Title
(EN) CORRODIBLE DOWNHOLE ARTICLE
(FR) ARTICLE CORRODABLE EN PROFONDEUR DE FORAGE
Abstract
(EN)
This invention relates to a corrodible downhole article comprising an aluminium alloy, wherein the aluminium alloy comprises (a) 3-15 wt% Mg, (b) 0.01-5wt% In, (c) 0- 0.25 wt% Ga, and (d) at least 60 wt% Al. The invention also relates to a method of making a corrodible downhole article comprising an aluminium alloy, the method comprising the steps of:(a) melting aluminium, Mg, In,optionally Ga, and Ni, to form a molten aluminium alloy comprising 3-15 wt% Mg, 0.01-5wt% In, 0-0.25 wt% Ga, and at least 60wt% Al,(b) mixing the resulting molten aluminium alloy,(c) casting the aluminium alloy or producing an aluminium alloy powder, and(d) forming the aluminium alloy into a corrodible downhole article. In addition, the invention relates to a method of hydraulic fracturing comprising the use of the corrodible downhole article.
