Abstract: A multi-purpose handheld tool apparatus for emergency and rescue personnel. The apparatus, incorporates a handle operatively coupled to a hatchet head portion and a saw blade hingeably coupled to an end of the handle opposite the hatchet head portion. The saw blade is able to move between a recessed inoperative position at least partially received with the slot or cavity of the handle to an operative deployed position. The inventors have determined that apparatus provided herein is able to receive commercial saw blades designed for a variety of reciprocating saws. Additionally, by way of example, the inventors have determined that apparatus provided herein can permit the user to be effective in a variety of emergency and rescue operations with both ease and efficiency utilizing multiple tool application embodiments.

Abstract: Disclosed herein are embodiments of an apparatus for delivering lost circulation material, particularly cottonseed hulls, into oil and gas drilling pits. According to one exemplary embodiment, a lost circulation material delivery apparatus for delivering lost circulation material from a bulk source of the material into a drilling well mud pit for controlling lost circulation within an oil or gas drilling well bore can include a bulk source of lost circulation material positioned in the vicinity of but removed from the drilling well mud pit. The apparatus can also include a sorting mechanism in receiving communication with the bulk source where the sorting mechanism includes a lost circulation material metering portion. A lost circulation material conveying portion can be in material receiving communication with the material metering portion at a first end portion and in material expelling communication with the drilling well mud pit at a second end portion.

Abstract: Disclosed herein are embodiments of a method and system for delivering lost circulation material, particularly cottonseed hulls, into oil and gas drilling pits. According to one exemplary embodiment, a method of delivering lost circulation material from a bulk source to a drilling well mud system for controlling lost circulation within a drilling well bore includes positioning a bulk container of lost circulation material at a location in the vicinity of but removed from drilling well mud system. Lost circulation material is introduced from the bulk container into a sorting mechanism. The method further includes conveying the lost circulation material with a moving device from the sorting mechanism to the drilling well mud system along a path separated from the moving device.

Abstract: A method of extracting from an oil bearing product at below a select temperature. The method includes providing an oil bearing product at a temperature at or below the select temperature. A liquid extraction solvent that is a gas under standard temperature and pressure is provided, with the extraction solvent being maintained at a temperature below its boiling point at ambient pressure and below the select temperature and at substantially ambient pressure. The oil bearing product is contacted with the extraction solvent at ambient pressure for a period sufficient to extract a select amount of the oil from the oil bearing product resulting in a reduced oil content product and an oil bearing extraction solvent.
