Multivariable Area Relevance FunctionMultivariable Area Relevance Function((Função de Importância Multiargumentos de Área - FIMAFunção de Importância Multiargumentos de Área - FIMA))
Ministério de Minas e Energia
Function Construction (FIMA)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 SelectionFIMA’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
AREA_1: area without any petroleum discoveries
1.Hydrocarbon direct evidence; 2.Relative prospectivity (*); 3.Lack of knowledge; and 4.Exploration activities
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 FIMA: Variables Standardization
The relevance of the basin area was classified from 1 to 9 according to the distance from the main information
Where: xy: size of the application area (pixel of 1 sq km) Ai (xy): standard value for the arguments in the xy position
Pi: relative weight for the argument, considering
For this work the weight was 17% for all arguments

•Hydrocarbon direct evidence- Relative distance to the closest well in the basin which has confirmed the existence of hydrocarbons
IPA: Hydrocarbon Direct Evidence
Ministério de Minas e Energia
•Relative prospectivity-Area of the effective basinwith possibility to have anyfield discoveries
IPA: Relative Prospectivity
Ministério de Minas e Energia
IPA: Lack of Knowledge
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

IPA: Lack of Knowledge

• Exploration activities- Relative distance to theclosest exploration block polygon in the basin
IPA: Exploration Activities

• Production activities- Relative distance to theclosest O&G field polygon in thebasin

•Downstream infrastruture- Distance to the center of the closestdownstream facility. For places outside the sedimentary area the range of 5 kmwas attributed for existent facilities and20 km to the planned ones

ConclusionsConclusions
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
Ministério de Minas e Energia
ConclusionsConclusions
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
Ministério de Minas e Energia
ConclusionsConclusions
Maps updating The dynamics of the O&G sector turns the updating
of the database mandatory, in order to keep the maps reliable
