Sammendrag
Today rig/derrick and vessels is traditionally used to perform a P&A operation. With a rising
need for P&A operations combined with the wish of having a stable level of drilling
operations, a shortage of rigs will be a rising problem. Today’s operations are also time
consuming and costly for the operator, and fulfilling the regulations are often difficult.
Since plug and abandonment operations are a quite new operation faced on the NCS, the
development of tools/methods for this operation has been relative low. In order to handle
future challenges, new methods and tools needs to be developed. The operators have to take
the lead in this development, since the responsibilities of performing the operation lies with
them. The service companies needs to be encouraged to be innovative, and co operations
between companies will be needed. A higher focus on P&A should also be given at an earlier
stage, during the education of tomorrow’s personnel. New tools and methods can often be
hard to implement, since it usually means change in equipment and lack of experience with
the procedure. To be worth the risk, new tools should be developed in order to: * Save time
* Save money
* Provide better integrity.
This thesis will present the tools and methods used today, and also try to take a closer look at
new techniques on the marked and on future developments. Challenges today will be
discussed and the thesis will also try to take a look into the crystal ball to see what the future
will bring.
