Asset Management Process
Planning & Development
 The application of a technical, economical
and efficient asset management process
leads to optimal oil and gas final recovery
factors, added value thru the life cycle of the
asset and optimal ROI.
 The
asset
management
process
includes the key phases of screening,
evaluating, negotiating, initiating, appraising,
selecting, defining, executing, operating and
decommissioning.

Field/Reservoir/Completion
Surveillance & Optimization
 Surveillance & monitoring are keys to
understanding reservoir performance and
identifying opportunities that will improve
ultimate recovery.
 To be effective, Surveillance must be
exercised at both the static & dynamic levels
during the reservoir life cycle.
 Proper planning & modeling are instrumental
to successful Surveillance, enhanced
ultimate recovery and optimal ROI ($).

Mature Field Recompletion
Management
 Recompletions represent an attractive
opportunity for operators to increase
production, ultimate recovery and return of
the investment.
 Successful recompletions provide a great
opportunity to add
significant value to
mature assets.
 IWFS can help clients to select the best
recompletion candidates, estimate potentials,
prioritize opportunities and design suitable
operations to optimize asset value and ROI.

 Integrated nodal analysis models enable
operators to see the big picture to identify
production bottlenecks, increase productivity
and minimize technical and economic risk.

Well Flow and Artificial
Lift Management
IWFS SERVICES
 As reservoirs mature and reservoir potential
energy declines, continuous natural flow can
not be sustained.
 At this point, properly selected, designed and
managed artificial lift systems become a
powerful tool to enhance asset productivity
and recovery.
 IWFS can use updated methodology to
assist companies to select and manage
artificial lift technology for optimal field
productivity.

 IWFS holds an alliance with field operations
consulting firms of broad experience both at the
domestic and international level in the
supervision and execution of operations that
include: drilling and completion, workover &
recompletions, abandonment and artificial lift.
 Drilling operations include specialities on-shore
and off-shore among others: conventional
