  • Publication number: 20200173907
    Abstract: No reliable test presently exists for predicting the amount or type of corrosion a metal surface may experience during field use, particularly when the corrosion can be a result of both acid-induced corrosion and microorganism-induced corrosion mechanisms. Apparatuses affording more field-like testing conditions may comprise: a one-pass fluid train comprising a reservoir configured to maintain a fluid at a first temperature state under anoxic conditions; a pre-conditioning chamber in fluid communication with the reservoir and configured to receive a defined volume of the fluid; an autoclave chamber having an impeller in fluid communication with the pre-conditioning chamber that is configured to receive the defined volume of the fluid from the pre-conditioning chamber; and one or more sampling receptacles in fluid communication with the autoclave chamber that are configured to receive the defined volume of the fluid while maintaining anoxic conditions.

  • Patent number: 10466153
    Abstract: Herein disclosed are apparatuses and methods related to coreflood testing apparatuses and methods for determining key physical properties of core specimens. More particularly, disclosed herein are coreflood inlet end-piece designs, coreflood testing systems and coreflood testing methods to enable simultaneous testing to obtain necessary data for determination for determining key physical properties of core specimens, which include the relative permeability and the capillary pressure, as well as, optionally the wettability of the core sample.

  • Patent number: 9587474
    Abstract: Methods and systems for completing a well including injecting a stimulation fluid to stimulate a first interval in the reservoir. The stimulation fluid is at a pressure sufficient to open a number of check valves in the first interval, allowing stimulation fluid to flow into the first interval. A number of ball sealers configured to block flow through the check valves are dropped into the well to stop the flow of the stimulation fluid into the first interval and begin treatment of a second interval. The stimulation fluid is injected to stimulate a subsequent interval with pressure sufficient to open a number of check valves in the subsequent interval, allowing stimulation fluid to flow into the subsequent interval. The dropping of ball sealers is repeated until all intervals are treated.

The dropping of ball sealers is repeated until all intervals are treated. At least part of the check valves are configured to allow stimulation fluid to flow into a distribution chamber with multiple openings.

  • Publication number: 20150323441
    Abstract: A QCM sensor apparatus comprising a QCM mounting insert having a first opening, a second opening, and a barrier fluid chamber disposed between the first opening and the second opening, and a QCM wafer sealably coupled to the second opening, wherein the QCM wafer has an electrode contact exposed to the barrier fluid chamber and a sensitive layer that is not exposed to the barrier fluid chamber.

  • Publication number: 20140305658
    Abstract: A contoured boss for conforming to an outer surface of a tubular member for deployment within a subterranean formation, the contoured boss comprising a valve receiving body having a contoured outer surface that extends radially outward from an outer surface of the tubular member; and passage for receiving a valve, the passage extending through the valve receiving body. A method for facilitating stimulation treatments in completions and a method of centering a tubular member having an outer surface within a borehole are also provided.
