“Peru is currently a net oil importer and a natural gas exporter, but rising exploration and development may lead to increased production and exports of both oil and gas in the next few years.” Quoted from the Energy Information Administration country analysis brief.
“The chances of rogue fractures due to shale gas fracking operations extending beyond 0.6 kilometres from the injection source is a fraction of one percent, according to new research led by Durham University.
