Formulation for abandoning oil wells and process for producing said formulation

Abstract

Formulation applied to the abandonment of oil wells, and its production process, said process comprising steps specifically developed for the effective obtention of the product. The formulation can be used in environmentally sensitive areas near oil production wells, exhibits a long service life and improved thermal resistance. Consequently, there are eliminated concerns related to the particle deposition and the consequent entrapment of mechanical elements in oil wells subjected to abandonment operations. In addition to being reflections of the composition itself, the properties of the aforementioned formulation are also directly related to the way in which the production process is carried out, especially in terms of the order of addition of raw materials and also in relation to process parameters, such as agitation, resting periods, times involved in each of the steps and other correlated aspects.
