Patent CA-2261443-A1 (CA)
Inventor: PATERSON EDWARD MICHIE
IPC: A01K91/06
Filed: 1999-02-03
Abstract: A shaped piece of buoyant material attached to a fishing line between the fisherman and the hooking/weighting section acts as a lifting device for the hooking/weighting section. The buoyant piece because of its shape and/or angle relative to the direction of pull, will lift the hooking/weighting section clear of potential snags when the fisherman pulls on the line. The correct combination of buoyancy and weight will allow the unit to settle back to the bottom as soon as the line is no longer being pulled. The buoyant piece or pieces may be permanently fixed to the weighting portion of the hooking/weighting section during production. In a nonpermanent configuration the fisherman will affix the buoyant piece or pieces to the line at a distance from the hooking/weighting section as dictated by his preference.
Patent CA-2261480-A1 (CA)
Title: Application of aluminium chlorohydrate in viscosifying brine for carrying proppants in gravel packing
Inventor: COLLINS BRETT
IPC: E21B43/267
Filed: 1999-02-11
Abstract: New compositions have been discovered which arc useful as slurry concentrates to carry solid particles along in a fluid. A non-limiting example would be to carry proppants in a concentrate to a completion fluid being pumped downhole in a hydrocarbon recovery operation. The composition employs both a trivalent salt, such as aluminum chlorohydrate, as a viscosifying agent, and a surfactant.  Surprisingly, it has been discovered that a synergistic effect is present between the aluminum chlorohydrate and the surfactant in that less of each component is required when both are used together to suspend the same amount of solids, than if one or the other is used separately. The viscoelasticity of the concentrate may be easily broken by dilution; other mechanisms are also anticipated.
