Abstract: Devices for monitoring, calibrating and maintaining a manufacturing robot. The first device comprises a reference pin mounted to a first member and a reference aperture located on a second adjacent member wherein the reference pin is inserted into the reference aperture when the two members are at their zero reference location. A second device checks tip alignment by periodically passing the welding tip of a welding torch through a V-shaped notch in a gauging block. The gauging block is electrically conductive and if the tip contacts the sidewalls of the V-shaped notch an electrical circuit is completed signalling the robot controller of tip misalignment. A third device comprises a shielding gas monitor having a closed tube to which the welding torch is applied for expelling shielding gas into the tube. The tube is in fluid communication with a flow gauge that measures gas flow and signals the controller if gas flow is insufficient.

A polyepoxide resin composition for coating and bonding to a material, a composition useful for forming a hard permeable mass in a remote location and a method of continuously forming and suspending consolidatible resin composition coated particulate material in a gelled aqueous carrier liquid and transporting the coated particulate material to a remote location where the material is consolidated are also provided.

Abstract: A method of preventing gas coning or fingering from a gas cap in an oil producing well is provided. A polymerizable material is injected into the gas cap under conditions such that it polymerizes to form a substantially impermeable zone or layer above the oil bearing formation to prevent gas from flowing into the oil well during production.

Abstract: A method of evaluating a gravel pack slurry uses a fast neutron source and a thermal neutron detector to produce responses from which gravel settling rate, packing efficiency, gravel concentration, porosity and density can be determined. The method can be applied to either static or dynamic slurries in either a laboratory test environment or an actual well environment.

Abstract: An apparatus and method for locating and electrically isolating failed cells in a network of cells is disclosed. The apparatus includes a device for sampling voltage and current levels of each of the cells of the battery. Another device compares the sampled voltage and current levels to voltage and current limits to determine whether a cell has failed. If a cell has failed, control circuitry produces an activation signal which is conveyed to a switch associated with the failed cell. The activation signal drives a heating element of the switch. The heating element, which surrounds a fusible link of the switch, melts the fusible link. The fused link congregates at the base of the switch. In the case of a parallel network of cells, the fused link forms an open circuit, while in the case of a series network of cells, the fused link forms a bypass circuit. Consequently, the switch isolates the failed cell from the good cells remaining in the battery.

Abstract: A new method is provided for improved degradation of metal-crosslinked polymer gels which are useful in oil and gas well treating operations. In this method an esterified carboxylated chelator is added to the gel. At elevated temperatures, the esterified chelator undergoes hydrolysis to form an acid and an active ligand which subsequently removes the crosslinking metal ion from the gel and hydrolyses the polymer.

Abstract: The system for controlling a plurality of devices includes a central processor that receives information from a user, translates the information into a command and sends the command to a communication processor. The communications processor formulates a device command to send to a remote device processor which is connected in close proximity to a device that the user wants to control. The communication processor also receives status information back from the device processor which has been accessed. The device processor receiving a command uses the command to control the device attached to the device processor. Each device processor is able to monitor the commands sent to other device processors and can be set to use these commands to control their attached device. This method of monitoring allows many devices to be controlled simultaneously with very few commands.

Abstract: A method of preparing high density particulate slurries is provided whereby slurries containing in excess of 23 pounds of particulate per gallon of fluid can be introduced into a subterranean formation. In accordance with the method, a viscosified pad fluid is introduced into a wellbore to create a filter cake in a desired zone within a subterranean formation. The high density slurry then is introduced into the formation to substantially fill any annular space present without significant settling. This permits the coating of the entire exterior surface of highly deviated casing exposed within a wellbore.

Abstract: An improved method for completing wells formed in both consolidated and unconsolidated formations is disclosed. Further, methods are disclosed for completing deviated wells formed in consolidated formations which require stimulation by hydraulic fracturing. The present invention specifically relates to more efficient, less expensive techniques for well completion comprising novel techniques for the utilization of permeably consolidatably, resin coated particulates.

Abstract: Methods of treating a previously fractured bacteria contaminated subterranean formation penetrated by a well bore whereby the bacteria contamination is substantially reduced or eliminated are provided. The methods basically comprise mixing a bactericide with a fracturing fluid in an amount effective to contact and kill bacteria contained in the formation and pumping the mixture into the formation at a rate and pressure sufficient to re-fracture the formation. The re-fracturing of the formation causes the bactericide to be distributed throughout the formation and to contact and kill bacteria contained therein without adversely effecting the productivity of the formation.

Abstract: The amount of protrusion of an end of a standard length push pin from a stationary part of a solenoid-actuated valve is measured at a certain point in the valve fabrication process. Then before the armature is assembled into the valve, a depression whose depth is based on the push pin protrusion measurement is coined into the end of the armature that is to bear against the protruding end of the push pin. When the armature is assembled, the protruding end of the push pin seats in the depression that has been formed in the end of the armature with the result that the air gap between this end of the armature and the stationary part from which the push pin protrudes is the desired thickness. The process is well-suited for automated operation so that maximum production efficiencies can be attained.

Abstract: The present invention provides a method of consolidating an incompetent subterrnean formation. An acid curable resin consolidating fluid is positioned within casing in a wellbore in the vicinity of perforations through the casing. A gas generating charge positioned within the casing then is ignited to generate gas pressure which rapidly forces the consolidating fluid through the perforations and into the subterranean formation while substantially simultaneously catalyzing the resin composition. The consolidating fluid is caused to rapidly harden to consolidate the formation in the vicinity of the perforation without any significant permeability loss.

Abstract: A dual stream thin edge orifice disk is defined as a disk having a pair of orifices positioned to direct the flow of fluid from the interior portion of a valve into two different streams. The dual streams may be parallel or typically diverge at an angle for directing the stream to two adjacent engine valves in the situation wherein the valve is an electromagnetic fuel injector for an internal combustion engine. To have the dual stream flow in a direction that is not parallel, the area of the disk surrounding the dual orifices is embossed and the orifices are positioned along the sides of the embossment between the base and the apex thereof. The manufacturing of the accurately sized orifices in the disk is accomplished by means of a progressive die. One of the stations of the die provides a coining operation on the orifice. Such coining operation is adjustable by means of a micrometer adjustment.
