Non-destructive Testing of Hydraulic Fracturing Components

Flow iron is used in hydraulic fracturing and flowback operations. This process is also referred to fracking. Flow iron requires periodic non-destructive testing to assure fitness-for-service. Non-destructive testing methods include ultrasonic thickness testing, phase,d array, testing, radiographic testing, magnetic particle testing and visual testing.

flowback, and ,testing, activities are minimised. For example: • Venting of gas to the atmosphere is to be avoided and when this is not possible for operational or safety reasons it should be kept to a minimum. • During ,flowback, of hydraulic ,fracturing, fluids and extended well ,testing, periods, gas will

As the ,fracturing, process proceeds, viscosity-reducing agents such as oxidizers and enzyme breakers are sometimes added to the ,fracturing fluid, to deactivate the gelling agents and encourage ,flowback,. Such oxidizers react with and break down the gel, reducing the ,fluid,'s viscosity and ensuring that no proppant is pulled from the formation.

Hydraulic fracturing consists of using a fracturing fluid pumped under pressure in the range of, 700–1200 bar, for gas or/and oil-bearing formations. The amount of water needed for fracturing is usually between 10–25 thousand cubic meters and depends on the length of the horizontal part of the borehole.
