The disclosed method proposes, for the mixing of a solid and dry granular mixture and a liquid bituminous binder, the solid and dry granular mixture being a mixture of two fractions of constituents, one of which is a coarse fraction including aggregates, the other fraction a fraction of submillimetre fines, that the mixing includes at least two consecutive mixing steps: an aggregate-preimpregnation step, consisting of mixing the coarse fraction of the granular mixture with a part of the bituminous binder, in a quantity at least sufficient for coating the aggregates and at least partially filling the open pore spaces of the aggregates; and a covering mixing step, which consists of mixing the preimpregnated coarse fraction of bituminous binder and originating from the first mixing step, with the balance of the bituminous binder, required for the manufacture of the electrodes, and with the fraction of fines of the granular mixture.

Remediation of a hydrocarbon producing well bore in a subterranean formation includes injecting fluid containing self-degrading particulates into the well bore in order to stop production of hydrocarbon from the well bore prior to commencement of remedial operations and to temporarily seal the well bore from fluid transmission between the well bore and the formation prior to commencement of the remedial operations, and commencing the remedial operations upon the well bore. Examples of the remedial operations include injecting weighted fluid into the well bore, inserting a down-hole tool into the well bore, casing treatment, annulus treatment, well bore wall treatment, cementing, and refracturing. For refracturing, the fluid containing the self-degrading particulates can be injected until a down-hole pressure exceeds a fracture breakdown pressure of new fractures that will be produced by a perforating tool lowered into the well bore.
