Prospectivity

All technical data is freely available online (https://bndh.gob.do/en/), from the National Hydrocarbon Database (BNDH).  The National Database of Hydrocarbons is a compendium and digital file -in the standard format of the oil industry- of all the geological, geophysical and seismic information collected through exploration and prospection activities of hydrocarbons in Dominican soil and sea since 1904. 

This includes:

• 21,500 km of 2D seismic, representing a value of approximately US $ 100 million

• 1,491 maps, 805 seismic profiles, 212 well records, 321 records / reports, 209 magnetic tapes containing seismic lines in different regions of the country

Basins on offer

Cibao Basin

Map and overview

Located in the north of the country with 6 onshore available blocks

Cibao Basin Stratigraphic Column

 Geological Map and Petroleum system

• Source
  Rock: Tabera Group is a hypothetical source rock,
  which is in the oil window since late Oligocene. Based in TOC interpretation
  from Logs (San Francisco-1 well) shows potential Source rocks in Guarabo fm.
• Reservoir
  Rock: San Francisco–1 well and outcrops has shown
  good reservoirs along the Miocene and Pliocene.
• Seal
  Rock: Several siltstone & clay from Oligocene
  & Pliocene.
• Trap:
  Seismic shows a highly deformed basin with high angle transpressive faults,
  positive flower structures and anticlines – All potential HC traps
• Timing:
  Potential deeper source rock (Tabera Group) would have reached maximum peak of
  generation during Miocene

Highlights

Enriquillo Basin

Map and overview

Located in the west of the country with 3 onshore available blocks

Cibao Basin Stratigraphic Column

Geological Map and Petroleum system

• Source
  Rock: Three source rocks were defined – Trinchera Fm
  in early oil window towards the central part of the basin; Sombrerito Fm in the
  early to middle oil window; Plaisance Fm in late oil window and early gas
  window
• Reservoir
  Rock: 
  Outcrops and wells have showed several Eocene, Oligocene (?) and Miocene
  reservoirs levels in basin
• Seal
  Rock: Several shales levels from Eocene to Pliocene
• Trap:
  Highly deformed basin with high angle transpressive faults, thrust and salt
  related structures, and fracture limestone.

Highlights

Azua Basin

Map and overview

Located in the southwest of the country with 1 onshore available block

Cibao Basin Stratigraphic Column

Geological Map and Petroleum system

• Source
  Rock: Shales from Neiba & Trinchera Fm,
  Hypothetical SR from Jura Fm.
• Reservoir
  Rock: Conglomerate facies from Ocoa Fm, sandstones
  from Trinchera/Arroyo Blanco Fm
• Seal
  Rock: Marls from Sombrerito Fm & shales from
  Arroyo Blanco Fm.
• Trap:
  Seismic shows a highly deformed basin with high angle transpressive faults,
  positive flower structures and anticlines – All potential  HC traps
• Timing:
  Potential deeper source rock (Jura Fm.) would be maximum peak of generation
