Slide3Oil Fields in Ecuadorian Oriente Basin
Slide4Who are we?Petroamazonas EP, the Ecuadorian state-owned oil company, in charge of the operation of 65 oilfields, 63 of them are located in the Ecuadorian Oriente Basin (EOB), one in the Coast, and one in the Gulf of Guayaquil. The original oil in place (OOIP) for the fields of EOB
is
14.0 MMMBO
. Accumulated production until December 31, 2012 was
3.2
M
MMBO
, which represents a Recovery Factor (RF) of 22.9%. The final average RF estimated in primary recovery is about 34.4%.
Slide5Current statusThe majority of producing oilfields are in their mature stage, under primary recovery conditions
There are 4 main cretaceous
clastic
producing reservoirs. 3 of them behaves as volumetric with partial water influx drive, and one has an infinite acting aquifer

FIRST SCREENING OF IOR-EOR METHODS FOR THE PRODUCING RESERVOIRS IN THE SELECTED FIELDS
MODELING FOR RECOVERY FACTORS INCREMENTAL ESTIMATION DUE TO THE IMPLEMENTATION OF IOR-EOR STRATEGIES
GENERATION – UPDATING OF STATIC AND DYNAMIC MODELS OF THE SELECTED PRODUCING RESERVOIRS
IOR PROJECTS:
DRILLING OF NON CONVENTIONAL WELLS (HORIZONTALS, DEVIATED OF HIGH ANGLE, MULTI-LATERALS, DUAL COMPLETIONS…)
WATER FLOODING PROJECTS IN PROGRESS
Slide9Total OOIP estimated with deterministic methods of 14 billion bls, by using probabilistic methods, total OOIP (P50) could reach 18.3 MMMBO
. The difference between these two calculations (
4.3)
is considered an opportunity for growth, which has to be confirmed with detailed studies of the reservoirs and with additional data obtained during
oilfields
development

Slide14Modeling for Recovery Factor Incremental Estimation due to the Implementation of IOR-EORAll fields were stochastically modeled; Main Input: OOIP, Reserves, Structure, Well Types, Fluids Movement BehaviorThe fields with higher value were the fields with higher OOIPNew non-conventional wells and infill wells may increase the RF in 6%
Slide15IOR-EOR Growth Opportunity
Slide16Full field studies for ten Oilfields were conducted.
Three
of
them
have
detailed IOR
evaluations, one for CO2 injection and two
for Water Flooding.
In Summary, two types of development
are recommended:IOR: New wells and WF,
Recovery Factor may increase in at least 6%
EOR: Polymer and Surfactants, may increase
RF in an additional 4%
Generation – Updating of Static and Dynamic Models
