  • NS-1™ and NS-2™ Designed to supplement the API standards when conditions warrant it

NS-2™ Inspection Standard Technical Analysis when Compared With DS-1®  Inspection Standard

There are three main inspection standards for used equipment available within the Oil and Gas Industry. These are the American Petroleum Institute's RP7G-2, TH Hill Associates' DS-1®  and Fearnley Group's NS-2™.

Because of the increase in the number of 'complex' wells being drilled NS-2™ - which is designed specifically for use in this type of well - is being increasingly used.

However, there is a lack of knowledge as to the difference between NS-2™ and DS-1® . Therefore Fearnley Group have completed an analysis identifying where those differences are and why NS-2™ includes additional elements for 'complex' drilling projects.

So if you are involved in a drilling project that has any of the following drilling challenges and you would like to receive a copy of the comparison - then please complete the form below and send it to us.

Complex Wells where NS-2™ should be adopted: Offshore - Deepwater - ERD - HPHT - UBD - Managed Pressure - Slim and Super-slim.
