Challenge: The operator requested a fluid
system capable of delivering maximum performance for its HTHP well. To ensure
accurate XPT pressure points, the operator put special focus on filter cake
thickness and quality. Also, it was imperative that the system deliver minimal
formation damage
Solution: Based on previous M-I SWACO
experience in the North-Sea, a paraffin-based PARATHERM HTHP low viscosity
system was selected to drill the well. It was decided that the characteristics
of the PARATHERM system, including the low viscosity profile, excellent hole
cleaning capability to achieve optimum equivalent circulating density (ECD),
and high resistance to contaminants would contribute to the success of this
challenging HTHP well
Results: The well was drilled successfully and all XPT pressure points were
achieved, thus meeting the operator’s objectives
