Introduction

Several operator companies are migrating their project development approach from flow
assurance issues prevention to issue risk probability management. This approach allows
to defer cost for the facility development while possibly increasing the operating cost and
difficulty.

Project cost optimization CapEx vs OpEx

Projects tend to be CapEx-lean and OpEx heavy due to the uncertainty in reservoir perfor-
mance. If reservoir is a strong producer and the produced commodity market is expected to
be strong, then additional facilities may be developed.

Historic frequency of blockages based on remediation

The risk-based approach to flow assurance relies on historic frequency of blockages to
forecast the future probability of a blockage.
Historic blockage frequencies and trends were presented in Chapter 5.
