Use of AICDs to increase the Recovery Factor in fields with a strong bottom aquifer: Bretana Field - Peru Antonio Zegarra Willy García #FEXenergía
Slide 4: Regional Location
REGIONAL LOCATION #FEXenergía BRETAÑA FIELD • The Marañon basin is the southern extension of a larger basin that covers the Putumayo (Colombia) and Oriente (Ecuador) • Bretana Field is a subtle structure located on the south-eastern margin of the basin
Slide 5: Local Location
LOCAL LOCATION #FEXenergía • The field it is located at the southern end of the basin • Nearby fields to the Bretana asset have robust recovery factors with similar geologic characteristics Pipeline NAUTA Bretaña Field NATURAL RESERVE NATURAL RESERVE MATSES PACAYA SAMIRIA PETROTAL Block 95
Slide 6: Structure
STRUCTURE #FEXenergía BRETAÑA STRUCTURE • The trap is induced by a reverse basement fault that does not reach the Vivian formation and defines a subtle low relief, closed on all 4 sides of an elongated structure in the NW-SE direction
Slide 7: Electrical Profile
ELECTRICAL PROFILE #FEXenergía RESERVOIR ZONE: • GROSS = 144 m • NET RESERVOIR = 135 m • Phie (avg) = 23 % • Vclay (avg) = 7 % OWC (-2609) • K core (avg) = 1000 mD.

Slide 8: Structural Section
STRUCTURAL SECTION #FEXenergía 00 1 1 • North-South and East-West Sections of the Vivian Formation • Peaks in GR are not correlatable, consequently barriers to vertical flow are local. A very strong bottom aquifer is confirmed • High resistivity zones are found at different levels, indicating their

Slide 13: Geonavigation
GEONAVIGATION #FEXenergía IMAGE PERISCOPE EDGE (WELLS DRILLED IN 2021-2022) • Geonavigation has had to be used to maintain the trajectory of the well within the different channels • It has also served us to keep the trajectory as close to the top and avoid remnants of oil in the attic • It has been

Slide 15: Completion Design
COMPLETION DESIGN #FEXenergía • Efforts are made to keep high resistivity zones separate from low resistivity zones (high saturation – high permeability) • Isolate areas without any potential, due to the danger of producing sand
Slide 16: Completion Design
COMPLETION DESIGN #FEXenergía The implementation of the AICD technology consist in the Hanger PKR installation of a set of valves throughout the productive horizontal zone of the well.
