Effective basins
 Effective Basin Area (sq km): Sedimentary basin subset with
real chances for petroleum or natural gas accumulations.
Can also be defined as the geographical union of their
effective plays
 Absolute Prospectivity (sq km): Prospective area with a
regional geologic risk, representing the total area of the
prospects weighted by the related subplay chances

Multivariable Area Relevance Function
(Função de Importância Multiargumentos de Área - FIMA)
Ministério de
Minas e Energia

Function Construction (FIMA)
General concept:
 It is a function to be applied over each studied element area
in order to define its relevance (IPA) for the petroleum and
natural gas sector

IPA = FIMA (AREA)
Ministério de
Minas e Energia

FIMA’s Variable Selection
Six variables were chosen based on E&P information,
which were applied over the three types of areas
defined for the work with their degree of relevance for
the oil and natural gas sector
Hydrocarbon direct evidence;
2. Relative prospectivity (*);
3. Lack of knowledge; and
4. Exploration activities
1.
AREA_1: area without any
petroleum discoveries
AREA_2: area with petroleum
discoveries
5.
Production activities
AREA_3: area with
downstream infrastructure
6.
Downstream infrastructure
(*) Higher prospectivity for higher values, classified from 1 to 9
Ministério de
Minas e Energia

FIMA: Variables Standardization
The relevance of the basin area was classified from 1 to
9 according to the distance from the main information

Lack of knowledge
 Match between the chance degree and the exploratory stage
of each play (from 1 to 9 according to the degree of
knowledge)
 The result means the uncertainty of the behavior for the
regional geological factors related to the O&G
accumulations
 The higher values for this argument shows the least studied
areas in the basins.
 Areas out of the effective basin got the value 1

Conclusions
In this project a georeferenced database was built,
with hundreds of mappable attributes, of which some
are original, related to the oil and gas sector relevance
of any area in the country
The results are unpublished and specially important
for the Ministry of Mines and Energy
 It can be improved in other projects with additional
information and interpretation
 It can be used to support Exploration and Production
policies related to the National Energy Plan

Conclusions
The final map (IPA) from this project allows evaluating
the relevance of places greater than 1 sq km for the
O&G sector up to the range of 200 miles from the
shore line
The final map of IPA also shows that most of the
country area has some relevance for the O&G sector.
Exceptions are some basement areas without
infrastructure and sedimentary basins with no
potential for oil and gas
The basins with higher degree of E&P activities, like
most of the offshore basins, are pointed in the maps
with higher relevance, as expected

Conclusions
Maps updating
 The dynamics of the O&G sector turns the updating
of the database mandatory, in order to keep the
maps reliable
