Margarita field lays between Chuquisaca and Tarija

The issue between Tarija and Chuquisaca, over where the natural gas fields of Margarita belong to, has now more information, as Pagina Siete reports today:

Regarding the dispute between the departments of Tarija and Chuquisaca, the Government confirmed that the Margarita and Huacaya fields share the Huamampampa reservoir 1b (H1b), located in the Caipipendi area and that studies should be made to determine the factor of distribution for both regions.

“Margarita and Huacaya have a shared reservoir, Huamampampa 1B, according to the data achieved so far by Repsol, the operator of the block Caipipendi”, said yesterday the Minister of Hydrocarbons, José Luis Gutiérrez, in the oral report presented at the request of the Plural economy, production and industry Commission, Lower Chamber of the National Assembly [former Congress].

However, Tarija and Chuquisaca civic committees expressed different positions with respect to this claim.

Members of Tarija civic committee rated the Gutiérrez explanation as biased in favour of Chuquisaca, because they argue that until there is absence of a study to determine that the reservation is shared, the executive body cannot claim it.

In the meantime, Chuquisaca civics claimed that the hiring of a reputed international company should be speed up  to fix the distribution of the reserve between the departments in conflict.

Gutiérrez, drew the composition of the H1b reservoir before the civics (see above chart). He indicated that the connectivity that exists through between Margarita and Huacaya fields was discovered when Repsol drilled shaft Huacaya X 1 (HCY – X 1), and through various tests of pressure, a reaction was observed from that connection , between Wells Margarita X 3 and X 4 (MGR – X 3 and MGR – X 4).
