A method for strengthening a subterranean formation by injecting an aqueous gellable composition containing a cross-inkable polymer into the subterranean formation through a wellbore to increase the strength of the subterranean formation while retaining the ability of the subterranean formation to produce fluids.

A method for steering the payload beam of a satellite in a non-geostationary orbit toward an intended service area having known geographical dimensions in order to obtain improved pointing performance with a corresponding reduction in the demand on onboard hardware and software systems. The method comprises the steps of determining a subterranean target point and a direction fixed in the payload beam, calculating the orientation that points the payload beam direction through the subterranean tar...

A method for consolidating a subterranean formation to control the production of particulates therefrom. A specific consolidating solution comprised of an allyl monomer and an initiator is injected into the formation where it is allowed to set at an elevated temperature to harden and form a permeable, consolidated mass. The allyl monomer is an allyl ester selected from the group of diallyl orthophthalate, diallyl isophthalate, diallyl terephthalate, diallyl benzenephosphonate, diethylene glycol ...

A board game which contains a plurality of tokens that are moved among various slots of a board. The tokens may fall through some of the slots and disappear from the game. The board game includes a first board that has a plurality of slots. The slots are arranged in a number of rows and columns. Each row corresponds to a game space. Each game space has one or more slots. The players take turns spinning a dial and moving a token a number of game spaces along the board. The player may insert the t...

Toxic wastes including naturally occurring radioactive materials are disposed of into subterranean earth formation zones which are bounded both above and below by zones which have higher in situ compressive stresses. The materials are prepared in a slurry of finely ground solids and a carrier liquid and are injected into a fracture created in the disposal zone by a process which includes initiating and extending the fracture with a fracturing fluid having a filter cake building solids material e...

A sprinkler head support apparatus and pipe support apparatus for an underground sprinkler system. The sprinkler housing support includes an open cage to permit drainage of water from the sprinkler head housing. The pipe support and pop-up sprinkler housing support can be placed completely beneath the soil limiting the exposure of the sprinkler system to above ground activities and possible damage. The pipe supports are made from a durable plastic and hollow inside to permit compact stacking in ...

A subterranean filter to remove particles from production fluid in a well includes a perforated inner member, at least one filter membrane made of a non-woven polymer material and a metal braided layer installed around the membrane and inner member to provide a filter having improved permeability and resistance to chemical and physical forces.

The present invention provides improved compositions and methods of using the compositions for sealing subterranean zones. One composition of the invention is comprised of water, an aqueous rubber latex, an organophilic clay, sodium carbonate, an epoxy resin and a hardening agent for said epoxy resin.

Improved methods of cementing in subterranean zones penetrated by well bores are provided. The methods are basically comprised of the steps of preparing a cement composition comprised of a hydraulic cement, a biodegradable, substantially non-dispersing set retarder of low anionic character comprised of polysuccinimide and sufficient water to form a slurry, placing said cement composition in said subterranean zone and allowing said cement composition to set into a solid mass therein.
