Three Well Control Methods Comparison Including Application & Practices Work over rigs; Jake S-9 Block (6)

Abstract

Well control problems plagued the petroleum industry since it's infancy and known as losses of valuable resources, costs increasing, environmental damages, personnel casualties. The objective of this research is to analyzes well control case study for work over rig; block-6. Three different killing methods have been applied: Driller; W&W and concurrent methods. The formation, borehole; wellhead; rig equipment and lay out are considered as a communicating system, in which the three are influenced and restrained by each other. Concurrent method has been applied to kill the well. It is a complex technique combining both driller and W& W methods; which it is not common in the oil industry and is the first time to be applied in the Sudan for work over rig.
