A perforating gun assembly is set forth. It incorporates a swivel connected with a cable head assembly and a navigation system for determining the instantaneous angle of the tool with respect to a vertical reference. There are first and second spaced cages formed of sleeves supported on bearing assemblies. The sleeves support free wheeling rollers which engage the casing when the tool is in the slant hole region of the well. There is an eccentric which falls downwardly, i.e., pointing toward gravity, and thereby defines a vertical reference and hence a horizontal reference. This eccentric mounts an elongate tubular housing for the shaped charges. Initially, the angle of firing of the shaped charges is adjusted at the time of installation with respect to the horizon and that in turn is correlated to the formation of interest in the well borehole which is then perforated with perforations which are parallel to the formation bedding plane.

A composition for preparing water based mold washes which contains a clay of high swelling capacity in water, certain water soluble acrylic polymers, a particulate, refractory material and a solids suspension control agent comprised of a peptizer and a flocculant.

The viscosity of liquid organic systems is increased by adding thereto an organophilic clay gellant which is the reaction product of a smectite clay having a cation exchange capacity of at least 0.75 milliequivalents per gram and from 1.00 to less than 1.20 milliequivalents per gram of clay of a methyl benzyl dialkyl ammonium salt, wherein the two alkyl groups independently contain from 16 to 18 carbon atoms, and from 0% to 1% water in the absence of a polar organic dispersant for the gellant.

An organophilic clay gellant having enhanced dispersibility in organic systems is prepared from the reaction product of a smectite-type clay having a cation exchange capacity of at least 0.75 milliequivalents per gram and from 1.00 to less than 1.20 milliequivalents per gram of clay of a methyl benzyl dialkyl ammonium compound, wherein the compound contains 20 to 35% alkyl groups having 16 carbon atoms and 60 to 75% alkyl groups having 18 carbon atoms.

A kite made out of a box top of the type of box formed of a light weight rigid plastic foam material, such as the substantially rectangular Polystyrene boxes used in dispensing hot food, particularly the type of such boxes having tops provided with a peripheral lip and a longitudinal slot in one longitudinal lip, midway of the ends of the box. A 1 inch tape, such as the tape commonly known as Engineer's flagging, of approximately 30 feet in length, is secured to the box top for a tail and a pigtail, and a string is attached to the flagging on the opposite side of the box top and the kite is ready to fly.
