    摘要： The present invention provides a method of controlling fluid loss to a permeable formation penetrated by a wellbore. A novel fluid loss agent is prepared by forming a crosslinked polymer gel which then is sheared to break the gel into discrete particles of a particular size range. A slurry then is formed of the particles by dispersing the particles in an aqueous fluid having a density similar to that of the gel particles. The slurry then is introduced into contact with the permeable formation and a filter cake of the particles is formed upon contact with the formation and loss of the slurrying fluid to the formation. The filter cake provides further fluid loss control to the permeable formation.

    摘要： The present invention provides improved methods of placing proppant in fractures formed in a subterranean zone to prevent the subsequent flow-back of the proppant with fluids produced from the zone. The methods are basically comprised of the steps of depositing a mixture of hardenable resin composition coated proppant and uncoated proppant in the fractures and then causing the resin composition to harden into stationary permeable masses in the fractures.

    摘要： The addition of an elastomeric material in intimate mixture with resin-coated particulates for fracturing, gravel packing or other formation treatments decreases or substantially eliminates the flowback of particulates whether proppants or formation fines while stabilizing the particulate and importing elasticity thereto within the formation. Preferred elastomeric materials include, polyolefins, polyamides, polyvinyls and cellulose derivatives in the form of particles, ribbons, fibers or flakes.

    摘要： A gun sight mount used in association with a gun barrel, such gun sight mount positioned on a axially rotatable shaft member disposed at an acute angle to the axis of the gun barrel, offsetting such sight mount to a side of such gun barrel. A handle causes rotation of the shaft member and sight mount such that the sight mount moves from a position where its axis is parallel to the axis of the gun barrel to a position where its axis is pointing downward and outward from the direction of the axis of the gun barrel to a point selected for the desired range whence the sight is then aimed at the target which action then elevates the gun barrel for the correct range and offsets the gun barrel from the target to adjust for the projectile's drift in order to aim the projectile accurately to hit the target.
