Permit Area

Fracción D sits on the eastern coast of the Santa Cruz region approximately 55 km north of Rio Gallegos.

The licence extends across an area of 280 km2 with oil production facilities already in place. Fracción D includes the existing Cañadón Salto field which is currently oil producing.


Petroleum Geology

Five gas prospects have been identified within the permit area lying at depths of around 1,300 metres below sea level. 



Local Infrastructure

Current production facilities in place facilitate the production and transportation of oil via tanker trucks.
The major San Martin pipeline which transports natural gas to Buenos Aires lies to the east, running through an adjacent block.



Upside Potential

Within Fracción D Echo has identified significant development, appraisal and exploration potential, both on the Cañadón Salto field and across the licence. The company initially estimates the block to hold up to 90.5 Bcfe Pmean, gross unrisked prospective resources, (62.4 Bcfe mid-case, 187.5 Bcfe high-case). Gaffney Cline & Associates.

Future plans for the block include an initial workover of 3 existing wells and the drilling, testing and completion of another well subject to results arising from the initial workovers. Satisfactory results from workovers will also lead to the acquisition of 230 km2 of 3D seismic.
