Abstract: A silicone release composition having a non-gloss, i.e., matte finished, surface and a linerless label incorporating the silicone release composition. The release composition includes a crosslinked silicone-based polymer having microparticles of a polymeric wax at least partially embedded therein. The polymeric wax may be polytetrafluoroethylene, polypropylene or other polyolefin, or a hydrocarbon-based wax. The microparticles of polymeric wax cause incidental light to scatter upon reflection, giving the release composition surface matte appearance. This makes the release composition particularly useful for linerless labels on which bar coded information will be printed. Also, a method for producing linerless label stock. The method includes mixing an uncured silicone material with microparticles of a polymeric wax. The mixture is coated onto a substrate and exposed to UV radiation to cure or crosslink the silicone around the microparticles of wax.

Abstract: A system for controlling the composition of color coupler on a real time basis, the system comprises a mixer for mixing the color coupler with a non-permanent solvent for forming a preliminary solution. A heat exchanger receives the preliminary solution for altering the temperature of the preliminary solution, and a separator receives the preliminary solution from the heat exchanger for separating the preliminary solution into a color coupler solution suitable for use in producing photographic paper and into a residual vapor. An in-line viscometer receives the color coupler solution from the separator for determining the viscosity of the color coupler solution, and a process control system alters the temperature of the heat exchanger in response to a signal received from the viscometer for optimizing the composition of the color coupler solution.

Abstract: A method to reduce water coning in viscous oil formations during primary oil production wherein a horizontal wellbore is heated by circulating steam therein thereby heating a radial area near the wellbore. Near wellbore heating alters a pressure profile in the radial area near the wellbore. Reduced inflow pressure gradients near the wellbore flatten out a pressure sink associated with the wellbore. This reduces substantially water coning which allows more oil to be produced before high water production begins.

Abstract: A foam/steam injection method for forming fractures is a for reservoir penetrated by a horizontal wellbore. Steam is injected into said wellbore at a pressure sufficient to fracture the formation. Water which is used to make the steam contains a foamable composition in an amount sufficient to make a foam upon contact with steam. Steam and foam enter the wellbore and create a fracture in an oil-rich zone. Thereafter, foam blocks further steam entry into the created fracture which causes another fracture to form at a second interval along the horizontal wellbore. These steps are repeated until a fracture system is made along the length of the wellbore.

Abstract: A conduction heating, gravity assisted, single well, process for removing viscous hydrocarbonaceous fluids from a reservoir penetrated by a horizontal wellbore. Steam and a gas soluble in hydrocarbonaceous fluids are circulated into the wellbore at or below the reservoir pressure through an upper perforated conduit of the horizontal wellbore. Circulation is continued so as to allow steam to heat the reservoir by conductance while gas enters the hydrocarbonaceous fluids. Thus, heated hydrocarbonaceous fluids having a reduced viscosity flow from the reservoir around the horizontal wellbore where the fluids are produced to the surface by a lower conduit within the horizontal wellbore. The lower conduit is open along its length so as to be in fluid communication with the reservoir for the length of the horizontal wellbore.

Abstract: Compositions for lightweight, waterproof, cementitious materials comprise portland cement, aggregates, two admixtures, and water. A first admixture comprises a major portion of calcium chloride and minor portions of sodium silicate and a wetting agent. A second admixture comprises an emulsion of ammonium stearate. Methods for producing cementitious materials include a process for manufacturing strong, lightweight, waterproof building products such as roofing tile, imitation bricks, and the like.

Abstract: A method for recovering viscous oil from a formation having a bottom water zone below an oil containing zone. Steam is directed into the bottom water zone thereby heating this zone and an oil containing zone thereabove. Afterwards, steam injection is ceased and a gellable composition is directed into the bottom water zone where it forms a solid gel. Once the solid gel has formed, steam is injected into the bottom water zone where the solid gel causes it to flow upwardly into the oil containing zone. Oil, water, and steam are removed via a recompleted producer well.

Abstract: A process for increasing the production of hydrocarbonaceous fluids in a reservoir where foam is injected into a gravity override zone. Foam is injected into the override zone via a well placed in the zone. This foam injection wall is positioned between an injector and a producer well. During a steam-flooding or carbon-dioxide flooding, foam is injected into the override area via the foam injection wall thereby blocking the override area and causing flooding fluids to be directed into an oil rich overridden area. Foam utilized herein can be formed in-situ or ex-situ by a noncondensible gas and a surfactant.

Abstract: A method of ameliorating two-phase flow segregation during wet steam injection in a vertical injection well wherein a compartmentalized tray of variable depth is utilized. This tray traps a liquid phase of the steam near each perforation. A hole within the tray allows steam to pass through to a lower level in the well. In this manner, the liquid phase is held up near the perforations. Steam and water thus pass into the formation uniformly at each perforation. The degree of segregation may be controlled by the tray's depth. A deeper tray allows more water to be trapped near the upper perforations. A shallow tray favors segregation within the wellbore. More than one tray can be used.

Abstract: A process for closing pores in a bottom water zone where steam is directed so as to by-pass a zone of the formation containing hydrocarbonaceous fluids. Once a portion of the bottom water zone has reached a temperature in excess of about 300.degree. F., steam entry is ceased. Afterwards, a temperature activated gellable composition is placed into the bottom water zone. When the composition reaches that portion of the bottom water zone where a temperature in excess of about 300.degree. F. has been reached, the composition activates and forms a rigid gel. Thereafter, a steam flooding method is commenced. Steam is diverted from the bottom water zone and into an upper zone containing hydrocarbonaceous fluids.

Abstract: A cover and integral straining relief mechanism for an electrical cable multiprong connector, including a two-piece cover utilizing identical and interconnecting halves assembling as a whole connector, mount, and cover. A strain relief mechanism utilizing a cubical insert is included. The cubical insert is a plunger-like mechanism containing teeth-like undulation along its side which interact in a ratcheting fashion with mating undulations within the connector cover. The plunger is inserted into at least one opening in the connector and comes into contact with a cable entering the connector through the remaining and unused opening. The plunger comes into contact with the insulation about said electrical cable such as to hold the cable securely within the connector, thereby providing strain relief action.
