A method of oil recovery by applying an electrical signal to a reservoir of interest, wherein said method comprises the following steps: obtaining the characteristic frequency of the water-oil interface of the reservoir; and applying the electrical signal to the reservoir, wherein said electrical signal is an alternating current signal or a combination of a direct current signal and an alternating current signal, and wherein the frequency of the alternating current signal is the characteristic frequency of the water-oil interface, thereby producing alteration of the water-oil interface and movement of the oil for extraction.

A dissolvable alloy, the chemical composition of which comprises aluminum between 2.5% and 9%; zinc between 0.1% and 1.5%; iron between 0.01% and 3%; and magnesium the remainder, such alloy being usable in tools and components of the petroleum industry.

Dissolvable magnesium alloy

A device and method for testing a rock specimen in order to determine the fracture toughness (K) thereof. The device comprises: a frame; a hydraulic pressure testing rig supported by the frame and comprising a pressure gauge, a lever and a pressure diaphragm; a storage tank for storing hydraulic fluid and supported by the frame; and a pressure chamber supported by the frame, in which the test specimen is placed to be subjected to hydrostatic pressure through conduits that connect said pressure chamber with the storage tank in fluid communication.

An anode slurry for cathodic protection to underground metallic structures, preferably for casings of hydrocarbon producing wells or water injecting/producing wells, comprising a granulated electrical conducting material as anode and optionally a granulated filler with high electrical conductivity (backfill). There is also disclosed a method for providing cathodic protection to underground metallic structures by injecting an anode slurry into the underground formation containing the metallic structures.
