from the reservoir management team of the operator and combined
efforts with offshore production team to actually move the ICVs. This
process is often poorly understood and implemented. Frequently,
because of a lack of knowledge or lack of trust in the technology, ICV
movements are neglected, diminishing the potential benefits of the
technology. An important movement within the industry is toward
digital oilfields, which integrate all of the data coming from the well
into real-time monitoring systems coupled with predictive models that
assist the decision-making process of the parties involved in the produc-
tion life of the well. The ultimate level of the system would be a fully
automated decision-making system; however, this will take a significant
amount of time to develop due to the enormous gap in current downhole
monitoring technology and the uncertainties associated with current
modeling software and intrinsic reservoir and geology uncertainties.
Intelligent completions have been proven to be a crucial reservoir
management tool with the potential to increase the ultimate value of
an asset by means of intervention avoidance and increased recovery
factors. It is also evident that its application has gained traction recently,
as operators are seeking more efficient ways to complete wells and
use the completion as an active well performance optimization tool.
However, these benefits are only going to materialize if the system
is effectively and actively used. To improve usage, more knowledge
transfer to the final user is necessar y to foster confidence to manipulate
the valves freely, reliably, and actively control the fluid outflow up to
the surface. The reasons behind the fear of moving an open ICV are
understandable and ways to increase confidence in the technology
are under way. With a better understanding of the application, scale
formation, erosion, and other potential failure modes and prevention
measures, operators can gain confidence in actively manipulating
ICVs and optimizing the performance of the field.
Additionally, a real-time decision support system must be imple-
mented to facilitate the decision-making process of the user; this
can occur through the establishment of a comprehensive workflow
associated with predictive modeling and improved sensing capabilities
that will allow for improved predictive accuracy of the results of an
ICV movement to the overall field strategy. The decision to implement
intelligent completions in a field development plan can become an
important risk mitigation tool. However, the consideration to install
it and all the decisions that come with effective implementation have
the most impact when performed early. This article aims to provide
enough data to give confidence regarding several perceived risks
associated with technology selection, planning, deployment, and use.
A more comprehensive analysis should be performed to confirm
the value of its application; but, often, intelligent completions have
been kept out of conceptual phases because of the high perceived
risk associated with past experiences or inaccurate data, or when the
benefits of its use are not fully understood or realized.
Intelligent completions have a role in keeping deepwater and ultra-
deepwater developments more profitable and competitive. However, a
mindset of diminishing the importance of the completion as the most
relevant phase of the well construction process has posed the greatest
threat for broader adoption within the industry. •
