API RP 80-2020 pdf download.Defnition of Onshore Gas Gathering Lines.
1 Scope This industry standard provides a functional description of onshore natural gas gathering pipelines for the sole purpose of providing users with a practical guide for determining the application of gas gathering in the federal Gas Pipeline Safety Standards, 49 CFR Part 192, and state programs implementing these standards. Because of the regional and operational diversity within the natural gas industry, additional guidance is necessary to ensure appropriate and consistent application of the gas gathering line defnition. This document does not apply to transportation-related underground gas storage facilities. 2 Normative References There are no normative references in this document. 3 Terms, Defnitions, Acronyms, and Abbreviations 3.1 Terms and Defnitions For the purposes of this document, the following defnitions apply. 3.1.1 commingle To combine the hydrocarbon streams from two or more wells, units, felds, production zones, or production facilities through a series of pipelines for processing, treatment, and/or delivery to an end user or another pipeline. 3.1.2 extraction and recovery Operations used to move liquid and/or gas products from an underground reservoir to the surface. 3.1.3 gathering line gas treatment facility One or a series of gas treatment operations on a gathering line operated for the purpose of removing impurities. 3.1.4 lifting Refers to mechanical and other means used to move liquid and/or products from the producing interval in the well to the surface. 3.1.5 measurement The process of gauging or determining the quantity of hydrocarbons. 3.1.6 natural gas processing plant A natural gas processing operation, other than production processing, operated for the purpose of commercially extracting one or more components, such as natural gas liquids, carbon dioxide, sulfur, or helium from the gas stream.
3.1.8 production compression Compression used to boost line pressures on the discharge, lower line pressures on the suction, and/or increase production by lowering wellhead pressures. 3.1.9 production feld feld An area that is underlain by at least one reservoir containing natural gas or natural gas associated with crude oil. 3.1.10 production piping Includes individual well fowlines, equipment piping, transfer lines between production operation equipment elements and sites, and tie-in lines to connect to gathering, transmission, or distribution lines. 3.1.11 production processing A natural gas processing operation for the recovery of natural gas liquids from the gas, and that is limited to situations in which: a) there is no custody transfer of the gas, from production through processing and residue return; b) there have been no intermediate production operations between the well and the processing facility; and c) all residue gas goes back into the production and/or production support operations as fuel, gas lift operations, and/or injection. 3.1.12 residue gas The gas remaining after processing at a natural gas processing plant. 3.1.13 separation The physical and/or chemical technique used to segregate a production stream (oil, water, gas). 3.1.14 stabilization The treatment, by chemical, thermal, mechanical, and/or other means, of produced fuids that removes portions of dissolved gases and other light constituents, typically intended to lower the vapor pressure. 3.1.15 storage Above-ground containment of liquids associated with oil and gas production operations. 3.1.16 treatment The physical and/or chemical technique used to enhance separation of produced well fuids and removal of impurities using equipment such as iron sponge units, feld amine units, and dehydrators. 4 Gathering Lines 4.1 General Discussion The defnition of a gathering line is based on the function performed by that pipeline.
4.2 Defnition of Onshore Gathering Line A “gathering line” is defned as any pipeline or part of a connected series of pipelines used to: — transport gas from the furthermost downstream point in a production operation to the furthermost downstream of the following end points, which physically may have intermediate deliveries that are not necessarily part of the gathering line: 1) the inlet of the frst downstream natural gas processing plant, other than a natural gas processing plant located on a transmission line, unless the operator can demonstrate, using sound engineering principles, that gathering extends to a further downstream plant (see Figure 1); 2) the outlet of the furthermost downstream gathering line gas treatment facility; 3) the furthermost downstream point where gas produced in the same production feld or separate production felds not more than 50 miles from each other, is commingled, unless the authorities having jurisdiction permit a longer separation distance; 4) the outlet of the furthermost downstream compressor station used to increase gathering line pressure for delivery to another pipeline; or
