Qualification and Use of a Self-Equalizing Subsurface Safety Valve in Large-Bore, High-Rate Gas Well Applications

The concept of using natural gas as an energy source has increased to such an extent that there has been a notable worldwide<br>increase in its usage. Supplying this growing demand has been an industry challenge. To this end, many operators have<br>implemented the use of large-bore, high-rate gas wells for effective development of gas fields. One of the key components in<br>this type of completion is the subsurface safety valve (SSSV) because of its primary role of containing the hydrocarbon in the<br>event a well loss should occur. The SSSV is critical to the protection of the lives, assets, as well as the environment in the<br>surrounding vicinity.
