PTech+™ 43 Torque-Turn Test MTS, Waller-Tx, 1-May-2023 Page 1 of 5 Introduction: Torque tests were performed on four PTech+™ 43 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. Bestolife Copper Supreme Special Blend thread compound (1.1 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 32,000 ft-lb (60% of calculated torsional yield, adjusted for 1.1 FF) was used for each torque cycle applied to tool joint Set A and Set B. An aim makeup torque value of 37,300 ft-lb (70% of calculated torsional yield, adjusted for 1.1 FF) was used for each torque cycle applied to tool joint Set C and Set D. Torque-turn data (makeup and breakout) was record 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 each tool joint set. Applied torque and turn data (makeup and breakout) was record for all cycles. The test was performed to validate connection calculated torsional yield, and for comparison to torque-turn testing performed by PTech Drilling Tubulars, LLC. (PTech Drilling Tubulars, LLC test results are contained in Stress Engineering Services, Inc. report Project No 1202628, dated 8-March-2014.) The torque to yield test was the final test performed on each tool joint set. 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 5.250” OD by 3.000” 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.

The unit is a continuous drive (rotation) 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 Bestolife Copper Supreme Special Blend 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. 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 32,000 ft-lb was used for all makeup cycles performed on Tool Joint Sets A and B. An aim makeup torque value of 37,300 ft-lb was used for all makeup cycles performed on Tool Joint Sets C and D. The makeup torque values represent TSC-DP’s recommended makeup torque and maximum makeup torque, respectively. Both makeup torque values include adjustment for 1.1 friction factor thread

PTech+™ 43 Torque-Turn Test MTS, Waller-Tx, 1-May-2023 Page 3 of 5 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. 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: (All Tool Joint Sets) 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 the display clearly 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. 4. Torque-turn data (makeup and breakout) was recorded for each tool joint set.

PTech+™ 43 Torque-Turn Test MTS, Waller-Tx, 1-May-2023 Page 4 of 5 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 0.0095 7 77.6 80.3 79.1 2/32 B 0.0095 8 76.6 80.7 79.1 4/32 C 0.0105 6 77.3 80.5 78.7 2/32 D 0.0085 11 73.6 78.0 76.0 13/64 Internal shoulder gap based on connection lengths prior to start of test (see Appendix C inspection report) Set A and B aim makeup torque = 32,000 ft-lb (60% TY, adjusted for 1.1 FF) Set C and D aim makeup torque = 37,300 ft-lb (70% TY, adjusted for 1.1 FF) Multi-cycle testing performed on Tool Joint Sets A, B and C was successful in reaching the goal of three consecutive makeup cycles with no change in relative position of the shoulders. Three consecutive makeup cycles with no change in position of shoulders was not achieved on Tool Joint Set D. Due to constraints in allotted time at the test facility, Set D multi-cycle testing was suspended prior to achieving the goal. Set D test results were noted as varying from test results obtained on the other tool joint sets. The breakout torque ratio was lower, the cycle count was higher, and the relative movement between shoulders was higher. Cause of deviation in Set D test results was not identified. Visual inspection was performed on each connection after completing the multi-cycle make and break test. No visible damage was observed on the seal shoulder or internal shoulder. Light roughness, burnishing, was observed on thread load flanks of Set A pin, Set A box, Set B box and Set C box. Light burrs were detected on Set D pin, on the thread load flank crest radius located approximately 1.25” from the seal shoulder. A light step was detected on Set D box, located on the thread load flank adjacent to the root radius on the first and second threads adjacent to the Higbee thread start. All damages were considered to be minor and no connection repairs were required prior to performing the torque to yield test. Select features were measure on each connection and documented. 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 Appendix D for inspection report performed after completing the multi-cycle torque test. Refer to Attachment A for photographs of tool joint sets after completing the muti-cycle torque test.

Refer to Appendix D inspection report for connection length data. Calculated torsional yield = 53,290 ft-lb (adjusted for 1.1 FF) The torque to yield curve for the tool joint sets is shown in Appendix F. For comparison purposes the tool joint sets are plotted on one chart. The flat horizontal portion of the curve indicates yielding of the connection. For all tool joint sets, the torque to yield curve indicates the connection torsional yield exceeded the calculated torsional yield value. 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+™ 43 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 74.7%. 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. For reference purposes, PTech+™ 43 testing performed by PTech Drilling Tubulars, LLC (4 tool joint sets, 3 cycles per set) resulted in a breakout torque ratio of 80.4% min single, 84.9% max single, and 82.7% average. It is noted the PTech Drilling Tubulars, LLC test was performed using a different bucking unit (C & H Bucking Services), Jet Lube Kopr-Kote thread compound (1.15 FF), and an obsolete PTech+™ 43 connection design that has a smaller pin nose OD than the current design. For comparison purposes, a TSC-DP customer performed a make and break test on the TSDS42 connection at MTS using the same hydraulic bucking unit and thread compound used for the tests performed in this report. Based on testing of three tool joint sets, one cycle per set, the TSDS42 breakout torque ratio was 78.4%, 79.0% and 79.3%. The same customer testing resulted in a breakout torque ratio of 81.0%, 81.9% and 82.3% for the same TSDS42 tool joint sets using Jet Lube Kopr-Kote thread compound. 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 all tool joint sets as evident by a tight grouping of the torque-turn curves from 0 to 50,000 ft-lb applied torque. While the precise yield point cannot be identified on the torque-turn curve, the flat section of the curve for all tool joint sets exceeded the calculate torsional yield value for the connection. The average peak torque applied to the four tool joint sets was 59,270 ft-lb versus the connection calculated torsional yield of 53,290 ft-lb (adjust for 1.1 FF). For comparison, the peak applied torque for the Ptech Drilling Tubulars, LLC torque to yield test was 56,095 ft-lb, 56,113 ft-lb and 56,731 ft-lb.
