摘要:
The whipstock assembly comprises an assembly casing (9) with preformed windows connected to production casing (7); a landing tube (21) is located within assembly casing (9) for receiving whipstock shaft; a key is located within tube (21) for cooperation with J-slot on whipstock shaft. The whipstock consists of upper (49) and lower (55) portion which are fixed against relative rotation by splines. The assembly casing (9) with landing tube (21) is positioned in the borehole using a gyro survey tool for correct orientation of the windows. After a first side hole has been drilled, upper portion (49) is raised and rotated to place wedge surface (51) for drilling a second side hole. Tube (21) is initially closed by a cap containing a marking fluid; after the cap has been drilled out the marking fluid indicates the removal of the cap. In a second embodiment two vertically spaced side holes are drilled.

A composition and method of absorbing animal dross. In one embodiment, the composition comprises discrete particles (about 50 microns to about 3350 microns, preferably about 600 microns to about 3350 microns in size) of a non-compacted water-swellable bentonite clay that effectively absorbs animal dross and simultaneously agglomerates into a sufficiently large and stable mass, thereby permitting physical separation of the soiled and wetted water-swellable bentonite clay particles from discrete particles of the unsoiled and unwetted water-swellable bentonite clay even after partial drying of about 1 to about 24 hours at room temperature, without substantial sticking to animal paws and fur. In another embodiment, the composition comprises discrete particles of a combination of non-compacted water-swellable sodium bentonite clay and calcium bentonite clay that effectively absorbs animal dross and simultaneously agglomerates into a water-dispersible but physically stable mass, thereby permitting physical separation of the soiled and wetted bentonite clay particles from discrete particles of the unsoiled and unwetted water-swellable bentonite clay, and has sufficient water-dispersibility for disposal through a household plumbing or sewer conduit without clogging.
摘要:
A method of treating a water-swellable clay, initially having a Fe.sup.+3 /Fe.sup.+2 ratio of at least 1.0, preferably at least 3.0, and most preferably in the range of about 5.0 to about 15.0, after the clay has been mined and dried. After the common initial drying of the clay to a moisture content of 12% or less, the clay is re-wetted to a moisture content of more than 12% by weight, preferably at least about 15% or more, based on the dry weight of the clay, then re-dried to a moisture content of 12% by weight or less, based on the dry weight of the clay. This re-wetting and re-drying processing of a dried clay unexpectedly improves the water absorbency, and viscosity properties; increases the effectiveness of the clays as binders in sand molds and iron ore pelletizing; unexpectedly increases the rheology properties of the clays for oilwell drilling fluids, and lost circulation fluids, and as a suspending agent in the cosmetics and pharmaceutical industries; improves the binding characteristics of the clays to act as a binder for iron ores, such as taconite, and sand molding (foundry industry); and provides unexpectedly increased water absorption in forming water-swellable clay-based water barriers.

A method of improving the yield of a germinating sod crop and a method of promoting the root formation and the vegetative growth of transplanted sod utilizing an aqueous gel including a highly-absorbent, crosslinked, mixed salt of homopolymerized or copolymerized acrylic acid. The aqueous gel utilized in the method of the present invention demonstrates an improved sod crop yield and improved sod growth even in the absence of plant nutrients.
摘要:
A composition and method of absorbing animal dross. Discrete particles of a composition comprising a water-swellable bentonite clay absorb animal dross and related liquids, and simultaneously agglomerate into a sufficiently large and stable mass therefore permitting physical separation and removal of the wetted mass of particles from unwetted particles of the composition. Removing the wetted and agglomerated composition particles from the remaining unwetted composition reduces or eliminates offensive odors produced by dross-soaked particles.

A memory is provided for receiving and storing the customer order status information. The customer order status data includes product order information, scheduled and actual shipping dates and each customer's telephone number. A telephone dialer is provided for dialing customer telephone numbers. Customer order status data is sorted by each customer's telephone number and a sepatate customer report file is generated for facsimile transmission to each identified customer. The customer report facsimile is automatically transmitted to each of the identified customers.
摘要:
A method of constructing an in-ground liquid barrier in separate sections with liquid tight joints between the sections. A barrier area is excavated and the sections formed therein, preferrably by initially filling the excavation with a liquid sealing slurry and sequentially displacing portions of the slurry with a liquid impermeable barrier material to form barrier sections which are mutually abutting along leaky interfaces. A bore is drilled between adjacent sections in a direction generally transverse to the direction of leakage, and filled with a liquid sealing material to seal the joint. The sealing material preferrably comprises a dry, hydro-expandable bentonite composition which expands to form a slurry sealant by permitting liquid to seep between the barrier sections into the bore and contact the bentonite therein.

A drillable debris barrier tool is positioned under a stage tool to protect tools therebelow from contamination with debris from the stage tool, as it is drilled out. The debris barrier tool includes features that facilitate drill up of stage tool debris and reduce the size of debris generated from removal of the barrier tool.
