Appl. No.:

12/732680

Inventors:

Richard F. Lukay - Houston TX, US
Jarod Hammar - Cypress TX, US

Assignee:

OFI TESTING EQUIPMENT, INC. - Houston TX

International Classification:

G01N 11/00
G01N 1/10

US Classification:

73 5442, 7386311

Abstract:

A test sample heating apparatus and method includes a heating jacket that applies heat to a sample vessel containing a test sample. The heating jacket has a vessel-receiving recess that is sized and shaped to allow the sample vessel to be placed within the recess with limited annular spacing between at least part of the sample vessel exterior surface and at least part of the heating jacket recess interior surface. Proximate surfaces of at least one of the heating jacket and the sample vessel may be coated with a dark coating to enhance heat transfer.

Appl. No.:

10/425228

Inventors:

Richard F. Lukay - Houston TX

Assignee:

OFI Testing Equipment, Inc. - Houston TX

International Classification:

G01N 1114

US Classification:

73 5428, 73 5433, 73 5435, 73 5438

Abstract:

A rotational viscometer includes a cylindrical bob attached to a bob axle, a concentric sleeve exterior of the bob, a motor for inducing rotation in the sleeve, a biasing spring attached to the bob axle for resisting axle rotation, and a measurement system comprising an electric field transmitter, an electric field receiver and a rotor extending intermediate the transmitter and receiver. The rotor is attached to the bob axle so that rotation of the bob axle and the rotor presents a measurable deviation of the electrical field received by the electrical field receiver. A processor calculates the angle of displacement of the bob from that sine and cosine of the received electrical field and transmits readable output in the form of a sample viscosity value to a display.

Abstract:

Exemplary embodiments of a high temperature aging cell provide a metal-to-metal fluid seal, and generally include a central tension post containing a flange having an inclined surface; and a seal ring concentrically arranged thereon, its outer circumference positioned at least partly intermediate the flange and the cell interior surface. In various embodiments, a thrust ring retains the seal ring; a thrust washer engages the thrust ring; a tension ring is attached to the tension post for biasing the thrust ring toward the flange; and an outer cap retains various components in relation to the aging cell. A pressure control device allows for pressure elevation.Exemplary embodiments of a sample aging method generally include aging a liquid sample by sealing the sample in the cell via biasing of the seal ring into sealing engagement with an interior surface of the cell. Subsequent sample treatment may involve elevating its temperature and/or pressure.

Assignee:

OFI Testing Equipment, Inc. - Houston TX

International Classification:

G01N 33/38
B65D 41/04

Abstract:

Embodiments of a sample testing system of the present invention generally include two internally threaded caps; an externally threaded outer tube having a tapered internal bore and external circumferential grooves proximate each end thereof; an O-ring seated in each groove; and a plurality of inner tube sections cooperatively arranged to form an externally tapered inner tube structure that is disposed within the outer tube; wherein each cap is sealingly attached to an end of the outer tube via threading engagement therewith. Various embodiments utilize at least one closed-ended cap and/or at least one cap having a port extending through an end thereof, which may also incorporate a piston cavity and a piston having two circumferentially disposed O-rings. Embodiments allow for inner tube structure removal and separation of the inner tube sections for cured sample recovery. Embodiments of a method of using the system to cure a sample are also provided.

Inventors:

John D. Norwood - Houston TX, US
Richard F. Lukay - Houston TX, US

Assignee:

OFI TESTING EQUIPMENT, INC. - Houston TX

International Classification:

F16K 17/40

Abstract:

A pressure relief tool including a stem connected to a plunger assembly, a plunger rod slidably retained in the plunger assembly and the stem, a stem connector for connecting the stem to a test cell vent opening, a handle operably connected to the plunger rod, and a vent tube extending from said plunger assembly, the vent tube fluidly connected to an annular opening within the stem. A method of opening a blockage and venting pressure from a high temperature high pressure test cell includes attaching a pressure relief tool of the present invention to the test cell vent opening; advancing the plunger rod through the vent opening, puncturing the blockage in the test cell to allow fluid flow to the vent opening, and allowing fluid to exit the test cell through the annular opening in the stem and the vent tube.
