D) 1. Fresh thread compound was applied to each connection and the tool joint set manually tightened using a strap tong. Tool joint set paring from the multi-cycle torque test was maintained for the torque to yield test. 2. The tool joint set was loaded in the hydraulic bucking unit with the pin tool joint positioned in the head stock (drive chuck) and the box tool joint positioned in the tail stock (static chuck). The tool joints were positioned such that the hydraulic tong unit rams gripped over the tool joint body, away from the connection. 3. Makeup torque was applied at a rate of approximately 1.0 RPM. The hydraulic bucking unit display (torque versus turn graph) was monitored during the makeup cycle. The test was concluded once

Page 6

PTech+™ 52 Torque-Turn Test MTS, Waller-Tx, 27-April-2023 Page 4 of 5 the display indicated the connection had yielded, as evident by a change in the slope of the torque-turn curve and when the applied makeup torque exceeded the calculated torsional yield of the connection. Torque-turn data (makeup and breakout) was recorded for each tool joint set. Test Results, Multi-Cycle Make and Break Test: (Makeup Torque = 60% and 70% of Torsional Yield) No test abnormalities occurred during any make and break cycles. A summary of breakout to makeup torque ratio and change in relative position of connection shoulders is shown in the below table. Data for each individual make and break cycle is shown in Appendix E. Refer to Attachment B for MTS torque-turn curves for individual makeup and breakout cycles. Internal Ratio Relative Position Tool Shoulder Breakout to Makeup Torque of Shoulders at Joint Gap Total (%) Last Makeup Cycle Set (in) Cycles Min Max Avg (in) A 0.0103 12 76.8 81.2 79.5 20/32 B 0.0089 3 80.9 81.9 81.4 2/32 C 0.0095 15 75.9 82.0 78.5 5/32 D 0.0086 13 73.9 80.4 75.8 12/32 Internal shoulder gap based on connection lengths prior to start of test (see Appendix C inspection report) Set B, C and D aim makeup torque, all cycles = 54,800 ft-lb (60% of TY and 1.0 FF) Set A aim makeup torque, cycle 1 thru 3 = 54,800 ft-lb (60% of TY and 1.0 FF) Set A aim makeup torque, cycle 4 thru 12 = 63,980 ft-lb (70% of TY and 1.0 FF) The multi-cycle test performed on tool joint Sets A, C and D was successful in reaching the goal of three consecutive makeup cycles with no change in relative position of the shoulders. Due to constraint in allotted time at the test facility, tool joint Set C multi-cycle testing was limited to 3 make and break cycles. Visual and dimensional inspection was performed on each connection after completing the multi-cycle make and break test, refer to Appendix D for inspection report. The purpose of the inspection was to document dimensions on select features susceptible to change (deformation) due to application of makeup torque and to ensure the connections were in acceptable condition for the torque to yield test. Minor dimensional changes had occurred to some features; however, all features were within new product specified dimensional requirements. Refer to Attachment A for photographs of the tool joints after completing the muti-cycle torque test. Light galls were detected on the thread load flank of Set A pin after six cycles at 63,980 ft-lb aim makeup torque. An attempt was made to repair the damage with a nonmetallic buffing wheel. (It is noted the equipment available to use for repair was not ideally suited for dressing threads, and no anti-gall solution was available to treat the repaired areas.) After repair, three additional make and break cycles were performed on tool joint Set A using 63,980 ft-lb aim makeup torque. The tool joint set was reinspected after the third make and break cycle and the light thread gall damage had redeveloped on the pin connection. Due to the damage, it was decided not to use tool joint Set A for a torque to yield test because the damage might produce misleading test results. No visible damage was observed on the secondary shoulder of any connections. A very light gall, roughness, was detected in an isolated area at the extreme outside edge of the seal shoulder on Box D.

Page 7

PTech+™ 52 Torque-Turn Test MTS, Waller-Tx, 27-April-2023 Page 5 of 5 The roughness was considered acceptable and no repair was necessary. No visible damage was detected on the seal shoulder of any other connection. Light burnishing, roughness, was detected on some thread flanks. The condition was considered to be normal wear from repeated make and break cycles. Test Results, Torque to Yield: During tool joint Set B torque to yield test, the maximum applied torque was inadvertently stopped at approximately 86,671 ft-lb. After consulting with MTS management, approval was granted to set the hydraulic bucking unit at its peak rated torque output of 105,000 ft-lb. The peaking torque setting was used for the torque to yield test performed on tool joint Set C and D. A summary of the torque to yield test data is shown in the below table. Peak Ratio Internal Applied Peak Breakout Tool Shoulder Makeup Breakout to Joint Gap Torque Torque Makeup Set (in) (ft-lb) (ft-lb) (%) A 0.0074 - - - B 0.0094 89,671 71,424 79.7 C 0.0086 104,185 80,308 77.1 D 0.0080 105,321 79,782 75.8 Set A torque to yield test not performed due to pin thread damage that occurred during the multi-cycle make and break test. Internal shoulder gap based on connection shoulder to shoulder length prior to start of torque to yield test, refer to Appendix D inspection report for connection length data. Connection calculated torsional yield = 91,400 ft-lb (1.0 FF). The torque to yield curve for each tool joint set is shown in Appendix F. For comparison purposes the tool joint sets are plotted on one chart. Refer to Attachment B for MTS torque-turn to yield curves for individual makeup and breakout cycles. Summary and Comments: The multi-cycle torque test shows the PTech+™ 52 connection breakout torque is consistently in the range of 75% to 80% of the applied makeup torque. The predicted breakout torque ratio for the connection is 79%. The predicted breakout torque ratio is a reference value calculated using the API torque formula modified with a negative value assigned to the useful work component. No significant change in the breakout torque ratio was observed during the multi-cycle make and break test. The results suggest the industry standard 3-cycle break in operation using the recommended makeup torque value is suitable for new drill pipe connections. No correlation was observed between the breakout torque ratio and change in shoulder position. The torque to yield test indicated consistent torque-turn performance for the tool joint sets. While the precise yield point cannot be identified on the torque-turn curve, the test does indicate the torsional capacity of the connection exceeds the calculated torsional yield.
