Integrated Asset Management and Optimization Workflows 199

Fig. 6.1 Holistic concept of integrated asset management (IAM).

simulation model represents a starting point and one of the input modules for
an IAMod. A reservoir model integrates the reservoir geological model, rock
and fluid properties, fluid flow model with recovery mechanisms, drilling
and well completions, and the production history. The concept of IAMod
introduces multiple model realizations as a result of uncertainty quantifica-
tion and modeling, integration with process and surface facilities, and pipe-
line networks and economic exploitation models.
With integration of information and data management, strategic plan-
ning with risk and opportunity assessment and decision analysis—all in
the frameworks of stochastic scenario management and optimization—
IAM concepts are being used more often. They are now becoming a stan-
dard way of modeling entire oil and gas facilities with a view to optimizing
existing facilities or developing new ones, as well as applying them to daily
development, operations, and maintenance decisions.

6.2 OPTIMIZATION APPROACHES

In 2011, New Technology Magazine (Cope, 2011), David Millar, senior
vice-president, reservoir optimization, SPT Group stated, “Currently opti-
mization is applied to perhaps 10% of oil and gas modeling scenarios.
I foresee that within a decade the majority of modeling cases will use
optimization.” With the aggressive expansion of IAM projects and DOF ini-
tiatives, process optimization techniques are rapidly gaining ground in the
oil and gas industry. Over the past several years, many new software tools
