    摘要: A mold pin is formed of a longitudinally extending rod-like body with a collar extending laterally or transversely from the body. The collar is of peripheral and longitudinal dimensions similar to those of a protrusion extending from the surface of a mold tray (mold casting or half), such that when the mold pin seats in the protrusion, the protrusion and the collar define a boss in the mold tray.

    摘要: Cement retarders for well cements are based on hydrophobins. Hydrophobins are proteins or polypeptides that form hydrophobic coatings on surfaces. The size of the hydrophobins is preferably between about 100 and 350 amino acids, and the preferred hydrophobin concentration is between about 0.001% and 1.0% by weight of cement. Portland cement is the preferred well cement. Cement slurries containing hydrophobins are useful for both primary and remedial cementing applications.

    摘要: A method includes providing a treatment fluid that is a viscous fluid. The viscous fluid may be greater than 0.01 Pa-s, greater than 0.1 Pa-s, and/or a cross-linked polymer based fluid. The method further includes determining a fines migration composition soluble in an aqueous phase of the treatment fluid that is compatible with the treatment fluid, and that interacts to secure fines in an earth formation intersecting a wellbore within a fines reaction time. The method further includes adding an amount of the fines migration composition to the treatment fluid, and treating the earth formation with the treatment fluid. The method includes leaking off a portion of the treatment fluid into the earth formation, and providing a residence time of the leaked off portion of the treatment fluid in the earth formation, where the residence time meets or exceeds the fines reaction time.
