In December 2007 the Interim Thesis has been appeared and a presentation has been given.
The Master project has been finished in July 2008 by the completion of the

Summary of the master project:
Producing oil and or gas is a very complex process. There are many
parameters to choose, such as where to place injector and producer
wells, the production rate etc.
At Shell, a simulator is used to approximate the amount of oil and gas
that can be produced from a oil or gas field. During the simulation
process, many parameters have to be chosen, such as minimum and
maximum pressure for respectively producer and injector wells and the
desired production/injection rates. To optimize the value of the field
with respect to these parameters, a solve backward in time is needed.
In this backward system, the adjoint of the original matrix occurs.
The aim of the project is to develop a robust solution method for the
problems of the adjoint system as they arise in the code MoReS.
