An exemplary paddle includes a central shaft having a first end and a second end. One or more lateral blades extend laterally from the central shaft, and each lateral blade including a geared end positioned adjacent the central shaft and a distal end opposite the geared end. Each lateral blade provides a blade gear at the geared end. A drive shaft is movably positioned within the central shaft and operatively coupled to the one or more lateral blades such that rotation of the drive shaft about a central axis rotates the one or more lateral blades about a corresponding one or more blade axes. The one or more lateral blades are able to move between a horizontal position and a vertical position via independent actuation.

Actuatable paddle and methods of use

Corrosion-resistant refractory binder compositions may include high alumina cement, high-alumina refractory aluminosilicate material, and phosphorous material. Examples of high-alumina refractory aluminosilicate material include crushed firebrick, firebrick grog, refractory mortar, fire clay, mullite, fused mullite, and combinations thereof. The binder composition may be mixed with sufficient amount of fluid such as water to form a slurry and introduced into a wellbore penetrating a subterranean formation, where it may be allowed to set at a point downhole. Such compositions, once set, may exhibit enhanced corrosion and heat resistance. Such compositions, once set, may additionally be cured. Curing may take place at higher temperatures and/or pressures, and may furthermore increase temperature resistance and/or strength of the set binder composition. In addition, the inclusion of high-alumina refractory aluminosilicate material may provide for enhanced consistency in such binder compositions formulated from different batches of high-alumina refractory aluminosilicate material.

Corrosion-resistant refractory binder compositions and oil well completion and production operations

Corrosion-resistant refractory binder compositions may be formed with a calcium ion source, high-alumina refractory aluminosilicate pozzolan, and water. Any one or more of such components may individually be non-cementitious. Examples of high-alumina refractory aluminosilicate pozzolan include crushed firebrick; firebrick grog; and mixtures of silicate and any one or more of corundum, high-alumina ceramic, and bauxite; refractory mortar; fire clay; mullite; fused mullite; and combinations thereof, among others. A binder composition may be mixed with sufficient amount of water to form a slurry, which slurry may be introduced into a subterranean formation (e.g., via a wellbore penetrating the subterranean formation). A plurality of the non-cementitious components may react in the presence of water when exposed to suitable conditions so as to enable the binder composition to set. Such compositions, once set, may exhibit enhanced corrosion and/or heat resistance as compared to other binder compositions.
