Well intervention stack safety and equipment selection for offshore/onshore operations

摘要

The following article introduces the Zeta Safety System developed by CTES with support from BE The new system,comprising two primary components,the Zeta Model and the Zeta Gauge,allows the operator to design safer well intervention stacks and monitor stresses on the stack during intervention operations.Following an introduction and background,the article describes:1) failure modes;2) the Zeta Model and Zeta Gauge;3) a user's perspective;4) field results of several applications;and 5) project status and future plans.
