by: Martinez, John; Dunham, Cleon — Added 4/16/2008 12:00:00 AMGeneral - API, ISO Gas-Lift


This presentation will highlight the purpose of

Existing documents: API Specification 11V1 – Gas lift valves, orifices, dummies, API Recommended Practice (RP) 11V2 – Gas lift valve testing, modeling, API RP 11V5 – Gas lift operations (revision in progress), API RP 11V6 – Gas lift design, API RP 11V7 – Gas lift valve reconditioning, and API RP 11V8 – Gas lift systems;

Documents under development: API RP 11V9 – Dual gas lift and API RP 11V10 – Intermittent gas lift

and how they can be obtained and used to facilitate training and best practices in oil and gas production companies.

API RP 90 – Recommended Practice for Annular Casing Pressure Management for Offshore Wells
by: Parker, Wanda June — Added 3/31/2009 12:00:00 AMGeneral - API, ISO Gas-Lift


In August 2006, API published the first addition of RP 90, API Recommended Practice, Annular Casing Pressure. This RP was developed in response to a draft rulemaking published by MMS in 2001 regarding annular pressure in wells located on the OCS. MMS is currently reviewing the RP for incorporation into the Code of Federal Regulations. This presentation will be an overview of the recommended practice and its development.

API Standards Overview
by: Goodman, Roland — Added 7/1/2009 12:00:00 AMGeneral - API, ISO Gas-Lift


This presentation will cover API's standards program, including its history, mission, and role in the U.S. oil and natural gas industry. An overview of API's standards development process, standards committee structure, and international standards activities will be provided as well.

IPO Gas-Lift Design Using Valve Performance
by: Decker, Ken — Added 3/29/2009 12:00:00 AMGeneral - API, ISO Gas-Lift


Gas-lift design has been practiced for many years using the Thornhill/Craver (T/C) equation to predict the amount of gas passage for a particular port size. This practice has been fairly successful but, the T/C equation and chart was never intended for use with live gas-lift valves.

Valve performance is much better understood now and methods are available to accurately predict gas-lift valve flow passage. To date, a design technique has not been provided for the use of this information during the design stage. It is the purpose of this presentation to provide that technique.

ISO Document Development Process
by: Bijkhuis, Bert — Added 7/1/2009 12:00:00 AMGeneral - API, ISO Gas-Lift


The International Standards Organisation (ISO) strives to issue standards with a worldwide acceptance. To achieve such a widespread use of ISO standards, participating countries introduce completed and approved standards into their national regulations through their national standard organisations.

ISO is organised in Technical Committees (TC) covering specific areas. As these areas themselves are quite wide, a further division in Subcommittees (SC) and working groups (WG) has been established. This is done to fence off working fields that can be handled by a specific group of experts. Sometimes working groups (WG) are supported by task groups (TG) preparing standards on specific equipment items.

Approved standards are published as International standards (IS) by the ISO central secretariat (CS) in Geneva, Switzerland.

ISO is supported by 157 member countries in three categories (member bodies, correspondent members, subscriber members). Member countries are participating in a

ISO Gas-Lift Standards
by: Dunham, Cleon — Added 4/22/2008 12:00:00 AMGeneral - API, ISO Gas-Lift


The International Organization for Standards (ISO) is producing gas-lift standards for the gas-lift industry. Currently, four standards are being developed:

• ISO 17078.1 – Side-pocket mandrels. Published by ISO in Dec. 2004.

• ISO 17078.2 – Flow control devices for side-pocket mandrels. First draft completed; starting international review process.

• ISO 17078.3 – Running, pulling, and kick-over tools, and latches for side-pocket mandrels. Being drafted.

• ISO 17078.4 – Practices for side-pocket mandrels and related equipment. Being drafted.

The existence of these standards will:

• Permit the user/purchaser to specify the equipment quality that is required for each specific application.

• Be assured that each piece of equipment is manufactured and tested according to specific requirements.

• Assure that new equipment suppliers who claim to meet these standards are required to demonstrate compliance with these standards.

Update on API and ISO Gas-Lift Standards and Recommended Practices
by: Dunham, Cleon; Hall, Jim; Mabry, Wayne — Added 3/31/2009 12:00:00 AMGeneral - API, ISO Gas-Lift


The API 11V and ISO 17078 Task Groups develop standards and recommended practices for gas-lift.

API 11V Gas-Lift Task Group. The API Task Group recently approved two documents for submission to API Committee 11 for publication.

ISO 17078 Gas-Lift Task Group. The ISO 17078 Gas-Lift Task Group has completed work on four International Standards.
