Abstract: A card package assembly and method of manufacture thereof allow simple and inexpensive production of desirable products, particularly useful for telephone debit cards. A web of card stock is imaged on both first and second faces with indicia (preferably variable and non-variable), and the faces are spot coated with plastic at spaced locations equal to the length of card package ultimately separated from the web. A card is formed from or out of each of the spot coated plastic locations, by die cutting, or with lines of weakness such as perforations. The form is narrower at the card, and adhesive patterns outside the card portions hold other panels of the package together once folded over to sandwich the card between other panels. The cards may be produced from a web one package wide, or from a web two or even more packages wide. A bang tail is preferably provided connected to the card, and of the same width, with a perforation separating the bang tail from the card and coupon indicia imaged on the bang tail.

Abstract: A resettable well stimulation tool is lowerable into a well bore on a length of tubing through which pressurized fluid may be forced into the tool to inflate a packer portion carried by the tool and then discharge a stimulation fluid into a portion of the well bore sealed off by the packer portion. During the inflation cycle of the tool pressurized fluid is forced downwardly into an annular tool body inflation chamber that communicates with an inflatable packer carried by the tool body. A perforated tube member coaxially carried in the inflation chamber serves to vertically distribute the inflation pressure along the length of the packer and assure its even inflation. In a straddle packer embodiment of the tool inflation and stimulation passages extend internally through the tool and are sealingly separated by an internal crossover structure, with the inflation passage being in communication with upper and lower packer members.

Abstract: A diverter for a subterranean well, a diverter retrieving tool and methods of diverting objects traversing the well and retrieving the diverter. The diverter comprises: (1) a body having a lower portion adapted to be coupled to a diverter anchoring structure and an upper portion having a slanted diverting surface, the diverter adapted to be placed within a main borehole of the subterranean well at a predetermined location and orientation proximate a junction of a lateral borehole with the main borehole, the slanted diverting surface adapted to redirect an object having a particular diameter and coming into contact with the diverter into the lateral borehole and (2) a compliant spring member associated with the slanted diverter surface.

Abstract: A packer apparatus with a circulating port. A housing of the packer has inflation passages, circulating passages, treating fluid passages, and equalizing passages defined therein. In a straddle packer embodiment, upper and lower packers are mounted on the housing on opposite sides of an outlet of the treating fluid passage. A circulation valve with a sliding differential pressure actuated valve sleeve is disposed below the packers. An inner mandrel is slidably received in the central opening of the housing. The mandrel has a mandrel bore and has upper inflation and circulating ports, lower inflation ports, upper and lower equalizing ports, a treating port and lower circulating ports, all of which communicate with the mandrel bore. The valve sleeve has a valve port. A lug and endless J-slot is operably associated with the housing and mandrel for controlling a telescoping position of the mandrel relative to the housing in response to reciprocation without rotation of the mandrel relative to the housing.

Abstract: A differential pressure operated valve for use as a circulating and/or deflation valve in a well bore. The valve comprises a housing defining first and second bores therethrough and a passage providing communication between the interior and exterior of the housing. A valve sleeve is slidably disposed in the housing and has a first outer surface slidably disposed in the first bore and a second outer surface slidably disposed in the second bore. A valve port is defined in the valve sleeve providing communication between a central opening thereof and the passage in the housing when the valve sleeve is in an open position. When the valve sleeve is closed, the valve port and passage are isolated from one another. The first and second outer surfaces of the valve sleeve define a differential area, and the valve is closed by fluid flow creating a differential pressure acting across this area. A spring biases the valve toward the open position.

Abstract: A fluid flow control valve having an adjustable opening pressure and using expendable components therein for use in pumping highly abrasive fluids therethrough.
