摘要

Oriented perforation has been used to prevent sand production on many of StatoilHydro's fields on the Norwegian Continental Shelf(NCS)during the last decade.As an alternative to mechanical sand control measures,the operator has chosen oriented perforating in several platform and subsea developments,mature fields and HPHT reservoirs.Before 2000 the tool design for passive orientation was generally inadequate,and misalignment of perforations was common.However,collaboration between operators and service companies has led to significant improvements in orientation systems.Several suppliers now offer orientated Tubing-Conveyed Perforation(TCP)systems that are qualified for use by StatoilHydro.Some of these include devices for accurately measuring orientation while perforating.
