Abstract
Summary
In this case study, a Maximum Reservoir Contact (MRC) had multiple objectives to achieve in a 3ft thick limestone layer.
First it needed to detect the high risk water zones.
Second, the areas with high Gas Oil Ratio (GOR) needed to be identified and avoided
Third, that thin layer needed to fall within a certain permeability range.
Fourth, the geology is uncertain with fast changing dip and faults.
Several technologies were combined including a first in the UAE, the ElectroMagnetic (EM) images in Oil Based
Mud OBM, to resolve for all these challenges and deliver a successful 13000ft long horizontal.
