Inventor: SCHULTZ ROGER LYNN
IPC: E21B47/01
Filed: 2001-07-17
Abstract: A method and system to passively monitor cement integrity and reservoir/formation parameters near the wellbore (240). Different types (pressure, temperature, resistivity, rock property, formation property etc.) of sensors (210) are "pumped" into place by placing them into a suspension in the cement slurry at the time a well casing is being cemented, by placing them in gravel pack used in frackpacking, or by a deflected drilling tool. The sensors (210) are either battery operated, or of a type where external excitation, (EMF, acoustic, RF etc.) may be applied to power and operate the sensor (210), which will send a signal conveying the desired information. The sensor (210) is then be energized and interrogated using a separate piece of wellbore (240) deployed equipment wherever it is desired to monitor cement or formation conditions. This wellbore (240) deployed equipment could be, for example, a wireline tool.

Title: Method of preventing gas breakthrough in an oil bearing formation
Inventor: DAWSON JEFFREY C
IPC: C09K8/44
Filed: 2001-09-05
Abstract: A method of preventing gas breakthrough in an oil well, which includes first pumping a slug of an alkaline earth salt into the well bore, followed by a slug of spacer solution, and finally a slug of a fatty acid resin.

Title: Refrigeration defrost system
Inventor: LESAGE GAETAN
IPC: F25B5/02
Filed: 2003-07-11
Abstract: A refrigeration defrost system includes a frosted evaporator with an evaporator refrigerant vapor line and an evaporator refrigerant liquid line. A compressor with a suction inlet and a discharge outlet are both connected to a discharge manifold. The discharge outlet is connected to the evaporator refrigerant vapor line. A pressure regulator valve is located in a refrigerant bypass passageway between the discharge manifold and the suction inlet line and feeds refrigerant vapor, when a defrost cycle is required, from the discharge manifold into the suction inlet. A check valve is connected in series with the regulator valve to stop low pressure refrigerant vapor from the evaporator refrigerant vapor line from feeding into the suction inlet. The refrigerant vapor is fed from the compressor into the discharge outlet and into the evaporator through the evaporator refrigerant vapor line, which defrosts the evaporator.
