Saturday morning, some 400 people protested against shale gas exploration and exploitation in the area and Chevron decide to halt activity in the region once again.

Hydraulic fracturing, or fracking, consists of pumping a water-sand mixture into underground rock layers to free the trapped oil or gas. Villagers are worried that the technique would affect the environment.

Chevron has permits to explore for shale gas in three localities in Vaslui county. In early October, the company received authorization to drill its first well in Silistea. Works, which were to start immediately, were delayed by protests twice.
