ENMC – COMPETENCIES/ATTRIBUTIONS
ENMC - Global
Since 2013, ENMC (National Authority for Fuel Market) has became the central stockholding entity
responsible for the constitution and maintenance of the strategic emergency stocks of oil and petroleum
products.
Additionally, ENMC assumed new responsibilities, such as:
1
Monitoring the fuels market, including crude oil, petroleum products and piped liquefied petroleum gas;
2
Promoting the technical safety and fuel quality;
3
4
Promoting biofuels and other renewable fuels, participating in the definition of new policies, in order to
ensure consumer protection;
Monitoring the prospection, research, development and exploitation of oil resources, as will be
explained hereafter.
ENMC – COMPETENCIES/ATTRIBUTIONS
ENMC – Petroleum Exploration and Production
ENMC is responsible for technical matters regarding petroleum exploration and production:
1
Automated management, treatment and development of technical data and information resulting from
petroleum exploration and production activities
2
Promote the knowledge of areas with petroleum potential near the companies
3
Negotiate and ensure the procedures for granting petroleum exploration and production rights
4
Evaluate and approve work programs and technical projects and supervise activities during the
contracts execution, ensuring that the legal dispositions and rules are followed
Propose or collaborate in the elaboration of rules, technical specifications and regulations relative to
5
petroleum exploration and production and follow the transposition of Directives in which DGEG is the
sectorial competent authority

MAIN POTENTIAL EXPLORATION AREAS IN RECENT YEARS
OFFSHORE
More than half of the Portuguese EEZ has potential
for exploration:
•
Sediment thickness
•
Multiple trapping structures
•
Mesozoic to recent age sediments

MAIN POTENTIAL EXPLORATION AREAS IN RECENT YEARS
ONSHORE - Pre-Salt Plays, present in all Mesozoic basins, with reservoir quality variable and expect to
contain mainly gas.
MAIN POTENTIAL EXPLORATION AREAS IN RECENT YEARS
Silves Fm conglomerates at the
Serra de S. Luis, near Coimbra.
Silves Fm sandstones at Bulgens, Algarve.
MAIN POTENTIAL EXPLORATION AREAS IN RECENT YEARS
•
ONSHORE - Lower Jurassic Organic shales, with geographical distribution in the Lusitanian Basin. These shales
form the lower part of the Brenha fm and according to studies, can reach a Net thickness over 150 m (in some
areas) and values of TOC fair to rich (from 5% to 8% or more). These can be potentially shale oil/gas reservoirs.

Lusitanian basin the most explored.
Final Notes (2/2)
•
•
•
•
Basins are underexplored;
Increasing interest in petroleum
exploration in Portugal, with more 3D
geophysical acquisitions and
exploration wells;
Attractive granting rights and fiscal
system;
Market proximity
With the existent
activities and the
ones foreseen, the
probability of an
economic discovery
increases …
