    • Methods for creating packers at a desired location or locations within a wellbore for use in specific wellbore applications. A slurry of fluid medium and hydrolysable particulate matter is flowed to a downhole position and dehydrated. At this location, the particulate matter is released from the fluid medium and accumulated. The continual accumulation of the slurry and consequent deposition of particulate matter creates a degradable packer at the desired location within the wellbore. The particulate matter may be formed of an acid particle which may be removable, degradable, or hydrolysable under certain conditions of temperature, time, hydration, pH, and/or pressure. Either simultaneous with or subsequent to a wellbore activity, the packer is partially or completely removed from the wellbore.
    • 在井眼中的期望位置或位置处创建包装器以用于特定井眼应用的方法。 流体介质和可水解颗粒物质的浆液流入井下位置并脱水。 在这个位置,颗粒物质从流体介质中释放并积聚。 浆料的持续积累和随之而来的颗粒物质的沉积在井眼内的所需位置产生可降解的封隔器。 颗粒物质可以由在特定温度,时间,水合,pH和/或压力条件下可去除,可降解或可水解的酸性颗粒形成。 与井眼活动同时或之后,封隔器部分或完全从井筒中移除。

    • 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.

    • This invention relates to compositions used in treating subterranean formations, which include a hydrated polymer, and a dry blended multi-functional component. The hydrated polymer and dry blended multi-functional component are mixed at the ground surface of a wellsite, and subsequently injected into the formation providing controlled delay in crosslinking to achieve targeted fluid viscosity properties. 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. Also, methods of hydraulically fracturing a subterranean formation, as well as cleanup operations and gravel packing a wellbore are provided as well.
