ISO 17078-2:2007

Overview

ISO 17078-2:2007 - Petroleum and natural gas industries - Drilling and production equipment - Part 2: Flow-control devices for side-pocket mandrels - defines requirements for subsurface flow-control devices used in side-pocket mandrels. The standard covers specification, selection, design, manufacture, quality control, testing, calibration and shipping preparation for these devices in the global petroleum and natural gas industry. It also provides performance testing and calibration guidance. Installation, retrieval and reconditioning of used devices are explicitly outside its scope.

Key topics and technical requirements

• Functional and technical specification: functional characteristics, well and operational parameters, compatibility with well equipment, environmental service classes, and allowable design changes.
• Design validation and testing grades: a tiered approach (multiple design validation grades and product functional testing grades) lets purchasers specify the level of validation and testing needed for a given application.
• Quality control and supplier requirements: documentation, part identification, QC procedures, heat treatment and welding qualifications, non‑destructive examination, and shipping/storage preparation.
• Performance testing and calibration: includes dynamic flow testing, flow coefficient calculation, back‑check, opening/closing pressure testing, bellows life cycle, erosion, leakage and probe/travel tests - many described in normative annexes.
• Environmental service classes: options for selecting products based on varying downhole environments (corrosion, temperature, sour service considerations).
• Normative references: cross‑references to ISO 17078‑1 (side‑pocket mandrels), ISO 9000, ISO 15156 and industry codes/standards relevant to testing, calibration and materials.

Practical applications and users

Who uses ISO 17078-2:2007:

• Manufacturers and suppliers of subsurface flow-control devices (designers, QA/QC teams)
• Operators and purchasers in oil & gas production specifying downhole flow control requirements
• Testing laboratories and calibration facilities performing product functional and performance tests
• Engineering and procurement teams ensuring compatibility between side-pocket mandrels and flow-control devices

Typical uses:

• Specifying performance and test levels for devices installed in side-pocket mandrels
• Verifying supplier conformity through graded testing and documentation
• Selecting materials and manufacturing processes appropriate for specific well environments
• Ensuring repeatable calibration and functional testing for production acceptance
