By application received November 22, 2024, Hilcorp Alaska LLC (Hilcorp), as operator of the Duck Island Unit (DIU) requested authorization for the use of non-custody transfer meters for the measurement of gas consumed to generate electrical power to a third-party data center located on Endicott Satellite Drilling Island. 2. Hilcorp proposes this small-scale pilot project to demonstrate the feasibility of monetizing stranded North Slope natural gas by data centers on the North Slope of Alaska. The pilot project duration will have a limited duration (4 to 5 years). 3. This pilot project involves a non-traditional approach to custody transfer measurement, requiring a waiver of the requirements in 20 AAC 25.228. Pursuant to 20 AAC 25.505, the Alaska Oil and Gas Conservation Commission (AOGCC) may waive a regulation by issuing an order in conformance with 20 AAC 25.540. 4. Pursuant to 20 AAC 25.540, a public hearing was tentatively scheduled for January 16, 2025. On December 5, 2025, the AOGCC published notice of that hearing on the State of Alaska’s Online Public Notice website, on the AOGCC’s website, and electronically transmitted the notice to all persons on the AOGCC’s email distribution list. 5. No comments or requests for a hearing on Hilcorp’s application were received. The scheduled hearing was vacated on January 13, 2025. 6. On January 17, 2025, the Alaska Oil and Gas Conservation Commission (AOGCC) requested additional information from Hilcorp. 7. Additional information was provided by Hilcorp on February 5, 2025, in support of its request for the non-traditional approach to custody transfer measurement of natural gas. 8. Hilcorp’s application and supplemental information, AOGCC records, and publicly available information provide sufficient information upon which to make an informed decision. Other Order 218 March 13, 2025 Page 2 of 4 FINDINGS: 1. Hilcorp is the sole owner and operator of the DIU located offshore North Slope, Alaska. Included within the DIU is the Endicott oil and gas field. 2. Produced fluids from the DIU are processed at the Endicott Main Production Island within the unit. Natural gas is used for fuel gas at Endicott, and Hilcorp reports there is excess power generation capacity available at the Endicott facility. 3. Hilcorp will sell excess power to the third-party data center. 4. Hilcorp proposes to use the existing classical style venturi tube meters (4) associated with power generation turbines to measure the total gas consumed in generating power at Endicott. 5. The volume of gas measured by the venturi meters is included in the monthly gas disposition reporting to the AOGCC. Gas disposition does not require custody transfer measurement quality meters. 6. Hilcorp does not have the ability to segregate gas used to generate power for its Endicott facility from the gas consumed in generating power for the third-party data center. 7. Electrical meters are installed at each Endicott facility power generating turbine and at the third-party data center to measure power consumed. The third-party data center will provide weekly power consumption reports to Hilcorp. 8. Hilcorp proposes the volume of gas consumed to generate power for the data center to be indirectly determined by calculation using the measured total volume of gas consumed at Endicott for power generation and a ratio of the measurements of the electricity consumed by the third-party data center and total electricity produced at Endicott. 9. Hilcorp estimates less than 0.15% of the total gas produced at Endicott will be used by the data center during the pilot project. CONCLUSIONS: 1. Produced gas will be used to generate power for a third-party data center located at the Endicott Satellite Drilling Island. Hilcorp records indicate that data center has already been installed but not connected to the power source. 2. Hilcorp’s pilot project is the first application of its kind under AOGCC jurisdiction. 3. Gas used to generate power for the third-party data center requires measurement with custody transfer quality meters. 4. AOGCC regulation 20 AAC 25.228 incorporates by reference API Manual of Petroleum Measurement Standards (MPMS), as revised dated November 30, 1998. Venturi meters were not recognized for custody transfer measurement until API published MPMS Chapter 14.14, First Edition, March 2023. 5. The venturi tube measurement equipment at Endicott does not meet AOGCC custody transfer measurement requirements nor the provisions of API MPMS 14.14. Other Order 218 March 13, 2025 Page 3 of 4 6. Hilcorp provided historical inspection results for the calibration checks of pressure and temperature transmitters but is unable to produce inspection records for the venturi meters. 7. AOGCC has no experience nor jurisdiction regarding electrical meters. Hilcorp has full access to the data center and is authorized to verify the power consumption reports. 8. The temporary nature of this pilot project, and the small volume of gas involved warrant conditional approval of a waiver to use non-custody transfer meters. 9. Reports of electrical power consumption for Hilcorp’s Endicott operations and the third- party data center fall under AOGCC data retention requirements. NOW THEREFORE IT IS ORDERED: The use of venturi flow meters for determining the custody transfer volume of gas used to generate power for a third-party data center at Endicott Satellite Drilling Island within the DIU is approved, subject to the following conditions: 1. The pilot project as described shall not exceed 5 years from commencement of power sales to the third-party data center. No extensions will be granted unless the measurement system is upgraded to custody transfer standards. 2. The equipment must be as described in the application. Hilcorp must provide information demonstrating conformance and obtain AOGCC approval before changes are made to the equipment or measurement methodology. 3. Hilcorp must: a. Inspect and perform calibration checks of all secondary measurement instruments (static pressure, differential pressure, and temperature) used in gas volume determinations every 3 months. b. Calibrate secondary measurement instruments when repairs or replacement are completed, and within 5 days if a secondary instrument is found out of tolerance during calibration checks. c. Inspect the upstream meter run and venturi tube with a borescope annually. d. Sample and analyze the Endicott facility fuel gas stream annually and confirm the results are used in the gas volume calculations. 4. Hilcorp must notify the AOGCC at least 24 hours in advance for opportunity to witness function checks, calibrations and inspections of the venturi measurement system prior to start/restart of the third-party data center and after repairs and any equipment changes. 5. The following must be available at the time of AOGCC witness: a. Flow parameters used in calculations of the volume of gas consumed by the data center and a log of events that have occurred that impact flow volumes. b. Evidence showing instruments used for calibrations have current certifications traceable to NIST. Other Order 218 March 13, 2025 Page 4 of 4 6. Provide copies of calibration reports within seven days after completing a calibration. The calibration report must include: a. Tolerances for static pressure, differential pressure, and temperature. b. As-found/as-left results for static pressure, differential pressure, and temperature. c. Information about the test equipment used (make, model, serial #, and calibration date). d. An equivalent to a flow computer non-resettable totalizer volume. e. Date the gas composition was last updated in the flow computer, and f. Conditions at the time of calibration (flow rate, static pressure, flowing temperature). 7. Electrical power consumption reports must be available for AOGCC review upon request. DONE at Anchorage, Alaska and dated March 13, 2025. Jessie L. Chmielowski Gregory C. Wilson Commissioner Commissioner RECONSIDERATION AND APPEAL NOTICE As provided in AS 31.05.080(a), within 20 days after written notice of the entry of this order or decision, or such further time as the AOGCC grants for good cause shown, a person affected by it may file with the AOGCC an application for reconsideration of the matter determined by it. If the notice was mailed, then the period of time shall be 23 days. An application for reconsideration must set out the respect in which the order or decision is believed to be erroneous. The AOGCC shall grant or refuse the application for reconsideration in whole or in part within 10 days after it is filed. Failure to act on it within 10-days is a denial of reconsideration.

This pilot project is designed to be a material first step in a broader effort to monetize Alaska’s stranded natural gas resource. The small scale of the pilot and short duration (4-5 years) requires a non-traditional tailored approach to achieve project feasibility. The scope of this pilot project considers the sale of power generated using gas sourced from within the unit. The currently installed gas measurement system has been used in the gas disposition reporting of fuel gas for the turbines to the State. Hilcorp requests approval for using the existing power turbine gas measurement venturi meters, in combination with power measurement for custody transfer of gas to the datacenter for royalty payment purposes. Please find below the response to the AOGCC information request. Text in normal font is the original text from the AOGCC request, Hilcorp responses are shown in italics. AOGCC information request: -Please clarify the expected gas flow rate. Page 1 shows 1.3 MMscf/d; page 2 shows 0 to 2 MMscf/d. Is this per turbine or total per day volume for all turbines. The datacenter is rated for 1.2 MW. The expected datacenter load is estimated 0.9-1.1MW depending on the operating conditions. The typical plant load without datacenter is around 8 MW. At Endicott, Hilcorp assumes a conversion rate of approximately 22.5 MSCF/MWh. This conversion rate will fluctuate with factors such as ambient temperature, wear on turbine, timing of last water wash and machine loading. With the above assumption, this results in a full load fuel gas consumption rate of 0.65 MMSCF/day for the datacenter, and 4.3 MMSCF/day for the plant excluding the datacenter. The datacenter and the plant together require an estimated consumption of around 5 MMSCF/day by the turbines, or about 1.7 MMSCF/day per individual turbine when running on 3 machines. EndicoƩ Fuel Gas to 3rd Party Data Center (Pilot Project),AOGCC Docket OTH-24-028 Page 2 of 5 -Hilcorp indicates that only 3 of 4 turbines are in use. Will that remain a true statement when generating power to the data center? Yes, normally 3 turbines will be sufficient to supply the power to all plant demands, including the data center with adequate spinning reserve. However, if additional activities, for example drilling on highline power, take place, a 4th turbine may be required to support these loads for a limited duration. -No manufacturer data sheet provided for the venturi tubes; please provide The manufacturer data sheet is attached. (Appendix 1&3). -Are there Factory Acceptance Test reports for the venturi tubes (certification) prior to installation in 1985 indicating expected performance and meter accuracy? Records of the factory calibration sheet are shown in appendix 1. -Each venturi tube needs to be identified with a unique meter tag associated with a serial number. o Photos of data plates are not legible The data plates are for the generic measurement system and do not contain the serial numbers for each venturi tube. The individual serial numbers for the venturi tubes are directly on the tubes. The venturi tube serial numbers are: 85-46-0158 through 85-46-0161 (from the original certificate of compliance). APPENDIX 1. -Provide annual inspection reports for venturi tube and quarterly calibration checks for the transmitters (2023 and 2024). Currently the flow meters are not used for gas sales. Therefore, the transmitter calibrations have taken place on an annual basis, and no borescope inspections have been conducted on the venturis. Hilcorp proposes to change this frequency to 1x per year for venturi tube inspection, and 4x per year for pressure and temperature device calibrations once the equipment is being used for datacenter gas volume accounting. The transmitter calibrations have been attached (APPENDIX 2). -The application refers to centralized pressure and temperature transmitter upstream of the venturi meter. Is that 1 pressure and 1 temperature transmitter for all venturi tubes, or one pressure and one temperature transmitter per venturi tube? Pressure and temperature compensation for all four venturi tunes takes place with a shared single pressure and a shared single temperature transmitter. EndicoƩ Fuel Gas to 3rd Party Data Center (Pilot Project),AOGCC Docket OTH-24-028 Page 3 of 5 -Is there a differential pressure device (none referenced in the application)? Each venturi tube uses a model 21151 DP-4-E-22-B5L4 differential pressure device. These instruments were rebranded by Daniels and supplied with the original purchase order. The serial numbers for these transmitters are: 70644, 704642, 704641 and 704643. -How is electrical power measured at Endicott and at Data Center? Meters certified? The power generated by each turbine is measured using Westinghouse Type Mark 1A meters. The serial numbers are: 4501 – Ser. # 5628580 4502 – Ser. # 5628577 4503 – Ser. # 5628578 4504 – Ser. # 5628579 Hilcorp has no records for certification of these meters. While these meters readings are available in the DCS, the DCS read-out goes through a 4-20ma conversion. The Datacenter has a built-in power meter, NOARK, PMA710-3-C 5A AC480V/277V AC/DC85~264V 60Hz The 3rd party will send power consumption reports by email on a weekly basis. Hilcorp has full access to the datacenter and is authorized to verify the power consumption reports with the local indication. Due to security concerns, Hilcorp cannot directly tie-in to the 3rd party power meter at the datacenter. -Appendix 6 (extracted from API MPMS 14.14) appears to apply to a commissioning inspection prior to placing the venturi tubing in service. It is not clear what Hilcorp’s intent is in including this information as the venturi tubes are all installed and have operated. Will this inspection occur for the venturi tube associated with the unused turbine before placed in (or returned to) service? Hilcorp’s intent is to inspect each venturi tube annually using a borescope. You are correct in pointing out that the attached form in Appendix 6 will not be suitable for capturing the borescope inspection findings. Instead of using this form, Hilcorp proposes to simply include the borescope inspection images in the annual inspection report. The inspection data for the tubes is included in Appendix Y. The borescope inspection method and reporting out the images only is also considered best practice for venturi tubes at our Prudhoe Bay facilities. What dictates when turbines swap service (turbine shut down, replaced with turbine previously idle)? Hilcorp endeavors to minimize the number of start-stops on each machine to minimize equipment wear. Turbine swaps generally break down in the planned, unplanned and operational EndicoƩ Fuel Gas to 3rd Party Data Center (Pilot Project), AOGCC Docket OTH-24-028 Page 4 of 5 categories. An unplanned swap will happen when one of the turbines shuts down to protect itself, based on a fault indication. This will trigger a start-up of the stand-by machine and equipment troubleshooting and maintenance on the faulty machine. A planned turbine swap is for equipment maintenance and will typically be planned when a machine reaches a certain run- hour milestone since its last maintenance. The gas generators will typically be inspected and maintained every 50,000 hours, and the power turbine on the SGT-200 units will typically be inspected and maintained every 96,000 hours. Operations will also shut down/start-up the units to balance loads or during facility turnarounds. -Application references ASME MFC-3M for upstream and downstream straight length requirements. We are not familiar with this standard; compare to API. The API 14.14 MPMS does not give a direct requirement for straight lengths in the meter run. Instead, it gives the following guidance: Figure 1. API MPMS 14.14 secƟon 11 - Manual of Petroleum Measurement Standards Chapter 14.14 Venturi Metering of Natural Gas and Other Related Hydrocarbon Fluids - First EdiƟon. March 2023. Helpfully, the manufacturer specification refers to ASME MFC-3M, so both clauses A) and B) from the API MPMS 14.14 are being adhered to. The pipe consists of 2” Schedule XS (ID 1.7”). This corresponds to approximately 21D upstream straight lengths and 24D downstream straight lengths. The requirement with 2 or more 90-degree bends in the same plane is for a minimum of 10.5D upstream and 3D downstream. The requirement with two or more 90-degree bends in different planes is 21D upstream and 3D downstream. The meter run straight lengths comply with ASME MFC-3M (1985) requirements, and with the requirements from API MPMS 14.14 as shown by the stipulations above. -Totalizer Volume – is this available in the DCS? The totalizer volume will not be available in the DCS. The following values will be available in the DCS: Individual fuel gas consumption per turbine Power produced per turbine Total power produced by all turbines online EndicoƩ Fuel Gas to 3rd Party Data Center (Pilot Project),AOGCC Docket OTH-24-028 Page 5 of 5 We request the AOGCC approve the method outline for measuring gas associated with the datacenter power sales at Endicott.

Page 1 shows 1.3 MMscf/d; page 2 shows 0 to 2 MMscf/d. Is this per turbine or total per day volume for all turbines. - Hilcorp indicates that only 3 of 4 turbines are in use. Will that remain a true statement when generating power to the data center? - No manufacturer data sheet provided for the venturi tubes; please provide - Are there Factory Acceptance Test reports for the venturi tubes (certification) prior to installation in 1985 indicating expected performance and meter accuracy? - Each venturi tube needs to be identified with a unique meter tag associated with a serial number. o Photos of data plates are not legible - Provide annual inspection reports for venturi tube and quarterly calibration checks for the transmitters (2023 and 2024). - The application refers to centralized pressure and temperature transmitter upstream of the venturi meter. Is that 1 pressure and 1 temperature transmitter for all venturi tubes, or one pressure and one temperature transmitter per venturi tube? - Is there a differential pressure device (none referenced in the application)? - How is electrical power measured at Endicott and at Data Center? Meters certified? - Appendix 6 (extracted from API MPMS 14.14) appears to apply to a commissioning inspection prior to placing the venturi tubing in service. It is not clear what Hilcorp’s intent is in including this information as the venturi tubes are all installed and have operated. Will this inspection occur for the venturi tube associated with the unused turbine before placed in (or returned to) service? - What dictates when turbines swap service (turbine shut down, replaced with turbine previously idle)? - Application references ASME MFC-3M for upstream and downstream straight length requirements. We are not familiar with this standard; compare to API. - Totalizer Volume – is this available in the DCS? 2 Notice of Public Hearing STATE OF ALASKA ALASKA OIL AND GAS CONSERVATION COMMISSION Re: Docket Number: OTH-24-038 Hilcorp Alaska, LLC (Hilcorp), by letter dated November 22, 2024, filed an application to the Alaska Oil and Gas Conservation Commission (AOGCC) requesting approval of existing non- custody transfer venturi meters within the Duck Island Unit for the measurement of gas consumed in generating power for a third-party data center. AOGCC regulations require hydrocarbon production be measured before severance from the property or unit where produced. Hydrocarbon measurement equipment must be fabricated, installed and maintained in conformance with relevant parts of the API Manual of Petroleum Measurement Standards. While the location of the third-party data center is located within the Duck Island Unit – on Endicott Satellite Drilling Island – AOGCC considers the gas used for powering the third-party data center to be a custody transfer. Hilcorp’s request to use the venturi meters associated with Endicott power generation turbines acknowledges that the meters deviate from the API Manual of Petroleum Measurement Standards. Since this would constitute a waiver of the AOGCC’s regulations at 20 AAC 25.228, scheduling a tentative hearing in accordance with 20 AAC 25.540 is required. This notice does not contain all the information filed by Hilcorp. To obtain more information, contact the AOGCC’s Special Assistant, Samantha Coldiron, at (907) 793-1223 or samantha.coldiron@alaska.gov. A public hearing on the matter has been tentatively scheduled for January 16, 2025, at 10:00 a.m. The hearing, which may be changed to full virtual, if necessary, will be held in the AOGCC hearing room located at 333 West 7th Avenue, Anchorage, AK 99501. The audio call-in information is (907) 202-7104 Conference ID: 518 816 779#. Anyone who wishes to participate remotely using MS Teams video conference should contact Ms. Coldiron at least two business days before the scheduled public hearing to request an invitation for the MS Teams. To request that the tentatively scheduled hearing be held, a written request must be filed with the AOGCC no later than 4:30 p.m. on December 23, 2024. If a request for a hearing is not timely filed, the AOGCC may issue an order without a hearing. To learn if the AOGCC will hold the hearing, call (907) 793-1223 after December 24, 2025. In addition, written comments regarding this application may be submitted to the AOGCC, at 333 west 7th Avenue, Anchorage, AK 99501 or samantha.coldiron@alaska.gov. Comments must be received no later than 4:30 p.m. on January 9, 2025, except that, if a hearing is held, comments must be received no later than the conclusion of the January 16, 2025, hearing. If, because of a disability, special accommodations may be needed to comment or attend the hearing, contact Samantha Coldiron, at (907) 793-1223, no later than January 10, 2025. Jessie L.

Wilson Commissioner Commissioner Pub: Dec. 8, 2024 STATE OF ALASKA THIRD JUDICIAL DISTRICT ______________________________________2024-12-09 2026-08-04 Document Ref: JXPCO-REENW-Q4MLK-Q6ZQL Page 2 of 27 1 Hilcorp Alaska, LLC Walbert Schulpen Facilities Engineer, Endicott Post Office Box 244027 Anchorage, AK 99524-4027 November 22, 2024 Jim Regg, Supervisor, Inspections Alaska Oil and Gas Conservation Commission 333 West 7th Avenue, Suite 100 Anchorage, Alaska 99501 Re: Endicott Gas Sales to on Site Datacenter Dear Supervisor Regg, Hilcorp Alaska, LLC (HAK) is proposing a pilot project to demonstrate the feasibility of monetizing North Slope gas by data centers on the North Slope of Alaska. This pilot project is designed to be a material first step in a broader effort to monetize Alaska’s stranded natural gas resource. The small scale of the pilot (1.3 MMSCF/day) and short duration (4-5 years) require a non-traditional tailored approach to achieve project feasibility. The scope of this pilot project considers the sale of power generated using gas sourced from within the unit. The currently installed gas measurement system has been used in the gas disposition reporting of fuel gas for the turbines to the state. Hilcorp requests approval for using the existing power turbine gas measurement venturi meters, in combination with power measurement for custody transfer of gas to the datacenter for royalty payment purposes. The measurement system, as is, deviates from MPMS 14.14 because the thermowell is upstream, rather than downstream of the venturi flow meter. In addition, AGA flow computations are not carried out and a square root method is used instead. Hilcorp considers the proposed deviations acceptable due to the limited scale and duration of the project and is requesting AOGCC’s approval for these deviations. Any upfront changes to the measurement system would result in extensive delays to the start-up of the datacenter pilot project. If the project lasts beyond the proposed scope of 5 years, Hilcorp commits to bringing the system up to the MPMS 14.14 requirements by installing a thermowell downstream each venturi meter and transferring the flow computations to a dedicated Emerson Process ROC800 Series 2 flow computer. Relevant meter run information required by Guidance Bulletin 13-002 is included below and attached: General Information Contractually, Hilcorp will sell power to the customer. The amount of electricity used by the customer will be metered as well as the total amount of electricity produced by Hilcorp’s on-unit gas turbines. The total amount of gas consumed by the turbines will also be measured. To arrive Endicott Gas Sales to on Site Datacenter Page 2 of 11 at the volume of gas (“X”) which is utilized to generate power sold to the customer, Hilcorp will solve the following: Hilcorp believes this approach would be appropriate given that the gas is being used wholly within the Duck Island Unit for power generation and neither the gas (or power) will be transferred off-unit. Additionally, it is worth noting this project will utilize less than 0.15% of total produced gas, over a limited period (approximately 4-5 years). This project will entail installing a datacenter at Endicott SDI. The datacenter will be tied into a transformer. Power consumption of the datacenter will be measured locally. The location of the datacenter and power measurement is identified in Figure 1 below with the yellow circle: Figure 1. LocaƟon of Datacenter and local power measurement. Endicott uses 4 gas fired Ruston power turbines for its power generation. The power turbines are being fed through the High-Pressure fuel gas system. Expected flow rates are in the range of 0-2 MMSCF/day for each of the turbines. Each turbine uses a Daniel venturi style flow meter. HP Fuel gas temperature is approximately 95F, and pressure approximately 400 psig. Power generated by each of the turbines is measured and added up for total power generation. A recent analysis of HP fuel gas is attached in Appendix 1. The power generation is at MPI, see Figure 2 below. Endicott Gas Sales to on Site Datacenter Page 3 of 11 A P&ID of the measurement system is shown in Appendix 2. Hilcorp plans to carry out a fuel gas composition analysis and venturi meter inspections on an annual basis. Hilcorp plans conducting quarterly transmitter calibrations on the pressure differential, pressure, and temperature transmitters. Hilcorp endeavors to start powering the datacenter January 1st 2025. API MPMS The applicable standard for venturi flow measurement of natural gas is API MPMS 14.14. While the flow measurement generally complies with this standard, the system was not specifically designed in line with API MPMS 14.14. Flow calculations and pressure and temperature compensation is carried out in the DCS using a square root method. The applicable flow calculations are detailed in Appendix 3. Figure 2. LocaƟon of power generaƟon, power and gas measurement. Endicott Gas Sales to on Site Datacenter Page 4 of 11 Meter Run The venturi flow meter run consists of a straight length piping run 3 ft upstream and 3.5 ft downstream of the venturi. API MPMS 14.14 recommends using ASME MFC-3M or the manufactures specifications for upstream and downstream straight length requirements (Section 11 Meter run, item a/). The manufacturer specification refers to ASME MFC-3M, so this is the guidance used. The pipe consists of 2” Schedule XS (ID 1.7”). This corresponds to approximately 21D upstream straight lengths and 24D downstream straight lengths. The requirement with 2 or more 90 degree bends in the same plane is for a minimum of 10.5D upstream and 3D downstream. The requirement with two or more 90 degree bends in different planes is 21D upstream and 3D downstream. The meter run straight lengths comply with ASME MFC-3M (1985) requirements. Pressure and temperature compensation for all flow meters is by a central upstream pressure and temperature transmitter located upstream of the venturi meters. All of this equipment is indoors in a heated module, and little temperature fluctuation is expected within the modules. A datasheet for the Daniel venturi flowmeters is shown in Appendix 3. The Beta ratio is 0.52614 for each of the instruments. Hilcorp plans to do annual gas compositional analysis using the ASTM D1945-14(2019) procedure. Flow Computer The venturi flow meter calculations are carried out in the DCS. The FLOWCOMPA calculation block is used, in combination with COMPTERM from equation B to calculate a pressure and temperature compensated flowrate. Documentation for these equations is included in Appendix 4. Endicott Gas Sales to on Site Datacenter Page 5 of 11 Endicott Gas Sales to on Site Datacenter Page 6 of 11 The flow measurement instruments are not connected to a UPS. In case of a power outage, load will be shed to the datacenter. No situation is envisaged where power will be supplied to the datacenter while the main power turbines are all offline. Instrument/Meter Calibrations Hilcorp plans to carry out a fuel gas composition analysis on an annual basis. Hilcorp plans conducting quarterly transmitter calibrations on the pressure differential, pressure, and temperature transmitters. Equipment currently used in transmitter calibrations: 1) Fluke 725 Process Calibrator (Datasheet attached in Appendix 5) Endicott Gas Sales to on Site Datacenter Page 7 of 11 2) 475 HART communicator 3) Hydraulic hand pump and test gauge The calibration ranges, model and serial numbers for the pressure and temperature instrumentation are as follows: 1) TI-3365 Rosemount Model# 3144P-Serial# 00655103 0-200 DegF. 2) PI-3365 Rosemount Model# 3351-Serial# 2133159 0-1000 PSIG. Nameplates for the Daniel Venturi flow elements are shown below: Figure 3.

Nameplate for venturi for GTRB-E3-4504- FE-2816-D Model# 4280-AC The Venturi meter is a highly durable and reliable flow measurement device characterized by its lack of moving parts or sharp edges, which minimizes susceptibility to buildup and erosion. The venturi meters are in a clean service, minimizing any wear over time. Despite its robust design, periodic maintenance and inspection are essential to uphold its performance over time. Inspection and Maintenance Plan: 1. Inspection of Meter and Piping o The Venturi meter and its associated upstream and downstream piping will be inspected to confirm that internal surfaces are clean and free from coatings, particulate buildup, or extraneous materials. 2. Tap Hole Examination o The upstream and throat tap holes will be inspected for signs of wear, edge rounding, nicks, particulate inclusions, burrs, buildup, and other damage. Any anomalies will be recorded for further evaluation. 3. Documentation and Comparison o Physical deviations and irregularities will be recorded. Whenever possible, the internal surface and tap hole dimensions will be compared to the Venturi meter’s manufacturing datasheet. If deviations are observed, the meter’s manufacturer will be consulted to assess potential impacts on performance and to recommend appropriate cleaning or servicing procedures. Endicott Gas Sales to on Site Datacenter Page 10 of 11 Inspection Frequency: Hilcorp plans conducting venturi meter inspections on an annual basis. When it does not impact production or operations, this includes an internal inspection of the upstream meter run, and the flowmeter using borescope. Normally, Endicott uses 3 out of the 4 turbines to support production and operations, which would make the 4th turbine available for flow meter inspections. However, extra loads from drilling operations, for example, or planned or unplanned downtime of the turbines could cause all turbines to support ongoing operations or production. If this is the case, Hilcorp proposes to conduct the internal inspection as soon as it is feasible without production or operational downtime. Annex B of MPMS 14.14 will be used to capture the findings (Appendix 6). We request the AOGCC approve the method outline for measuring gas associated with the datacenter power sales at Endicott.

You are here: Reference > Control Builder Components Theory > Data Acquisition Functions > DATAACQ (Data Acquisition) Block > Insertion type functional characteristics-DATAACQ block Insertion type functional characteristics- DATAACQ block The following table summarizes the functional characteristics for a given insertion type. Insertion Type Function Process Variable Algorithm (PV_Alg)Provides the capability of performing a calculation on the fetched input value. The user-written algorithm must store the computed value into the process input value (P1). The configured parameter references in the CAB instance acquire inputs for the CAB program. The value placed in P1 goes through the rest of the processing namely PV characterization, filtering, PV source selection and alarm processing. The user-written CAB program stores the calculated value in P1 and must also store the status into parameter P1STS based on the value of P1. If the calculated value is NaN, the status is set to BAD. If calculated value is good, the status is set to Normal The CAB program should also handle the scenario where the input recovers from a BAD status. Note that the Page 1 of 3Experion User Assistance | Insertion type functional characteristics-DATAACQ block 9/27/2024file:///C:/Program%20Files%20(x86)/Honeywell/Experion%20PKS/User%20Assistance/C... Insertion Type Function value of P1STS can never be set to Manual or Uncertain, in a simple strategy. Post PV Characterization (Post_PVchar)Provides the capability of implementing a custom filtering function. The filtered value is stored in P1EU. You can also implement custom clamping and cutoff functions in a Post_PVchar insertion program. Another option is to use the built-in filtering value under certain process conditions by setting the parameter P1FILITINIT to TRUE (ON) in the CAB program. Post Clamping and Filtering (Post_Clampfilt) Provides the capability of implementing custom source selection strategies and bypass the built source selection. The final value is stored in PV. The CAB program should also set PVSTS, PVEXHIFL, and PVEXLOFL parameters to the appropriate states. Post PV Source (Post_PVsrc)Provides the capability of implementing custom PV calculations. The CAB program can also selectively enable or disable alarms based on process conditions. For example, if you need to disable the PV high alarm, the trip point for PV high alarm (PVHIALM.TP) is set to NaN in the insertion program and the PV high alarm will not be processed in the alarm processing routine Post Alarm Processing (Post_Alarmproc) Page 2 of 3Experion User Assistance | Insertion type functional characteristics-DATAACQ block 9/27/2024file:///C:/Program%20Files%20(x86)/Honeywell/Experion%20PKS/User%20Assistance/C... Insertion Type Function Provides the capability of modifying the built-in alarm processing. For example, selected alarms can be disabled in the next execution cycle by setting their trip points to NaN.

You are here: Reference > Control Builder Components Theory > Data Acquisition Functions > DATAACQ (Data Acquisition) Block > PV Characterization-DATAACQ block PV Characterization-DATAACQ block You can configure the PV Characterization option to have the DATAACQblock provide one of the following conversion functions. •LINEAR: Converts P1 to Engineering Units based on the 0 to 100 input span (100) and the configured PV span in Engineering Units (PVEUHI - PVEULO). The linear conversion is calculated as follows. P1EU (P1 /100)*(PVEUHI - PVEULO) + PVEULO where: P1 =Process input value from another block P1EU =P1 value in Engineering Units PVEUHI =User configured PV high range value in Engineering Units for 100% full scale PVEULO =User configured PV low range value in Engineering Units for 0% full scale 100 =Span for 0 to 100 input range For example, If you want to convert the P1 input to a range of 0 to 1200 degrees, configure PVEULO as “0” and PVEUHI as “1200”. In this case, if P1 input is 50%, P1EU equals (50 / 100)*(1200 - 0) + 0 or 0.5*1200 equals 600 degrees.

Then, converts the square root value to Engineering Units based on the configured PV span in Engineering Units (PVEUHI - PVEULO). The Square Root conversion is calculated as follows. •For P1 input greater than or equal to zero (0): P1EU SQRT (P1 /100) * (PVEUHI - PVEULO) + PVEULO •For P1 input less than zero (0): P1EU - (SQRT (-P1 /100)) * (PVEUHI - PVEULO) + PVEULO For example, If you want to convert the P1 input to a range of 0 to 1200 gallons per hour, configure PVEULO as “0” and PVEUHI as “1200”. In this case, if P1 input is 40%, P1EU equals the square root of (40 / 100) * (1200 - 0) + 0 or 0.632 * 1200 equals 758.4 gallons per hour. •NONE: Applies no conversion to the P1 input.

It looks like this graphically. Beginning with R520, a new functionality is added in the DATAACQ block which allows you to configure separate alarm description for each alarm type. This description is displayed as a process alarm description in the Experion Station. This functionality allows you to override the block “Description” (DESC) of any alarm type with a specific alarm description. Two new alarm parameters, Enable Description (ED) and Description (DESC) are added to each alarm type to support this functionality. See section Configuring Alarm Description to rewrite the description in the DATAACQ Block.

With R410, you can configure the on-delay time, off-delay time, deadband value, and deadband unit for the individual alarms. For example, you can use the following parameters to configure the on-delay time, off-delay time, deadband values, and deadband units for the PVHIALM parameter. •PVHIALM.TM •PVHIALM.TMO •PVHIALM.DB •PVHIALM.DBU The following parameters can be used for configuring the on-delay time and off- delay time for the BADPVALM, ROCPOSALM, and ROCNEGALM alarms. •BADPVALM.TM •BADPVALM.TMO •ROCPOSALM.TM •ROCPOSALM.TMO •ROCNEGALM.TM •ROCNEGALM.TMO Each DATAACQ block supports the following user configurable attributes. The following table lists the given name of the “Tab” in the parameter configuration form and then briefly describes the attributes associated with that Tab. This data is only provided as a quick document reference, since this same information is included in the on-line context sensitive Help. Configuration Tab Description Main •Name - Block (Tag) name of up to 16 characters long. Must be unique within the CM block containing it. •Description (DESC) - Block descriptor of up to 132 characters long. •Engineering Units (EUDESC) - Lets you specify a text string of up to 16 characters to identify the variable Page 2 of 11Experion User Assistance | DATAACQ (Data Acquisition) Block 9/27/2024file:///C:/Program%20Files%20(x86)/Honeywell/Experion%20PKS/User%20Assistance/C... Configuration Tab Description values associated with this block. For example, you could specify DEGF for temperature values in degrees Fahrenheit. This name is used on any associated displays and generated reports. •Execution Order in CM (ORDERINCM) - Specifies the execution order of the block in the CM relative to other blocks contained in this CM. Enter as a number between 1 to 32767. The default value is 10. Refer to the Function Block Execution Schedules section in the beginning of this document for more information. •PV Source Option (PVSRCOPT) - Lets you select whether you want to limit the PV source to AUTO only or allow other PV source selections. The default selection is ONLYAUTO. •PV Source (PVSOURCE) - Lets you select the source of the PV as SUB for a user program, MAN for an operator, or AUTO for process input connection. Only applicable with PV Source Option selection of ALL. The default selection is AUTO. •PV Format (PVFORMAT) - Lets you select the decimal format to be used to display the PV values. The selections are D0 for no decimal place (-XXXXXX.), D1 for one decimal place (-XXXXX.X), D2 for two decimal places (-XXXX.XX), and D3 for three decimal places (-XXX.XXX). The default selection is D1 for one decimal place. •PV Character (PVCHAR) - Lets you select whether or not you want to apply Linear or Square Root PV characterization conversion to the input (P1). The default selection is NONE, which means no characterization conversion is applied.

Configuration Tab Description •PVEU Range High (PVEUHI) - Lets you specify the high input range value in engineering units that represents 100% full scale PV input for the block. The default value is 100. •PVEU Range Low (PVEULO) - Lets you specify the low input range value in engineering units that represents the 0 full scale PV input for the block. The default value is 0 (zero). •PV Limits Hi (PVEXHILM) - Lets you specify a high limit value for the PV in engineering units. If the PV value exceeds this limit, the block clamps the PV to the limit value and sets the PV high limit flag (PVEXHIFL). The default value is 102.9. •PV Limits Low (PVEXLOLM) - Lets you specify a low limit value for the PV in engineering units. If the PV value falls below this limit, the block clamps the PV to the limit value and sets the PV low limit flag (PVEXLOFL). The default value is -2.9. •Low Signal Cut Off (LOCUTOFF) - - Lets you specify the low signal cutoff limit for the P1 input after filtering and clamping. When PVAUTO is below the limit, the block sets the PVAUTO value to the PVEULO value. Only applicable with PV character selection of Linear or Square Root. The default value is NaN (Not- a-Number), which means there is no cutoff limit. •Clamping Option (P1CLAMPOPT) - Lets you specify whether or not you want P1 to be clamped within the PV high (PVEXHILM) and low (PVEXLOLM) limits. The default setting is DISABLE, which means no clamping is applied. •Lag Time (P1FILTTIME) - Lets you specify a first order filter time in minutes for the P1 input. When time is Page 4 of 11Experion User Assistance | DATAACQ (Data Acquisition) Block 9/27/2024file:///C:/Program%20Files%20(x86)/Honeywell/Experion%20PKS/User%20Assistance/C... Configuration Tab Description non-zero (1 to 1440 minutes), a first-order filter is applied to P1EU and the result is stored in an intermediate parameter called FilteredP1 (not a visible parameter). As long as FilteredP1 is within PV limits, it is copied to PVAUTO. See Input Filtering in this section for more details. The default value is 0. Alarms •Alarm Limits - Identifies the types of alarms this block supports. Of course, these alarms also interact with other block configuration values such as PVEU Range Hi and PVEU Range Lo. The types are: •PV High High (PVHHALM.FL •PV High (PVHIALM.FL) •PV Low (PVLOALM.FL) •PV Low Low (PVLLALM.FL) •Positive Rate of Change (ROCPOSALM.FL) •Negative Rate of Change (ROCNEGALM.FL) •Bad PV (BADPVALM.FL) •High Significant Change (PVHISIGCHG.TP) •Low Significant Change (PVLOSIGCHG.TP) •Trip Point - Lets you specify the following trip points for the given alarm. The default value is NaN, which disables the trip point. •PVHHALM.TP (PV High High Alarm Trip Point) •PVHIALM.TP (PV High Alarm Trip Point •PVLOALM.TP (PV Low Alarm Trip Point) •PVLLALM.TP (PV Low Low Alarm Trip Point) Page 5 of 11Experion User Assistance | DATAACQ (Data Acquisition) Block 9/27/2024file:///C:/Program%20Files%20(x86)/Honeywell/Experion%20PKS/User%20Assistance/C... Configuration Tab Description •ROCPOSALM.TP (Positive Rate of Change Alarm Trip Point) •ROCNEGALM.TP (Negative Rate of Change Alarm Trip Point) •PVHISIGCHG.TP (High Significant Change Alarm Trip Point) •PVLOSIGCHG.TP TP (Low Significant Change Alarm Trip Point) •Priority - Lets you set the desired priority level individually for each alarm type (PVHHALM.PR, PVHIALM.PR, PVLOALM.PR, PVLLALM.PR, ROCPOSALM.PR, ROCNEGALM.PR, and BADPVALM.PR). The default value is LOW. The levels are: •NONE - Alarm is neither reported nor annunciated. •JOURNAL - Alarm is logged but it does not appear on the Alarm Summary display. •LOW, HIGH, URGENT - Alarm is annunciated and appears on the Alarm Summary display. •Severity - Lets you assign a relative severity individually for each alarm type (PVHHALM.SV, PVHIALM.SV, PVLOALM.SV, PVLLALM.SV, ROCPOSALM.SV, ROCNEGALM.SV, and BADPVALM.SV) as a number between 0 to 15, with 15 being the most severe. This determines the alarm processing order relative to other alarms. The default value is 0. •Deadband Value (ALMDB/xxxxALM.DB) - Defines the minimum value that needs to be added to or subtracted from the trip point before reporting an Page 6 of 11Experion User Assistance | DATAACQ (Data Acquisition) Block 9/27/2024file:///C:/Program%20Files%20(x86)/Honeywell/Experion%20PKS/User%20Assistance/C... Configuration Tab Description RTN. By specifying a deadband value, you can prevent the nuisance alarms due to noise at values near the trip point. The default value is 1. For a high alarm, RTN is reported only when the OP value is less than the trip point - deadband value. For a low alarm, RTN is reported only when the OP value is more than the trip point + deadband value. Prior to R410, once the deadband value was configured, this value was loaded to the individual alarm parameters (for example, PVHIALM.DB and PVLOALM.DB) when the CM was loaded. If you configured the individual alarm parameters as Monitoring Parameters for the block, you could change the individual alarm value while monitoring the loaded block in CB. With R410, the deadband value can be individually configured for each alarm. For example, you can configure PVHIALM.DB as 5 and PVLOALM.DB as 3. However, if you are migrating from pre-R410 to later releases, refer to Impact of migration on alarm attributes. •Filter Time (ALMTM/xxxxALM.TM) - Defines the duration in seconds during which a process alarm reporting is suppressed. This helps in preventing the nuisance alarms from being reported repeatedly during the process upset and improves the efficiency of the operator. Once you configure this value for an alarm, the alarm is reported on the Station only if the alarm condition continues to exist even after this value expires. The default time is 0; that is the alarm is reported as soon as the alarm condition occurs. Page 7 of 11Experion User Assistance | DATAACQ (Data Acquisition) Block 9/27/2024file:///C:/Program%20Files%20(x86)/Honeywell/Experion%20PKS/User%20Assistance/C... Configuration Tab Description Prior to R410, once configured, this value was loaded to the individual alarm parameters (for example, PVHIALM.TM and PVLOALM.TM) when the CM was loaded. If you configured the individual alarm parameters as Monitoring parameters for the block, you could change the individual alarm value while monitoring the loaded block in CB. With R410, the filter time can be individually configured for each alarm. If the configured filter time is more than 9999 seconds, the values are clamped. For example, you can configure PVHIALM.TM as 5 seconds and PVLOALM.TM as 3 seconds. However, if you are migrating from pre-R410 to later releases, refer to Impact of migration on alarm attributes. •Deadband Units (ALMDBU/xxxx.ALMDBU) - Defines the unit for the deadband value - percent or engineering units. The default value is percent. Prior to R410, once configured, this value was loaded to the individual alarm parameters (for example, PVHIALM.DBU and PVLOALM.DBU) when the CM was loaded. If you configured the individual alarm parameters as Monitoring parameters for the block, you could change the individual alarm value while monitoring the loaded block in CB. With R410, the deadband unit can be individually configured for each alarm. For example, you can configure PVHIALM.DBU as percent and PVLOALM.DBU as EU. However, if you are migrating from pre-R410 to later releases, refer to Impact of migration on alarm attributes. •Off-delay Time (xxxxALM.TMO) - Defines the duration in seconds during which an RTN reporting is Page 8 of 11Experion User Assistance | DATAACQ (Data Acquisition) Block 9/27/2024file:///C:/Program%20Files%20(x86)/Honeywell/Experion%20PKS/User%20Assistance/C... Configuration Tab Description suppressed even though the alarm condition does not exist. The RTN is reported on the Station only after this time expires and the alarm condition has returned to normal. The default time is 0; that is RTN is reported as soon as the alarm condition returns to normal. If a deadband value is also configured, the RTN is reported only when the OP value is less than the trip point - deadband for the configured Off-delay time. However, if you are migrating from pre-R410 to later releases, the alarm off-delay time will be set as default value (0). •Alarm Description: You can configure two parameters, Enable Description (ED) and Description (DESC) for each alarm type under the “Alarm Description”. You must enable override alarm description checkbox to write the alarm description for the respective alarm type. If it is disabled, the ‘block description’ (DESC) is considered as the alarm description. See section Configuring Alarm Description to rewrite the description in the DATAACQ Block.

You are here: Alarm processing-DATAACQ block The DATAACQ block may be configured to generate an alarm when PV exceeds one of the following trip points for more than a specified time: •PV High trip point (PVHIALM.TP) - if PV exceeds this trip point for more than PVHIALM.TM seconds, a PV High alarm is generated and the PV High alarm flag (PVHIALM.FL) is set. PV High alarming is enabled by setting PVHIALM.TP to a value which is not IEENaN, and disables it by setting PVHIALM.TP = NaN. PVHIALM.TP must be <= PVHHALM.TP. •PV High High trip point (PVHHALM.TP) - if PV exceeds this trip point for more than PVHHALM.TM seconds, a PV High High alarm is generated and the PV High High alarm flag (PVHHALM.FL) is set. PV High High alarming is enabled by setting PVHHALM.TP to a value which is not IEENaN, and disabled by setting PVHHALM.TP = NaN. PVHHALM.TP must be <= PVEUHI. •PV Low trip point (PVLOALM.TP) - if PV falls below this trip point for more than PVLOALM.TM seconds, a PV Low alarm is generated and the PV Low alarm flag (PVLOALM.FL) is set. PV Low alarming is enabled by setting PVLOALM.TP to a value which is not IEENaN, and disabled by setting PVLOALM.TP = NaN. PVLOALM.TP must be >= PVLLALM.TP. •PV Low Low trip point (PVLLALM.TP) - if PV falls below this trip point for more than PVLLALM.TM seconds, a PV Low Low alarm is generated and the PV Low Low alarm flag (PVLLALM.FL) is set. Page 1 of 3Experion User Assistance | Alarm processing-DATAACQ block 9/27/2024file:///C:/Program%20Files%20(x86)/Honeywell/Experion%20PKS/User%20Assistance/C... PV Low Low alarming is enabled by setting PVLLALM.TP to a value which is not IEENaN, and disabled by setting PVLLALM.TP = NaN. •Positive Rate-of-Change trip point (ROCPOSALM.TP) - The rate-of-change trip point is specified by the user as EUs per minute, and the function block converts this to EUs per 4-second period. If PV changes in a positive direction by more than this amount for two consecutive 4-second periods, the function block will generate a Positive Rate-of-Change alarm and set the Positive Rate-of-Change alarm flag (ROCPOSALM.FL). Positive Rate-of-Change alarming is enabled by setting ROCPOSALM.TP> = 0, and disabled by setting ROCPOSALM.TP = NaN. ATTENTION: •The rate-of-change trip point is specified in EUs per minute. •ROCPOSALM.TP is expressed as a positive number in EUs per minute. •Negative Rate-of-Change trip point (ROCNEGALM.TP) - The Rate-of- Change trip point is specified by the user in EUs per minute, and the function block converts this to EUs per 4-second period. If PV changes in a negative direction by more than this amount for two consecutive periods, the function block will generate a Negative Rate-of-Change alarm and set a Negative Rate-of-Change alarm flag (ROCPOSALM.FL). Negative Rate-of-Change alarming is enabled by setting ROCNEGALM.TP> =0, and disabled by setting ROCNEGALM.TP = NaN. ATTENTION: •The rate-of-change trip point is specified in EUs per minute. •ROCNEGALM.TP is expressed as a positive number in EUs per minute. The following parameters also apply to each of the previously specified alarms: Page 2 of 3Experion User Assistance | Alarm processing-DATAACQ block 9/27/2024file:///C:/Program%20Files%20(x86)/Honeywell/Experion%20PKS/User%20Assistance/C... •Alarm Filter Time (PVHIALM.TM, PVHHALM.TM, etc.) - Prevents input spikes from causing alarms. PV will only be alarmed if it consistently exceeds the trip point for more than xxxALM.TM seconds. If xxxALM.TM = 0, the function block will generate an alarm as soon as PV exceeds the trip point. Note: This parameter does not apply to the Rate-of-Change alarms (i.e., there is no ROCNEGALM.TM or ROCPOSALM.TM parameter). •Alarm Deadband Value (PVHIALM.DB, PVHHALM.DB, etc.) - Note that alarm deadband is not supported for Rate-of-Change alarms. Prevents recurring alarms and returns-to-normal due to a noise when PV is near the trip point. The deadband is applied to the return-to-normal. For example, if PV is in high alarm (PVHIALM.FL = On), it must return to a value of PVHIALM.DB below the high trip point before it is considered “normal”; and if it is in low alarm, it must return to a value of PVLOALM.DB above the low trip point. •Alarm deadband units (PVHIALM.DBU, PVHHALM.DBU, etc.) - Indicates if the corresponding alarm deadband (xxxALM.DB) is in percent or engineering units. This parameter does not apply to Rate-of-Change alarms (i.e., there is no ROCNEGALM.DBU or ROCPOSALM.DBU parameter). For Rate-of-Change alarms, the deadband is always expressed in EUs/minute. •Alarm flag (PVHIALM.FL, PVHHALM.FL, ROCNEGALM.FL, etc.) - Indicates if the corresponding alarm condition exists. •Alarm priority (PVHIALM.PR, PVHHALM.PR, ROCNEGALM.FL, etc.) - Indicates the relative priority of the alarm. •Alarm severity (PVHIALM.SV, PVHHALM.SV, ROCNEGALM.SV, etc.) - Indicates the relative severity of the alarm (from 0 to 15).

If filtering is not configured, then P1CLAMPOPT is used to clamp P1 as follows: •If P1CLAMPOPT = Enable, the block clamps the filtered P1 to the PV limits and stores the result in PVAUTO. If the filtered input is outside the PV limits: •P1 = Actual input value •P1STS = Normal •PVAUTO = Exceeded limit •PVAUTOSTS = Uncertain (because the value was clamped) •Appropriate “limit exceeded” flag is set (PVEXHIFL or PVEXLOFL) •If P1CLAMPOPT = Disable and the filtered P1 is outside the limits, the block sets PVAUTO to Bad.
