Annulus Pressure Relief System for Oil & Gas Well Stimulation up to 10,000 psi
M&W Engineering has developed an entirely new system for oil and gas wells, called the Annulus Pressure Relief System (APRS) based on easy to install and replaceable burst disc technology including all relevant certificates and Type Approval Documentation from DnV. All necessary parts come in robust wooden box and are all continuously re-certificed allowing for one-stop-shop operation. The APRS is certified to a working pressure of up to 10,000 psi (689 bar).
The APRS has been used by more than 10 oil and gas companies and service companies such as Shell, BP, Maersk Oil & Gas (now Total), Hess, Halliburton and Schlumberger for 1,000+ well stimulation jobs on – and offshore around the world. It has been widely used in the Danish and British parts of the North Sea, as well as other areas such as Iraq, Kazakhstan and the South China Sea.
