The Effect of Proper Selection of Drilling Fluid on Drilling Operation in Janbour Field

Akram Hamoodi, Ararat A. Rahimy, Amanj W. Khalid


Selecting a proper drilling fluid has always been a difficult task to overcome by drilling mud engineers. There are some constraints such as formation lithology encountered, the range of temperature and pressure of the formation, environmental considerations and cost that play a paramount role in the selection of the proper drilling fluid. In this paper, well data from Janbour Oilfield was used and analyzed. The concentration lies on the second section of the well since it shows to be the most problematic one.  Salt saturated mud was designed in lab and compared with the mud used to drill the second section of the well. The final result of this paper indicates that the designed salt saturated mud is superior to the mud used to drill the section.
