Work Package one: Well flow modelling

Key team members :

Team lead:  Ricardo Vasques, VP of Engineering at Welltec A/S.

A PhD student will be recruited to DTU Mechanical Engineering and supervised by Professor Jens H. Walther, DTU MEK. Also, a Post Doc will be recruited to DTU Chemistry to work on fluids and EOR. The work in this WP will be performed in close collaboration between Welltec, LRC (simulation) and DTU (Mechanical Engineering and Chemistry).

Overview:

Topics covered by WP1 include scale formation modelling and modelling of particles in wells, derived from the reservoir through rock failure or from the drilling process. These particles can influence the efficiency of well tool performance and lead to erosion detrimental to the well control objectives and modelling of particles in the well in various phase applications has not yet been achieved. 

This task will be part of WP1, with particular attention from Welltec to the impact of solids plugging and the erosion of well control devices. When flow from the well is initiated, most oil and gas wells have an introduced fluid (a fluid not native to the reservoir such as a drilling or completion fluid) in the wellbore. The removal or unloading of that fluid can have an impact on the short and long term well performance and current attempts to model the process of well start up and fluid unloading have not been rigorous. Development of CFD models to fully represent all of the transient fluid dynamics and well geometry of this process are required in order to fully describe the well performance.
