Abstract: The present invention offers some general specifications for the design, assembly, and adaptation of a rotating cylinder electrochemical cell into an autoclave, of a high temperature and pressure system for corrosion studies that simulate operating conditions in pipelines, as well as the operation and safety of an autoclave to evaluate the electrochemical process of metal surfaces exposed to aggressive aqueous solutions. The electrochemical cell consists of an array of three electrodes that include a rotating cylinder electrode designed to operate hermetically, a reference electrode and an auxiliary electrode. The rotating cylinder electrode is considered to be the working electrode, where the oxidation and electrochemical reduction processes are studied. However, the use of the method described in this work can be extended to other testing environments and materials by taking into account the physical and chemical properties of the fluids and materials to be used in order to avoid any risk for the operator.

Abstract: The device is based on the principle of downhole shut-in of oil producing wells that do not flow to surface self-powered but require the injection of gas to lighten the fluid column and thus enable the well to produce. This downhole shut-in device comprises a check valve, an anchoring system, a seal system; an untethering system, a shock absorber and a sleeve for the protection of pressure and temperature memory probes. The objective of the downhole shut-in device is to obtain characteristic information of the fluid-rock system from variations in the pressures recorded in order to obtain the dynamic characterization of the reservoir.

Abstract: Detector of Slickline Irregularities (DILA) is a electronic system to detect and assess irregularities in production wells or to a new slickline by measuring eddy currents or eddies or Foucault currents. The system lines can vary in diameter depending on the operation to be performed on each well. The electronic system includes an optical encoder, eddy current sensor, eddy current reader, an electronic module for data acquisition and a computer. The detector monitors the integrity of the slickline in the well, interprets and records the data for graphing and reduces failures in the slickline as a result of rupture caused by excessive stress or collisions within the producing wells, detects flattening and bending, lack of nickel coating, porosity and corrosion.
