Patent CA-2022505-A1 (CA)
Inventor: TOWNSEND GARNOLD
IPC: F16J15/00
Filed: 1990-08-01
Abstract: A segmented seal is disposed between a rotary heat-retaining body and its housing, the housing defining a hot flow path and a cool flow path through the housing and intersecting the heat retaining body, and the heat retaining body being movable to transfer heat from one flow path to the other. A plurality of serially-connected seal segments are attached to one of the body and the housing, the seal segments each extending along a seal line and overlapping one another along the seal line, the seal segments bearing against the other of the body and the housing to effect a seal.
Patent CA-2023281-A1 (CA)
Inventor: JONES LLOYD G
IPC: E21B43/04

Abstract: A method for gravel packing a well penetrating an unconsolidated or poorly consolidated subterranean oil or gas reservoir. The well can employ a borehole casing with perforation tunnels for fluid communication between the borehole casing and a substantial portion of the reservoir. A sand screen is located inside the well casing and in juxtaposition with the perforation tunnels forming an annulus between the borehole casing and the sand screen. One or more conduits are positioned in juxtaposition with the sand screen with openings to provide fluid communication between the conduit and a substantial portion of the annulus between the borehole casing and the sand screen. A slurry of gravel is injected down through the annulus between the borehole casing and the sand screen until the annulus being packed thereby plugging the annulus between the casing and the sand screen, the slurry of gravel will continue to flow down the conduit and into the annulus below the gravel bridge thereby completely packing the annulus between the sand screen and the borehole casing. The oil or gas in the reservoir is then produced through the gravel packed borehole casing and the sand screen. If desired, the slurry of gravel may be injected down the well and up the conduit and annulus to accomplish complete packing. The method is also applicable to placing gravel packs in an open-hole wellbore adjacent to a substantial portion of an unconsolidated or poorly consolidated subterranean oil or gas reservoir.

Abstract: Insect control agents comprising genes encoding proteins affecting the growth, development or behavior of an insect are provided. The gene is either activated to prevent insect molting and pupation or is inactivated to reduce the feeding behavior, inhibit growth and result in the earlier death of the insect host. Such an insect control agent is exemplified by a baculovirus in which the gene encoding ecdysteriod glucosyltransferase has been inactivated. Additionally, such baculoviruses may be further modified to express a protein which affects ecdysis. Methods for producing the insect control agent and methods of controlling insects by exposing them to the insect control agent are also included.
