Onshore drilling in Espírito San-
to began with the drilling of two
wells in the city of Conceição da
Barra, in 1959. In total, 1,769 wells
have been drilled more frequent-
ly in the 1980s, when the average
drilling was 76 wells per year, and
also in the 2000s when the aver-
age drilling was 44 wells per year.
Between 2016 and 2018, the an-
nual average of onshore drilling
was reduced to 3 wells, marking it
the lowest activity level since the
1970s. However, 2019 and 2020
indicated a possible return of on-
shore drilling activity in Espírito
Santo (chart 1). Between the two
years, 61 wells were drilled by oil
companies Petrobras, BGM, and
Imetame. Petrobras resumed
onshore drilling in the Fazenda
Alegre and Cancã fields, while
BGM focused its efforts on the
Suindara field and Imetame on
the Rio Ipiranga field².

2.2. Declarations of hydrocarbon traces
Since 1998, when the declaration
of hydrocarbons traces became
mandatory, 221 declarations from
the offshore origin and 222 decla-
rations relative to onshore drilling
were issued in Espírito Santo. The
first declaration relative to offshore
drilling was issued in connection
with the BES-100 block (which cov-
ers the Golfinho and Canapu fields)
and from the Peroá field, both bor-
dering the municipalities of Aracruz
and Linhares.
Between 2018 and 2020, zero off-
shore hydrocarbon declarations of
hydrocarbon traces were issued in
Espírito Santo due to the reduction
in exploration activity in the State
(chart 2). During this period, Brazil
issued 24 offshore declarations of
hydrocarbon traces, all concentrat-
ed in the Campos, Santos, and Ser-
gipe basins. In 2021, the most re-
cent period, Petrobras announced
the existence of natural gas in
block ES-M-669. This block is part
of Petrobras and Equinor's cam-
paign to reach the pre-salt layer in
the Espírito Santo basin³.
Onshore, the first declarations of hy-
drocarbon traces were issued in the
Mosquito and Fazenda Alegre fields,
located in the municipalities of São
Mateus and Jaguaré. The highest
frequency of issuance occurred
between 2005 and 2013 when the
annual average issuance was 17
declarations per year. The main oil
companies that conducted this pro-
cess were Petrobras and Vipetro.
Between 2016 and 2018, no onshore
declarations of hydrocarbon traces
were issued in Espírito Santo due to
the reduction of exploration activity
in the state (chart 9). In this period,
Brazil issued 41 onshore declara-
tions of hydrocarbon traces, all con-
centrated in the basins of Potiguar,
Recôncavo5, and Parnaíba.
Between 2019 and 2020, 4 dec-
larations of hydrocarbon traces
were issued on the Espírito Santo
for onshore drilling. Imetame an-
nounced the discovery of oil and
natural gas in block ES-T-487 and
BGM
announced the discovery
of oil in three wells in the Suinda-
ra field. In 2021, the most recent
period, Imetame announced the
existence of Oil in block ES-T-441,
located in the municipality of Jag-
uaré. This block was acquired in the
14th round of the ANP auction held
in 2017.

2. Of the total 61 wells drilled onshore between
2019 and 2020, 30 are currently producing,
which represents a 49.2% success rate
3. The project, entitled "Prospector de Monai"
will be essential for them to be able to assess the
exploration of other concessions acquired in the
11th round of the ANP auction, which, so far, has
not presented areas of interest for exploration.
