Optimum trajectory in terms of good well placement, drillability and collision risk avoidance was a priority in planning these wells in a tight network of over 350...

... horizontal stresses to decrease, whereas shear failure gradient (minimum mud weight requirement to prevent borehole collapse or breakouts) may still remain higher depending on stress magnitudes, strength of sandstone reservoir, intra-reservoir shale and wellbore trajectory. Thus, drilling a very high angle...

... the well trajectory. The well was drilled 20m down in TVD as a pilot well to perform down hole fluid profiling using the Modular Formation Dynamics Tester (MDT), however, MDT could not be carried out due to heavy mud losses and the well was plugged. Finally, it was decided to sidetrack the well. MDT...
