Gas Quality Determination Sample Clauses

The Gas Quality Determination clause defines the standards and procedures for assessing whether delivered gas meets specified quality requirements. It typically outlines the testing methods, frequency of sampling, and the party responsible for conducting the analysis, such as using industry-standard laboratories or on-site equipment. This clause ensures that only gas meeting agreed-upon specifications is accepted, thereby protecting both parties from issues related to off-specification gas and maintaining the integrity of downstream operations.
Gas Quality Determination. Tests for oxygen, carbon dioxide, sulphur, and hydrogen sulphide content of the Gas delivered hereunder shall be made as often as deemed necessary by Gatherer, by means commonly used and accepted in the industry. Gas Analysis Samples shall be taken by Gatherer at the time of meter inspection and verification or at more frequent periods as agreed. These samples shall be used to determine the heating value and specific gravity to be used in computations in the measurement of Gas until the next regular test, or until changed by special test. For the purpose of determining initial heating value, all BTUs determined shall be based upon dry water vapor content at the same base pressure and base temperature conditions. No heating value will be credited for BTU’s attributable to hydrogen sulphide or other non- hydrocarbon components. All heating values must be applied to the calculated volumes at the same base pressure. Any adjustments to MMBTU or quality based on water vapor condition shall be performed as outlined in the “Water Vapor Correction” section in the Standards for Gas Measurement Computations in this document. Unless otherwise supported by a representative extended Gas analysis, Gatherer shall assume that C6+ components from a Gas analysis sample are broken down as follows: 60% normal Hexane, 30% normal Heptane, and 10% normal Octane. Gatherer shall sample and determine the gross heating value, relative density and compressibility by utilizing the latest edition of the following industry standards: 4.1 Gas Processors Association (GPA) 2166, Obtaining Natural Gas Samples for Analysis by Gas 4.2 Gas Processors Association (GPA) 2261, Analysis for Natural Gas and Similar Gaseous Mixtures by Gas Chromatography. 4.3 Gas Processors Association (GPA) 2145, Physical Constants for Paraffin Hydrocarbons and Other Components of Natural Gas. 4.4 Gas Processors Association (GPA) 2172, Calculation of Gross Heating Value, Relative Density, and Compressibility of Natural Gas Mixtures from Compositional Analysis. 4.5 American Gas Association Report Number 8 (AGA8), Compressibility Factors of Natural Gas and Other Related Hydrocarbon Gases. Gatherer shall sample the flowing Gas stream utilizing one of the following methods: 4.6 On-line Chromatography - If this method is utilized, an industry accepted gas chromatograph with full audit and error logging must be used, and maintained and calibrated by qualified personnel. 4.7 Accumulated Sample (also known as Composite Samp...
Gas Quality Determination. (a) All Gas and Injected Liquids tests conducted pursuant to this Agreement, whether by Gatherer or Shipper (or their respective representatives, shall be based on the applicable standards and specifications published in the American Gas Association (“AGA”) Committee Reports, the AGA Gas Measurement Manual, the MPMS, the Gas Processors Association (“GSPA”) Technical Standards, the GSPA Plant Operations Test Manual, and the American Society for Testing Materials StandardsSection 5, in each case, as amended from time to time. Specifically, as related to (i) Gas sampling techniques, the Parties (or their respective representatives) shall utilize GSPA Standard 2166-86, and (ii) Injected Liquids sampling techniques, the Parties (or their respective representatives) shall utilize GSPA Standard 2174-93, in each case, as amended from time to time, for obtaining Receipt Point Gas and Injected Liquids samples hereunder. (b) Semi-annually, or as often as Gatherer deems advisable, Gatherer shall obtain a representative sample of Shipper Gas and Shipper Injected Liquids at each Receipt Point and, by a chromatographic gas analysis, determine the test content and Gross Heating Value of such Shipper Gas and Shipper Injected Liquids. The first such determination shall be made within a reasonable time after delivery of Gas and Injected Liquids into the Gathering System begins hereunder, with such time not to exceed 30 Days, and shall apply until the first Day of the Month following the next determination. The period for determination shall be selected by Gatherer. Gatherer shall notify Shipper in writing of the date of taking the test. Shipper may witness the tests or make joint tests with its own appliances at Shipper’s sole cost. The Gas and Injected Liquids used in the content tests shall be measured in Standard Cubic Feet. The specific gravity of the Gas and Injected Liquids tested shall be determined by any method adopted as standard by the GSPA. The percentage of hydrogen sulfide in the Gas and Injected Liquids shall be determined by the GSPA Length of Stain Tube Method, or any other generally accepted industry method should the Length of Stain Tube Method be changed. Use of a chromatographic gas analysis will provide the composition of the remaining components in the Gas and Injected Liquids stream. For all Gas and Injected Liquids analyses contemplated hereunder, Gatherer shall have the right, but not the obligation, to change methods to meet recent industry stan...
