EXPANDABLE SCREENS TECHNOLOGY

• Effective sand control
• Formation support (eliminate/reduce annulus)
• Larger ID for easier well intervention access

• Expandable screens provide
• Effective sand control
• Formation support (eliminate/reduce annulus)
• Larger ID for easier well intervention access
• Enables accurate production logging

SCENARIOS HYPOTHESIS
8
Case A Expandable Technologies in dual zone
application

• Insufficient gravel quantity
• Abandonment of main well and side-tracking
• Expandable Technologies as alternative to Gravel
  Pack

9
Case A Economic Evaluations
10
Case B Expandable Screen in horizontal well

• Horizontal well with OHGP
• Bad event swelling shales
• Side-tracking with expandable screen

11
Case B Economic Evaluations
12
Case C Solid Casing Expansion

• Need for insulating the upper interval
  (cladding)
• No production increase

• Need for insulating the upper interval
  (cladding)
• No production increase
• Unique differential Cash flow is cost saving of
  850,000

Adoption of Expandable Technologies at 10 years

Synthesys within Eni group

Synthesys within Eni group
This conclusion might be conservative. A major
EP company announced a double value creation
(320 M) with almost the same number of
installations
16
Conclusions

• Main features of Expandable Technologies
• Increase in production due to larger ID downhole
• Cost savings in comparison with alternative
  solutions
• Though, need to confirm technologys longevity
• Anyway, Expandables are already considered a
  breakthrough technology
• The most ambitious application in drilling is
  the development of the monodiameter well-bore

• Increase in production due to larger ID downhole
• Cost savings in comparison with alternative
  solutions
• Though, need to confirm technologys longevity
• Anyway, Expandables are already considered a
  breakthrough technology
