2、3REAFFIRMED,MARCH 2015 SPECIAL NOTES API publications necessarily address problems of a general nature.With respect to partic-ular circumstances,local,state,and federal laws and regulations should be reviewed.API is not undertaking to meet the duties of employers,manufacturers,or suppliers towarn an
3、d properly train and equip their employees,and others exposed,concerning healthand safety risks and precautions,nor undertaking their obligations under local,state,or fed-eral laws.Information concerning safety and health risks and proper precautions with respect to par-ticular materials and conditi
4、ons should be obtained from the employer,the manufacturer orsupplier of that material,or the material safety data sheet.Nothing contained in any API publication is to be construed as granting any right,byimplication or otherwise,for the manufacture,sale,or use of any method,apparatus,or prod-uct cov
5、ered by letters patent.Neither should anything contained in the publication be con-strued as insuring anyone against liability for infringement of letters patent.Generally,API standards are reviewed and revised,reaffirmed,or withdrawn at least everyfive years.Sometimes a one-time extension of up to
6、two years will be added to this reviewcycle.This publication will no longer be in effect five years after its publication date as anoperative API standard or,where an extension has been granted,upon republication.Statusof the publication can be ascertained from the API Standards department telephone
7、(202)682-8000.A catalog of API publications,programs and services is published annually andupdated biannually by API,and available through Global Engineering Documents,15 Inv-erness Way East,M/S C303B,Englewood,CO 80112-5776.This document was produced under API standardization procedures that ensure
8、 appropri-ate notification and participation in the developmental process and is designated as an APIstandard.Questions concerning the interpretation of the content of this standard or com-ments and questions concerning the procedures under which this standard was developedshould be directed in writ

14、RPs for the design of gas lift systems.Other API Specifications,API RPs,and Gas Processors Suppliers Association(GPSA)documents are referenced andshould be used for assistance in design and operation.Introduction to Gas Lift System Design and Performance Prediction API RP 11V8 Recommended Practice f
15、or Gas Lift System Design and Performance Pre-diction,provides two functions:A broad overview of gas lift systems and various major types of gas lift operations.Recommended practices for gas lift system design and for modeling methods used inperformance prediction.All key system components are revie
16、wed to provide guidancefor engineers,technicians,well analysts,and operating personnel who are involved ingas lift system analysis,troubleshooting,design,and optimization.The primary purpose of this API Recommended Practice(RP)is to emphasize gas lift as asystem and to discuss methods used to predict its performance.Information must be gath-ered and models validated prior to a system design,which must precede wellbore gas liftmandrel and valve design.The subsurface and surface components of the
