摘要： A technique involves a packer formed as an expandable packer with an internal expandable bladder. The expandable bladder is formed with a section that is radially enlarged relative to an axial end of the expandable bladder when the bladder is in a relaxed state. The bladder configuration enables use of a reduced expansion ratio while still allowing expansion of the packer to a desired large diameter.

摘要： Disclosed are apparatus and methods for preparing wellbore viscous treatment gels from dry polymer and water. The apparatus includes an eductor which slurries dry polymer with water, at least two input tubes, wherein one input tube is connected with the eductor, and another to a water source. The apparatus also includes a mixing chimney connected to the input tubes. The mixing chimney includes a lower input section with inlets connected to the input tubes wherein a jet of metered dilution water is applied at high pressure to the incoming polymer-water slurry stream. This mixture is then accelerated in a circular, and preferably upward, motion where it is sheared against the wall of a central section of the chimney, without the use of an impeller. The chimney further includes an output section that comprising holes circumferentially located, through which the mixture passes from the central section and into a hydration tank. The mixture exiting the chimney is polymer-water gel which is essentially fully mixed and de-aerated, and at least partially hydrated.

The hydrated polymer may be a guar, hydroxypropyl guar, carboxymethyl guar, carboxymethylhydroxypropyl guar, synthetic polymers, and guar-containing compounds. The dry blended multi-functional component may include a crosslinker and a chelating agent, and the well treatment fluid may further include an activator mixed with the hydratable polymer. The chelating agent may be a polyols, gluconate, sorbitol, mannitol, carbonate, or any mixtures thereof. The crosslinker may be any source of boron, alkaline earth metal borates, alkali metal borates, zirconium compounds, titanium compounds, or any combination thereof, while the activator may be a caustic soda or magnesium oxide compound. The invention further provides methods for producing a well treatment composition including providing a hydrated polymer, and providing a dry blended multi-functional component.

摘要： A chopper mechanism for providing a fiber to a fluid at an oilfield. The chopper mechanism may be employed to process the fiber from an uncut form to a cut form in order to provide a mixture of the fluid and the fiber with flowback inhibiting character. Techniques of employing the chopper mechanism may be utilized at the site of an oilfield for applications such as fracturing, cementing, and drilling. Additionally, the chopper mechanism itself may be made available as a large high capacity chopper assembly, or a smaller handheld chopper gun for slower rate fiber supply operations.

摘要： An aeration system for circulating an aerating fluid through a chemical composition within a container. The aeration system is closed-loop such that the aeration fluid is supplied by a fluid supply system to the interior of a container to aerate the chemical composition therein. The aeration fluid is returned to the fluid supply system for subsequent redelivery to the container. A filtering mechanism may be employed to remove large particulate matter from the aeration fluid prior to flowing back to the fluid supply system. The aeration process improves the flowability of the chemical composition thus facilitating the transferring and/or discharging of the chemical composition from the container. The aeration process may occur during transport, prior to discharging, and/or during a discharging or transferring operation.
