Estimated mud weight window for well bore stability case study aldinder field well tawakul-1

Abstract

The Well bore instability is one of the main problems that engineers meet during drilling. The case study in this research estimated the formation pore pressure and fraction pressure using Eton and ratio mothed. The results show that the stability of wellbore is quite a challenge because of low pore pressure compare to the fracture pressure with an existing of the shallow gas beds. These findings concluded the section of the Blue Nile Basin has to be well cemented and close, although, the drilling fluid has to be at minimum as much of its pressure and density with slow operation speed and prepare to fluid washing process
