Common use of Additional Facilities Clause in Contracts

Additional Facilities. Upon Owner’s delivery of Gas utilizing at least seventy five percent (75%) of the existing compression facilities and if either; a) Owner is actively drilling and completing additional xxxxx, or b) current production is inclining at a sufficient rate, then Gatherer shall diligently pursue installation of additional gathering and compression facilities, in reasonable increments, up to the MDQ. If, after Owner is producing and delivering the MDQ into Gatherer's facilities, Gatherer in its sole discretion determines it is uneconomic, for any reason, to provide additional gathering and compression facilities for gas in excess of the MDQ, Gatherer shall provide Owner thirty (30) days notice of same. Owner and Gatherer will negotiate the terms and conditions under which Gatherer will expand the gathering and compression facilities. If the parties agree upon such terms, Gatherer shall diligently proceed with the installation of the agreed additional gathering and compression facilities. If the parties are unable to agree upon those terms and conditions within thirty (30) days following Gatherer’s notification, then the affected xxxxx shall, at Owner's option, be released from dedication under this Agreement. At the terminus of the Fort Union Gathering Header: 1. Wyoming Interstate Company, Ltd. - Medicine Bow Meter Station 2. Colorado Interstate Gas Company- North Platte River Station 3. KN Energy, Inc. - KNI Interconnect Station Except as otherwise agreed by Gatherer, the metering facilities to measure the volumes of Gas delivered at each Measurement Point and Delivery Point shall be maintained and operated or caused to be maintained and operated by Gatherer or Gatherer's designee. The Btu content of the Gas shall be determined by the facilities at the Receipt Points and Delivery Points. Such facilities and measurement data with respect to the Gas covered hereby shall at all reasonable times be subject to joint inspection by the parties hereto. Gas volumes measured with the use of orifice meter(s) shall be determined in accordance with the provisions of the Gas Measurement Committee Report No. 3 of the American Gas Association (ANSI/API 2530-1991) as amended, supplemented, or revised from time to time. Gas volumes measured with the use of positive or turbine meter(s) shall be determined on the basis of Gas Measurement Committee Report No. 7 of the American Gas Association as amended, supplemented, or revised from time to time. Gas volumes measured with the use of ultrasonic meter(s) shall be determined on the basis of Gas Measurement Committee Report No. 9 of the American Gas Association as amended, supplemented, or revised from time to time. The unit of volume for measurement of Gas delivered hereunder shall be one (1) cubic foot of Gas at a base temperature of sixty degrees Fahrenheit (60F.) and at an absolute pressure of fourteen and seventy-three one hundredths (14.73) pounds per square inch absolute. Atmospheric pressure for each of the Receipt Points and Delivery Points shall be assumed to be 12.7 psia irrespective of the actual atmospheric pressure at such points from time to time. Temperature shall be determined by a recording thermometer of standard make. If recording charts are used the arithmetical average of the temperature recorded during periods of flow for each chart, the factor for specific gravity according to the latest test therefor, and the correction for deviation from Ideal Gas Laws applicable during each chart period shall be used to make proper computations of volumes hereunder. If electronic flow measurement is used, continuous temperature, static pressure and differential pressure monitoring will be applicable. If electronic measurement is used in conjunction with on-site chromatograph, continuous monitoring of specific gravity will be applicable; otherwise the volumes computed using a fixed value specific gravity factor shall be corrected to reflect the actual specific gravity of the flowing Gas as determined by a chromatographic analysis of the sample accumulated during the same period of flow or, in the case of spot samples, the specific gravity factor determined by chromatographic analysis shall be applied to volumes delivered during the succeeding chart periods. The correction for deviation from the Ideal Gas Laws shall be computed and applied to volumes calculated by electronic measurement devices. Specific gravity and Btu shall be determined by such methods as may be developed by Gatherer through use of a continuous Gas sample accumulator, on premises analysis, or by spot samples taken at the Receipt Points and Delivery Points at intervals determined to be appropriate by Gatherer. Results from a continuous sampler shall be used to calculate volumes delivered during the same period in which the sample was accumulated; provided, however, that Gatherer reserves the right to adopt the practice of using the Btu content measured for a period prior to the Month of Gas flow in calculating the quantity of Gas transported during a given Month. Results from a spot sample shall be used to calculate volumes during the subsequent period until another sample is taken. The arithmetical average of the continuous temperature recorded during each chart period, the factor for specific gravity according to the latest test therefor, and the correction for deviation from Ideal Gas Laws applicable during each chart period shall be used to make proper computations of volumes hereunder.

The volume of Gas measured shall be multiplied by the applicable Btu content for such Gas (either that measured for the Month of Gas flow or for the designated period of Btu measurement that may occur prior to the actual Month of Gas flow) to determine the total volume of Gas in MMBtu.
