20120080189 | DEGRADABLE COMPOSITIONS, APPARATUS COMPRISING SAME, AND METHODS OF USE - Compositions, apparatus incorporating a composition, and methods of use are described, one composition embodiment consisting essentially of one or more reactive metals in major proportion, and one or more alloying elements in minor proportion, with the provisos that the composition is high-strength, controllably reactive, and degradable under defined conditions. Compositions of the invention may exist in a variety of morphologies, including a reactive metal or degradable alloy processed into an alloy of crystalline, amorphous or mixed structure that may constitute the matrix of other composition, for instance a composite. Methods of using apparatus comprising a composition, particularly in oilfield operations are also described (e.g. flow and displacement control, sensors, actuators). This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims. | 04-05-2012 |
20130087061 | DISSOLVABLE MATERIAL APPLICATION IN PERFORATING - A shaped charge includes a charge case; a liner; an explosive retained between the charge case and the liner; and a primer core disposed in a hole in the charge case and in contact with the explosive, wherein at least one of the case, the liner, the primer core, and the explosive comprising a material soluble in a selected fluid. A perforation system includes a perforation gun, comprising a gun housing that includes a safety valve or a firing valve, wherein the safety valve or the firing valve comprises a material soluble in a selected fluid. | 04-11-2013 |
20130133897 | MATERIALS WITH ENVIRONMENTAL DEGRADABILITY, METHODS OF USE AND MAKING - A valve device for restricting flow is provided that includes a degradable portion. A method of temporarily blocking flow is also provided which includes a degradable portion of an oilfield element. | 05-30-2013 |
20130327545 | SYSTEM AND METHOD UTILIZING FRANGIBLE COMPONENTS - A technique facilitates use of frangible components. The frangible components may comprise components of a gripping tool, e.g. anchor, used in a variety of applications, including well related applications. The tool is provided with a plurality of gripping members which each comprise a frangible structure. The gripping members may be selectively deployed to provide the desired gripping within a tubular structure, e.g. an open wellbore or well casing. The frangible structure in each gripping member is designed to break down into smaller portions after being exposed to a predetermined input, thus facilitating removal of the tool from the tubular structure. | 12-12-2013 |
20130342211 | Impedance Spectroscopy Measurement Device And Methods For Analysis Of Live Reservoir Fluids And Assessment Of In-Situ Corrosion Of Multiple Alloys - A method for analyzing fluid withdrawn from a subsurface formation includes disposing the withdrawn fluid in a chamber and maintaining the fluid in the chamber substantially at a same temperature and pressure as exists in the subsurface formation. Electric current is passed through the fluid in the chamber using at least one electrode made from a selected metal, the electric current comprising direct current and alternating current of frequency sufficient to determine at least one of (i) resistance of the fluid sample in the chamber directly and (ii) from the direct current determine a polarization resistance of the at least one electrode. | 12-26-2013 |
20140107928 | Evaluation of Low Resistivity Low Contrast Productive Formations - A method for identifying low resistivity low contrast high temperature high pressure productive subsurface formations rich in acid gases penetrated by a wellbore includes obtaining dielectric permittivity measurements of selected formations adjacent at least part of the wellbore. Nuclear magnetic resonance relaxometry measurements are obtained for the selected formations, the relaxometry measurements being calibrated to identify relaxation times corresponding to acid gases in high humidity at elevated pressure and temperature. Zones are identified for withdrawing formation fluid samples based on the dielectric permittivity and relaxometry measurements. | 04-17-2014 |
